ElisaRSR TM TRAb 2nd Generation TSH Receptor Autoantibody2nd Generation ELISA Kit -Instructions for useRSR LimitedParc Ty Glas, Llanishen,Cardiff CF14 5DU United KingdomTel.: +44 29 2068 9299 Fax: +44 29 2075 7770 Email: Website: EC REP Advena Ltd. Tower Business Centre, 2nd Flr., Tower Street, Swatar, BKR 4013 Malta.INTENDED USEThe RSR TSH receptor (TSHR) autoantibody (TRAb) ELISA kit is intended for use by professional persons only for the quantitative determination of TRAb in human serum. Hyperthyroidism in Graves’ disease is due to the presence of autoantibodies to the TSHR and measurement of these autoantibodies can be useful in disease diagnosis and management. REFERENCESJ. Bolton et alMeasurement of thyroid stimulating hormone receptor autoantibodies by ELISAClin. Chem. 1999 45: 2285-2287K. KamijoTSH receptor antibody measurement in patients with various thyrotoxicosis and Hashimoto’s thyroiditis: a comparison of two two-step assays, coated plate ELISA using porcine TSH receptor and coated tube radioassay using human recombinant TSH receptorEndocrine Journal 2003 50:113-116B. Rees Smith et alA new assay for thyrotropin receptor autoantibodiesThyroid 2004 14: 830-835ASSAY PRINCIPLEIn RSR’s TRAb ELISA, TRAb in patients’sera, calibrators and controls are allowed to interact with TSHR coated onto ELISA plate wells. After a 2 hour incubation, the samples are discarded leaving TRAb bound to the immobilised TSHR. TSH-Biotin is added in a 2nd incubation step, where it interacts with immobilised TSHR which have not been blocked by the bound TRAb from patient sera, calibrators or controls. The amount of TSH-Biotin bound to the plate is then determined in a 3rd incubation step by addition of Streptavidin Peroxidase (SA-POD), which binds specifically to Biotin. Excess unbound SA-POD is then discarded and the addition of the peroxidase substrate 3,3’,5,5’–tetramethylbenzidine (TMB) results in the formation of a blue colour. This reaction is stopped by the addition of stop solution causing the well contents to turn from blue to yellow. The absorbance of the yellow reaction mixture at 450nm is then read using an ELISA plate reader. A lower absorbance indicates the presence of TRAb in a test sample as TRAb inhibits the binding of TSH-Biotin to TSHR coated plate wells. The measuring range is 1 – 40 IU/L (NIBSC 08/204). STORAGE AND PREPARATION OF TEST SERUM SAMPLESSera to be analysed should be assayed soon after separation or stored, preferably in aliquots, at or below –20o C. 150 μL is sufficient for one assay (duplicate 75 μL determinations). Repeated freeze thawing or increases in storage temperature must be avoided. Incorrect storage of serum samples can lead to loss of TRAb activity. Do not use lipaemic or haemolysed serum samples. Do not use plasma in the assay. When required, bring test sera to room temperature (20 –25ºC) and mix gently to ensure homogeneity. Centrifuge the serum prior to assay (preferably for 5 minutes at 10-15,000 rpm in a microfuge) to remove any particulate matter. Please do not omit this centrifugation step for sera that are cloudy or contain particulates.IVDMATERIALS REQUIRED AND NOT SUPPLIED Pipettes capable of dispensing 50 μL, 75 μL and 100μL.Means of measuring out various volumes to reconstitute or dilute reagents.Pure water.ELISA Plate reader suitable for 96 well formats and capable of measuring at 450nm.ELISA Plate shaker, capable of 500 shakes/min (not an orbital shaker).ELISA Plate cover.PREPARATION OF REAGENTS SUPPLIEDStore unopened kits and all kit components (A-K) ato ASSAY PROCEDUREAllow all reagents and test samples to stand at room temperature (20-25o C) for at least 30 minutes before use. A repeating Eppendorf type pipette is recommended for steps 1, 5, 8, 10 and 11. Duplicate determinations are strongly recommended for test sera, calibrators and controls.RESULT ANALYSISA calibration curve can be established by plotting calibrator concentration on the x-axis (log scale) against the absorbance of the calibrators on the y-axis (linear scale). The TRAb concentrations in patients’ sera can then be read off the calibration curve [plotted at RSR as a spline log/lin curve (smoothing factor = 0)]. The negative control can be assigned a value of 0.1 to assist in computer processing of assay results. Other data reduction systems can be used. Results can also be expressed as inhibition (%I) of TSH binding calculated using the formula;⎪⎪⎭⎫ ⎝⎛nm 450 absorbance (D1) control negative nm 450 at absorbance sample test - 1 x 100Samples with high TRAb concentrations can be diluted in kit negative control (D1). For example, 20 μL of sample plus 180 μL of negative control to give a 10x dilution. Other dilutions (e.g. 100x) can be prepared from a 10x dilution or otherwise as appropriate. Some sera will not dilute in a linear way and we suggest that the dilution giving a value closest to 50% inhibition is used for calculation of TRAb concentration.TYPICAL RESULTS (example only, not for use inThis cut off has been validated at RSR. However each laboratory should establish its own normal and pathological reference ranges for TRAb levels. Also it is recommended that each laboratoryinclude its own panel of control samples in the assay.CLINICAL EVALUATION Clinical Specificity154 Sera from healthy blood donors were assayed in the RSR TRAb ELISA kit. 152 (99%) were identified as being negative for TRAb.Clinical Sensitivity50 Sera from p atients diagnosed with Graves’ disease were assayed using the RSR TRAb ELISA kit. 49 (98%) were identified as being positive for TRAb. 1 sample (2%) was identified as being within the equivocal range.Functional SensitivityA plot of inter assay CV against IU/L indicates a 20% CV occurring at 0.60 IU/L.Lower Detection LimitThe kit negative control was assayed 32 times and the mean and standard deviation calculated. The lower detection limit at 2 standard deviations was 0.21 IU/L.Clinical AccuracyAnalysis of sera from patients with autoimmune diseases other than Graves’ disease indicated no interference from autoantibodies to thyroglobulin; thyroid peroxidase; glutamic acid decarboxylase; 21-hydroxylase; acetylcholine receptor; dsDNA or from rheumatoid factor. InterferenceNo interference was observed when samples were spiked with the following materials; haemoglobin at 5 mg/mL; bilirubin at 0.2 mg/mL; Intralipid up to 30 mg/mL, human LH up to 10 u/mL; hCG up to 160 u/mL; human FSH up to 70 u/mL and human TSH up to 3 u/L.SAFETY CONSIDERATIONSStreptavidin Peroxidase (SA-POD)Signal word: WarningHazard statement(s)H317: May cause an allergic skin reaction Precautionary statement(s)P280: Wear protective gloves/protective clothing/ eye protection/face protectionP302 + P352: IF ON SKIN: Wash with plenty of soap and waterP333 + P313: If skin irritation or rash occurs: Get medical advice/attentionP362 + P364: Take off contaminated clothing and wash it before reusePeroxidase Substrate (TMB)Signal word: DangerHazard statement(s)H360: May damage fertility or the unborn child Precautionary statement(s)P280: Wear protective gloves/protective clothing/ eye protection/face protectionP308 + P313: IF exposed or concerned: Get medical advice/attention This kit is intended for in vitro use by professional persons only.

