This method combines the well-known reduction of Cu+2 to Cu+1 by protein in an alkaline medium (the biuret reaction) with the highly sensitive and selective colorimetric detection of the cuprous cation (Cu+1) using a unique reagent containing bicinchoninic acid.1 The purple-colored reaction product of this assay is formed by the chelation of two molecules of BCA with one cuprous ion. This water-soluble complex exhibits a strong absorbance at 562nm that is nearly linear with increasing protein concentrations over a broad working range (20-2000µg/mL). The BCA method is not a true end-point method; that is, the final color continues to develop. However, following incubation, the rate of continued color development is sufficiently slow to allow large numbers of samples to be assayed together.The macromolecular structure of protein, the number of peptide bonds and the presence of four particular amino acids (cysteine, cystine, tryptophan and tyrosine) are reported to be responsible for color formation with BCA.2 Studies with di-, tri- and tetrapeptides suggest that the extent of color formation caused by more than the mere sum of individual color-producing functional groups.2 Accordingly, protein concentrations generally are determined and reported with reference to standards of a common protein such as bovine serum albumin (BSA). A series of dilutions of known concentration are prepared from the protein and assayed alongside the unknown(s) before the concentration of each unknown is determined based on the standard curve. If precise quantitation of an unknown protein is required, it is advisable to select a proteinstandard that is similar in quality to the unknown; for example, a bovine gamma globulin (BGG) standard (see Related Thermo Scientific Products) may be used when assaying immunoglobulin samples.Two assay procedures are presented. Of these, the Test Tube Procedure requires a larger volume (0.1mL) of protein sample; however, because it uses a sample to working reagent ratio of 1:20 (v/v), the effect of interfering substances is minimized. The Microplate Procedure affords the sample handling ease of a microplate and requires a smaller volume (10-25µL) of protein sample; however, because the sample to working reagent ratio is 1:8 (v/v), it offers less flexibility in overcoming interfering substance concentrations and obtaining low levels of detection.Preparation of Standards and Working Reagent (required for both assay procedures) A.Preparation of Diluted Albumin (BSA) StandardsUse Table 1 as a guide to prepare a set of protein standards. Dilute the contents of one Albumin Standard (BSA) ampule into several clean vials, preferably using the same diluent as the sample(s). Each 1mL ampule of 2mg/mL Albumin Standard is sufficient to prepare a set of diluted standards for either working range suggested in Table 1. There will be sufficient volume for three replications of each diluted standard.Table 1.

For the aboveexample, combine 50mL of Reagent A with 1mL of Reagent B.Note: When Reagent B is first added to Reagent A, turbidity is observed that quickly disappears upon mixing to yield a clear, green WR. Prepare sufficient volume of WR based on the number of samples to be assayed. The WR is stable for several days when stored in a closed container at room temperature (RT).Procedure Summary (Test-tube Procedure, Standard Protocol)Test-tube Procedure (Sample to WR ratio = 1:20)1.Pipette 0.1mL of each standard and unknown sample replicate into an appropriately labeled test tube.2.Add 2.0mL of the WR to each tube and mix well.3.Cover and incubate tubes at selected temperature and time:•Standard Protocol: 37°C for 30 minutes (working range = 20-2000µg/mL)•RT Protocol: RT for 2 hours (working range = 20-2000µg/mL)•Enhanced Protocol: 60°C for 30 minutes (working range = 5-250µg/mL)Notes:•Increasing the incubation time or temperature increases the net 562nm absorbance for each test and decreases both the minimum detection level of the reagent and the working range of the protocol.•Use a water bath to heat tubes for either Standard (37°C incubation) or Enhanced (60°C incubation) Protocol. Usinga forced-air incubator can introduce significant error in color development because of uneven heat transfer.4.Cool all tubes to RT.5.With the spectrophotometer set to 562nm, zero the instrument on a cuvette filled only with water. Subsequently, measurethe absorbance of all the samples within 10 minutes.Note: Because the BCA assay does not reach a true end point, color development will continue even after cooling to RT.However, because the rate of color development is low at RT, no significant error will be introduced if the 562nm absorbance measurements of all tubes are made within 10 minutes of each other.6.Subtract the average 562nm absorbance measurement of the Blank standard replicates from the 562nm absorbancemeasurement of all other individual standard and unknown sample replicates.7.Prepare a standard curve by plotting the average Blank-corrected 562nm measurement for each BSA standard vs. itsconcentration in µg/mL. Use the standard curve to determine the protein concentration of each unknown sample. Microplate Procedure (Sample to WR ratio = 1:8)1.Pipette 25µL of each standard or unknown sample replicate into a microplate well (working range = 20-2000µg/mL).Note: If sample size is limited, 10µL of each unknown sample and standard can be used (sample to WR ratio = 1:20).However, the working range of the assay in this case will be limited to 125-2000µg/mL.2.Add 200µL of the WR to each well and mix plate thoroughly on a plate shaker for 30 seconds.3.Cover plate and incubate at 37°C for 30 minutes.4.Cool plate to RT. Measure the absorbance at or near 562nm on a plate reader.Notes:•Wavelengths from 540-590nm have been used successfully with this method.•Because plate readers use a shorter light path length than cuvette spectrophotometers, the Microplate Procedure requires a greater sample to WR ratio to obtain the same sensitivity as the standard Test Tube Procedure. If higher 562nm measurements are desired, increase the incubation time to 2 hours.