Serial dilutions or titrations of analytes and other assay components are key to assembling biochemical and cell-based assays in drug discovery and life science research. These assays are used, for example, in assay development to determine appropriate concentration ranges, in secondary screening to evaluate pharmacological response, and in early Absorption, Distribution, Metabolism, Excretion and Toxicity (ADMET) to determine toxicological effects. The ability to rapidly and accurately produce dilution curves in an automated system is essential to improving assay throughput and quality. The JANUS ® Automated Workstation equipped with the Modular Dispense Technology ® (MDT) permits users to rapidly assemble microplate assays with a variety of 96- and 384-well dispense tools.Optional JANUS MDT Serial Dilution Tools (SDT) enable users to perform analyte pipetting in either a single row or column pattern using a single row or column of disposable tips from a standard box of tips. Moreover, Modular Dispense Technology permits rapid, "on-the-fly" swapping between standard 96- or 384-well heads and these serial dilution heads.Serial Dilution Tools deliver maximum flexibility in the liquid handling processes. These tools have the same dynamic pipetting range (0.5 μL – 235 μL) as the standard MDT pipetting heads, are used with the same disposable tip options, and accommodate 96-, 384-, and 1536-well plate formats.Application Workstationsa p p l i c a t i o n n o t eSerial Dilutions on theJANUS Automated Workstation with Modular Dispense T echnologyAuthorsL ee Brady, Dianne Brazzill, Jim Fronek, and Steven Liebold1P erkinElmer, Inc.Downers Grove, IL 60515 USAThis application note presents case studies outlining perfor-mance capabilities, as well as applications-specific results, ofthe Serial Dilution Tools. This data includes pipetting accuracyand precision for a range of volumes, row and column configu-rations, plate types, and disposable tip sizes. Experimental datafrom AlphaLISA® standard curves constructed using the toolsdemonstrate enhanced versatility.Case Study 2: Liquid Serial DilutionPerformance AnalysisMaterials and Methods: Fully automated serial dilutions wereperformed using the JANUS Automated Workstation, a P235Row/Column Serial Dilution Tool and disposable P235 pipettetips. A stock solution of 10 nM fluorescein isothiocyanate(FITC, 1X phosphate buffered saline, pH 9.0) was serially dilut-ed (two-fold) with 80% DMSO to a final concentration of1/64th the stock concentration. Dilutions were performed onthree replicate plates. Controls included positive (undiluted 10nM FITC dye) and negative (80% DMSO buffer).Fluorescence readings were obtained using a PerkinElmerEnvision Multilabel Pate Reader for single 96-well plate(row format) serial dilutions. Results were plotted as observedfluorescence (relative fluorescence units, RFU) versus expectedRFU (based upon the signal obtained with 10 nM FITC).Results and Discussion: In order to evaluate the efficiencyand reproducibility of an analyte pipetting, we used a modelfluorescence-based assay. Fluorescent tags are widely utilizedin applications such as nucleic acid and protein quantification,cellular metabolism and separation technologies. Theseprocedures often require serially diluted gradients to serve asstandard curves, or in the case of enzymatic reactions, optimi-zation of enzyme/substrate ratios. The use of fluorescent tags Case Study 1: Pipetting Precision and AccuracyMaterials and Methods: The pipetting accuracy and precisionwere evaluated for each of the Serial Dilution Tools (P30 row/column, P50 row, P50 column, and P235 row/column) installedon a JANUS Automated Workstation. Serial Dilution Tools weretested in either row and/or column format for a range of volumesusing corresponding PerkinElmer disposable tip sizes.Pipetting accuracy was evaluated gravimetrically using a MettlerToledo AT 261 Delta Range balance under controlled tempera-ture and humidity conditions. Destination plates were preparedwith known volumes of 80% DMSO filled using a PerkinElmerFlexDrop™ IV EX Precision Reagent Dispenser. Fixed volumes of2% Orange-G dye solution (80% DMSO, Sigma-Aldrich, St.Louis, MO) were pipetted into destination plates with the SDT.Results for each condition were reported as percent accuracy,averaged across triplicate 96- (Nunc clear 96-well flat bottom),or 384- (Greiner Bio One clear 384-well flat bottom) well plates.Pipetting precision evaluations utilized the above-mentionedOrange-G