Product Overview
Human IL-2 ELISA Kit is a ready-to-use immunoassay kit, specifically designed to quantitate natural and recombinant human IL-2 that is present in biological samples, such as human serum, plasma, and cell culture supernatants. Our ELISA Kit provides several benefits:
- Standards to calibrate with NIBSC/WHO standards for comparable results.
- Fully validation in biologic samples for detection range, sensitivity, inter- and intra-plate CV, recovery, dilution linearity, specificity, and matrix effects to ensure reliable results according to ICH M10 guideline.
- High-quality antibody pairs and protein standards, along with rigorous quality control, to guarantee consistent results across different batches.
- Simplified and straightforward protocols and ready-to-use reagents to save assay time.

Performance Data
Typical Data
Please refer to DS document for the assay protocol.
For each experiment, a standard curve needs to be set for each microplate, and the specific OD value may vary depending on different laboratories, testers, or equipment. The following example data is for reference only. The sample concentration was calculated based on the results of the standard curve. The minimum detectable concentration of IL-2 is less than 5.0pg/mL.
Sample Values
Serum Sample: two hundred and forty samples from healthy volunteers were tested for the presence of human IL-2 concentration in the assay. One hundred and eighty-four samples were detectable. No medical histories were available for the donors used in this study.
Matrix Effect
Six types of materials were tested to observe if there were matrix effect (interference). If the concentration of bilirubin (simulated jaundice) is less than 20 mg/dL, the concentration of hemoglobin (simulated hemolysis) is less than 3500 mg/dL, the concentration of triglyceride (simulated lipid blood) is less than 2.0 g/L, Heparin concentration is less than 40U/mL, EDTA concentration is less than 4 mg/mL, and Sodium Citrate Plasma concentration is less than 40 mg/mL, testing results will not be affected.
Dilution Linearity
High concentrations of human IL-2 serum samples were diluted with 1:2, 1:4, and 1:8 ratios for gradient dilution to evaluate the linearity of the assay. In the serum samples, the average detection rate of IL-2 was 97.38%.
Intra-Assay Statistics
Ten replicates of each of three samples containing different IL-2 concentrations were tested in one assay. Acceptable criteria: CV＜10%.
Inter-Assay Statistics
Three samples containing different concentrations of IL-2 were tested in the independent assays. Acceptable criteria: CV<15%.
Recovery
IL-2 was spiked into five human serum samples, and then analyzed. The average recovery of IL-2 for serum samples is 97.58%.