•Increasing the incubation time or ratio of sample volume to WR increases the net 562nm measurement for each well and lowers both the minimum detection level of the reagent and the working range of the assay. As long as allstandards and unknowns are treated identically, such modifications may be useful.5.Subtract the average 562nm absorbance measurement of the Blank standard replicates from the 562nm measurements ofall other individual standard and unknown sample replicates.6.Prepare a standard curve by plotting the average Blank-corrected 562nm measurement for each BSA standard vs. itsconcentration in µg/mL. Use the standard curve to determine the protein concentration of each unknown sample.Note: If using curve-fitting algorithms associated with a microplate reader, a four-parameter (quadratic) or best-fit curve will provide more accurate results than a purely linear fit. If plotting results by hand, a point-to-point curve is preferable to a linear fit to the standard points.A.Interfering substancesCertain substances are known to interfere with the BCA assay including those with reducing potential, chelating agents, and strong acids or bases. Because they are known to interfere with protein estimation at even minute concentrations, avoid the following substances as components of the sample buffer:Ascorbic Acid EGTA Iron Impure SucroseCatecholamines Impure Glycerol Lipids TryptophanCreatinine Hydrogen Peroxide Melibiose TyrosineCysteine Hydrazides Phenol Red Uric AcidOther substances interfere to a lesser extent with protein estimation using the BCA assay, and these have only minor (tolerable) effects below a certain concentration in the original sample. Maximum compatible concentrations for many substances in the Standard Test Tube Protocol are listed in Table 2 (see last page of Instructions). Substances were compatible at the indicated concentration in the Standard Test Tube Protocol if the error in protein concentration estimation caused by the presence of the substance was less than or equal to 10%. The substances were tested using WR prepared immediately before each experiment. Blank-corrected 562nm absorbance measurements (for a 1000µg/mL BSA standard + substance) were compared to the net 562nm measurements of the same standard prepared in 0.9% saline. Maximum compatible concentrations will be lower In the Microplate Procedure where the sample to WR ratio is 1:8 (v/v). Furthermore, it is possible to have a substance additive affect such that even though a single component is present at a concentration below its listed compatibility, a sample buffer containing a combination of substances could interfere with the assay.B.Strategies for eliminating or minimizing the effects of interfering substancesThe effects of interfering substances in the Pierce BCA Protein Assay may be eliminated or overcome by one of several methods. •Remove the interfering substance by dialysis or gel filtration.•Dilute the sample until the substance no longer interferes. This strategy is effective only if the starting protein concentration is sufficient to remain in the working range of the assay upon dilution.•Precipitate the proteins in the sample with acetone or trichloroacetic acid (TCA). The liquid containing the substance that interfered is discarded and the protein pellet is easily solubilized in ultrapure water or directly in the alkaline BCA WR.4A protocol detailing this procedure is available from our website. Alternatively, Product No. 23215 may be used (seeRelated Pierce Products).•Increase the amount of copper in the WR (prepare WR as 50:2 or 50:3, Reagent A:B), which may eliminate interference by copper-chelating agents.Note: For greatest accuracy, the protein standards must be treated identically to the sample(s).Related Thermo Scientific Products15041 Pierce 96-Well Plates, 100/pkg.15075 Reagent Reservoirs, 200/pkg.15036 Sealing Tape for 96-Well Plates, 100/pkg.23209 Albumin Standard Ampules, 2mg/mL, 10 × 1mL ampules, containing bovine serum albumin (BSA) 23208 Pre-Diluted Protein Assay Standards: Bovine Serum Albumin (BSA) Set, 7 × 3.5mL23212 Bovine Gamma Globulin Standard, 2mg/mL, 10 × 1mL ampules23213 Pre-Diluted Protein Assay Standards, (BGG) Set, 7 × 3.5mL aliquots23235 Pierce Micro BCA Protein Assay Kit, working range of 0.5-20µg/mL23236 Coomassie Plus (Bradford) Assay Kit, working range of 1-1500µg/mL23215 Compat-Able™ Protein Assay Preparation Reagent Set23250Pierce BCA Protein Assay Kit−Reducing Agent CompatibleAdditional InformationA.Please visit our website for additional information including the following items:•Frequently Asked Questions•Tech Tip protocol: Eliminate interfering substances from samples for BCA Protein AssayB.Alternative Total Protein Assay ReagentsIf interference by a reducing substance or metal-chelating substance contained in the sample cannot be overcome, try the Thermo Scientific Coomassie Plus (Bradford) Assay Kit (Product No. 23236), which is less sensitive to such substances.C.Cleaning and Re-using GlasswareExercise care when re-using glassware. All glassware must be cleaned and given a thorough final rinse with ultrapure water.D.Response characteristics for different proteinsEach of the commonly used total protein assay methods exhibits some degree of varying response toward different proteins. These differences relate to amino acid sequence, pI, structure and the presence of certain side chains or prosthetic groups that can dramatically alter the protein’s color response. Most protein assay methods use BSA or immunoglobulin (IgG) as the standard against which the concentration of protein in the sample is determined (Figure 1). However, if great accuracy is required, prepare the standard curve from a pure sample of the target protein.Typical protein-to-protein variation in color response is listed in Table 3. All proteins were tested at 1000µg/mL using the 30-minute/37°C Test Tube Protocol. The average net color response for BSA was normalized to 1.00 and the average net color response of the other proteins is expressed as a ratio to the response of BSA.Figure 1: Typical color response curves for BSA and BGG using the Standard Test Tube Protocol (37°C/30-minute incubation).