dye-containing plates. Immediately following gravi-metric accuracy measurements, dispensed Orange-G dye plateswere loaded, and absorbance readings were obtained, using aPerkinElmer EnVision® Multilabel Plate Reader. Pipetting precision(% CV) was determined using optical density values across eachof the triplicate (N=3) 96- or 384-well plates.Results and Discussion: The ability to dispense analytes witha high level of precision and accuracy is critical for any application.We evaluated the JANUS Serial Dilution Tools to demonstratepipetting accuracy and precision in either row and/or columnpipetting format(s) at common volume ranges and plate types.Results indicated that the Serial Dilution Tools performed withvery high accuracy and precision (Table 1).Table 1. Examples of Summary of Serial Dilution Tool sample pipettingperformance data.23offers a quantitative method of evaluating targeted molecules and provides a convenient and cost-effective methodology for evaluating sample protocols prior to introducing more expen-sive or scarce reagents.The SDT P235 was used to serially dilute FITC fluorescent dye in row format. Results demonstrate a highly reproducible pipetting pattern for serial dilutions (Figure 1). Reproducibility of automated procedures allows users to perform complex dilution sequences, with reduced potential for human error or potential loss of valuable compound in repeated experiments.Case Study 3: Performance with Immunoassay AnalytesMaterials and Methods: AlphaLISA ® Insulin and vascular endothelial growth factor (VEGF) immunoassay kits wereobtained from PerkinElmer BioSignal (Montreal, Canada). Serial dilutions of analyte standards containing insulin or VEGF were performed automatically on a JANUS with a P50 Column SDT, and manually, using a multichannel pipette.AlphaLISA Insulin Immunoassay Serial Dilutions . A column of 8 wells (PerkinElmer half-area white OptiPlates) containing insulin stock standards (10 μUnits/μL) was serially diluted two-fold (25 μL + 25 μL) in column format with AlphaLISA diluent buffer. AlphaLISA VEGF Immunoassay Serial Dilutions . In an identical manner as the above-mentioned insulin immunoassay, a stock concentration of vascular endothelial growth factor (VEGF) standard (1.5 x 10E-5g/ml) was serially diluted in column for-mat with AlphaLISA diluent buffer.Results and Discussion: As an example of partial plate pro-cessing capability, we used the SDT to perform single column pipetting to generate serially diluted analyte standard curves for AlphaLISA (Amplified Luminescent Proximity Homogeneous Assay) immunoassays for insulin and VEGF. AlphaLISA is a no-wash ELISA assay alternative developed by PerkinElmer [1]. Insulin and VEGF are two common biomarkers whose concen -trations are monitored for research diagnostic and screening applications.The JANUS Automated Workstation equipped with a P50Column SDT was used to effectively construct standard curves for both analytes. Manually generated standard curves com-pared favorably with those automated using the SDT (Figure 2). Results were consistent with previously reported AlphaLISA data generated for insulin and VEGF standard curves per -formed using a JANUS 8-tip Varispan™ pipetting arm [3-4].ConclusionsJANUS Modular Dispense Technology Serial Dilution Tools pro-vide an adaptable array of row and column pipetting options for standard curves, serial and direct dilutions, and discrete row / column sample additions. These pipetting capabilities are highly utilized in a number of areas including compound library screening in drug discovery, as well as in assay development and high density combinatorial assays.Figure 2. Serially diluted standard curves for AlphaLISA detection of vascular endothelial growth factor (VEGF, A) and insulin (B) using the P50 Column Serial Dilution Tool or an 8-channel manual pipette. Data are the mean of 8 replicate wells per column.Figure 1. Reproducibility of fluorescence dye serial dilutions . Two-fold serial dilutions of FITC (10 nM stock diluted to 1/64th ) were performed in row format using the JANUS MDT P235 Row/Column Serial Dilution Tool. Data are the mean ± SEM for each data point among the three replicate plates. Observed relative fluorescence units (RFU) were plotted against the expected RFU values based upon fluorescence of 10 nM FITC. Linear regression of these values indicate tight correlation with expected RFU values.For a complete listing of our global offices, visit /ContactUsCopyright ©2009, PerkinElmer, Inc.
