Regulatory Status Legend
Any use of products other than the permitted use without the express written authorization of Becton, Dickinson and Company is strictly prohibited.
Description
The OptEIA™ Set for mouse interleukin-10 (IL-10) contains the components necessary to develop enzyme-linked immunosorbent assays (ELISA) for natural or recombinant mouse IL-10 in serum, plasma, and cell culture supernatants. Sufficient materials are provided to yield approximately 20 plates of 96-wells if the recommended storage, materials, buffer preparation, and assay procedure are followed as specified in this package.
Assay Optimization
BD OptEIA™ Sets allow flexible assay design to fit individual laboratoryneeds. To design an immunoassay with different sensitivity and dynamic range, the following parameters can be varied: Capture, Detection Antibody titers, Incubation time, Incubation temperature, Assay Diluent formulation, Buffer pH, ionic strength, protein concentration, Type of substrate, Washing technique (i.e.,number of wash repetitions and soak times).
Standardization: This immunoassay is calibrated against purified Baculovirus-expressed recombinant mouse IL-10.

Specimen Collection and Handling: Specimens should be clear, non-hemolyzed and non-lipemic.
Cell culture supernatants: Remove any particulate material by centrifugation and assay immediately or store samples at ≤ -20°C. Avoid repeated freeze thaw cycles.
Serum: Use a serum separator tube and allow samples to clot for 30 minutes, then centrifuge for 10 minutes at 1000 x g. Remove serum and assay immediately or store samples at ≤ -20° C. Avoid repeated freeze-thaw cycles.
Plasma: Collect plasma using citrate, EDTA, or heparin as anticoagulant. Centrifuge for 10 minutes at 1000 x g within 30 minutes of collection. Assay immediately or store samples at ≤ -20° C. Avoid repeated freeze-thaw cycles.
Standards Preparation and Handling
1. Reconstitution: After warming lyophilized standard to room temperature, carefully open vial to avoid loss of material. Reconstitute lyophilized standard with 1.0 mL of deionized water to yield a stock standard. Allow the standard to equilibrate for at least 15 minutes before making dilutions. Vortex gently to mix.
2. Storage/ handling of reconstituted standard: After reconstitution, immediately aliquot standard stock in polypropylene vials at 50 μl per vial and freeze at -80°C for up to 6 months. If necessary, store at 2-8° C for up to 8 hours prior to aliquotting/freezing. Do not leave reconstituted standard at room temperature.
3. Standards Preparation for Assay:
a. Prepare a 2000 pg/mL standard from the stock standard. Vortex to mix. (See dilution instructions on Instruction/Analysis Certificate.)
b. Add 300 μL Assay Diluent to 6 tubes. Label as 1000 pg/mL, 500 pg/mL, 250 pg/mL, 125 pg/mL, 62.5 pg/mL, and 31.3 pg/mL.
c. Perform serial dilutions by adding 300 μL of each standard to the next tube and vortexing between each transfer. Assay Diluent serves as the zero standard (0 pg/mL).
Working Detector Preparation
(Note: One-step incubation of Biotin/SAv reagents.) Add required volume of Detection Antibody to Assay Diluent. Within 15 minutes prior to use, add required quantity of Enzyme Reagent, vortex or mix well. For recommended dilutions, see lot-specific Instruction/Analysis Certificate. For a full 96-well plate, prepare 12 mL of Working Detector. Discard any remaining Working Detector after use.
Detailed Assay Procedure
1. Coat microwells with 100 μL per well of Capture Antibody diluted in Coating Buffer. For recommended antibody coating dilution, see lot-specific Instruction/Analysis Certificate. Seal plate and incubate overnight at 4° C.
2. Aspirate wells and wash 3 times with ≥ 300 μL/well Wash Buffer. After last wash, invert plate and blot on absorbent paper to remove any residual buffer.
3. Block plates with ≥ 200 μL/well Assay Diluent. Incubate at RT for 1 hour.
4. Aspirate/wash as in step 2.
5. Prepare standard and sample dilutions in Assay Diluent. See"Standards Preparation and Handling".
6. Pipette 100 μL of each standard, sample, and control into appropriate wells. Seal plate and incubate for 2 hours at RT.
7. Aspirate/ wash as in step 2, but with 5 total washes.
8. Add 100 μL of Working Detector (Detection Antibody + SAv-HRP reagent) to each well. Seal plate and incubate for 1 hour at RT.
9. Aspirate/ wash as in step 2, but with 7 total washes.
10. Add 100 μL of Substrate Solution to each well. Incubate plate (without plate sealer) for 30 minutes at room temperature in the dark.
11. Add 50 μL of Stop Solution to each well.
12. Read absorbance at 450 nm within 30 minutes of stopping reaction. If wavelength correction is available, subtract absorbance at 570 nm from absorbance 450 nm.

10. Add 50 μL Stop Solution to each well. Read at 450 nm within 30 min with λ correction 570 nm.
Calculation of Results
Calculate the mean absorbance for each set of duplicate standards, controls and samples. Subtract the mean zero standard absorbance from each.
Plot the standard curve on log-log graph paper, with IL-10 concentration on the x-axis and absorbance on the y-axis. Draw the best fit curve through the standard points.
To determine the IL-10 concentration of the unknowns, find the unknown's mean absorbance value on the y-axis and draw a horizontal line to the standard curve. At the point of intersection, draw a vertical line to the x-axis and read the IL-10 concentration. If sampleswere diluted, multiply the IL-10 concentration by the dilution factor.
Computer data reduction may also be employed, utilizing log-log regression analysis.

Limitations of the Procedure
· Samples that generate absorbance values higher than the standard curve should be diluted with Standard Diluent and re-assayed.
· Interference by drug metabolites, soluble receptors, or other binding proteins in specimens has not been thoroughly investigated. The possibility of interference cannot be excluded.
· BD OptEIA™ Sets are intended for use as an integral unit. Do not mix reagents from different Set batches. Reagents from other manufacturers are not recommended for use in this Set.