化学名称:[[1R,2R,3aS,9aS)-2,3,3a,4,9,9a-六氢-2-羟基-1-[(3S)-3-羟基辛烷基]-1H-苯并[f]茚-5-基]氧基]乙酸分子式:C23H33NaO5分子量:390.52辅料:枸橼酸钠二水合物、盐酸、间甲酚、氢氧化钠、氯化钠、注射用水。
【瑞莫杜林性状】瑞莫杜林为无色至微黄色的澄明液体。
【瑞莫杜林适应症】瑞莫杜林用于治疗肺动脉高压(PAH,WHO分类1),以减轻运动引起的相关症状。
在建立瑞莫杜林疗效的研究中,研究受试者包括NYHA 功能分级II~IV级的原发性和遗传性肺动脉高压(58)、与先天性体肺循环分流相关的肺动脉高压(23)以及与结缔组织疾病相关的肺动脉高压(19)。
【瑞莫杜林规格】20ml:20mg【瑞莫杜林用法用量】瑞莫杜林用20ml玻璃瓶包装,含有20mg曲前列尼尔(1mg/ml)。
瑞莫杜林输注前需用注射用水或0.9NaCl注射液稀释。
瑞莫杜林的给药方式为皮下或静脉注射给药。
首次接受前列环素输注治疗患者的初始剂量瑞莫杜林只能连续皮下(SC)或静脉(IV)输注。
皮下输注是给药路径。
但是,如果因为注射部位严重疼痛或反应而不能耐受皮下给药,也可经中心静脉导管给药。
初始输注速率为1.25ng/kg/min。
如果由于全身效应不能耐受初始剂量,应将注射速率降低至0.625ng/kg/min。
剂量调整长期剂量调整的目标是确定曲前列尼尔的剂量,使其可改善肺动脉高压症状,同时减少瑞莫杜林的其他药理效应(头痛、恶心、呕吐、坐立不安、焦虑以及输注部位疼痛或反应)。
根据临床疗效进行剂量调整。
在治疗的前四周,输注速率的增加值为每周1.25ng/kg/min,之后为每周2.5ng/kg/min。

据报道我国城镇和乡村人群抽样调查结果表明,年发病率分别为219/10万和185/10万,死亡率为116/10万和141.8/10万,且趋年轻化。
我国每年新发脑卒中病人约150~200万人,其中缺血性脑卒中约占脑卒中病例的60~80%。
1992年我国城乡人口死亡原因中,脑卒中均排在第二位,占死亡总人数的21.13%和16.18%。
北京地区缺血性脑卒中的比例1999年达81.6%。
我国死于脑血管病多于死于心脏病及癌症,位于三大死因之首。
脑卒中不但以高发病率、高死亡率、高致残率危害人民健康,而且在存活下来的占80%的中风患者中,仅有10%左右能完全恢复正常功能,绝大多数患者都留有偏瘫,失语等后遗症,从而对社会及家庭造成极严重的负担。
其它国家的状况也大致相似。
因此对脑血管病的防治为全社会所关注。
各国药物学家和医疗专家及各方力量(政府、社会团体)将研发防治脑血管病的药物视为迫切使命,但国内外尚无理想的治疗药物。
我们在前期研究抗轻、中度急性缺血性脑卒中新药消旋3-正丁基苯酞(dl-NBP,商品名“恩必普”)基础上,利用前药原理深入研发出具有自主知识产权的前药消旋2-(α-羟基戊基)苯甲酸钾(dl-PHPB)原料药、片剂和冻干剂,以克服丁苯酞存在的不足,增加治疗急性缺血性脑血管病药物的新品种、扩大适应症,适用于从轻度至重度急性缺血性脑血管病患者的治疗。