促甲状腺激素(TSH)检测丨ELISA试剂盒解决方案促甲状腺激素(TSH)是由腺垂体分泌的激素,腺垂体分泌促甲状腺激素,一方面受下丘脑分泌的促甲状腺激素释放激素(TRH)的促进性影响,另一方面又受到甲状腺激素反馈性的抑制性影响,二者互相拮抗,它们组成下丘脑-腺垂体-甲状腺轴。
促甲状腺激素主要负责调节甲状腺细胞的增殖、甲状腺血液供应以及甲状腺激素的合成和分泌,在维持正常甲状腺功能中起最重要的调节作用。
垂体本身的疾病可以直接影响到TSH 的合成和释放。
当甲状腺本身原因导致甲状腺激素合成和分泌异常时,也可影响到垂体TSH 的分泌和血清TSH水平。
同样,下丘脑疾病影响到TRH分泌时也会影响垂体的TSH的分泌和血清TSH水平。
促甲状腺激素(TSH)检测是查明甲状腺功能的初筛试验。
游离甲状腺浓度的微小变化就会带来TSH浓度向反方向的显著调整。
1.血清TSH升高:常见于原发性甲状腺功能减退症、TSH分泌瘤、缺碘性地方性甲状腺肿、甲状腺激素抵抗综合征等。
2.血清TSH降低:常见于原发性甲状腺功能亢进症,TSH基因突变,各种垂体性疾病(如垂体腺瘤、垂体炎症、垂体出血性疾病或损伤性疾病等)影响TSH细胞功能,各种甲状腺炎的损伤期,以及临床应用大剂量糖皮质激素等。

该测定法对促甲状腺激素(TSH)的检测具有很高的灵敏度和出色的特异性。
且在促甲状腺激素(TSH)与类似物之间未观察到明显的交叉反应或干扰。
检测原理:该试剂盒基于竞争性酶联免疫吸附测定技术。
将抗体预包被到96孔板上。

在预先包被的抗体上,生物素标记的TSH与未标记的TSH之间发生竞争性抑制反应。
然后加入结合了HRP的试剂,并孵育整个平板。
在每个阶段使用洗涤缓冲液去除未结合的物质。
