Assay Method Information

Assay Name:   IL-2 ELISA Assay
Description:  Primary T cell stimulation and IL2 ELISA: Human primary T cells (100,000 cells per well) were pre-incubated with or without test compound in Yssel's medium for 1 hour at 37° C. Cells were then stimulated by transferring them to round-bottom 96-well plates pre-coated with 1 μm/ml αCD3 and 5 μg/ml αCD28. For counter assay, cells were instead stimulated by adding 8× stock solutions of PMA and ionomycin in Yssels (for final concentrations of 0.5 ng/ml PMA and 0.1 uM ionomycin, both from Calbiochem). Cells were incubated at 37° C. for 24 hours before 100 μL supernatants were harvested for quantification of IL-2 by ELISA using Human IL-2 Duoset ELISA Kit from R and D Systems, Cat. # DY202E.
