Example of IL-1beta standard curve with the standard prepared in Sample Diluent NS.

Example of IL-1beta standard curve with the standard prepared in Sample Diluent 25BP. Background-subtracted data values (mean +/- SD) are graphed.

Titration of PBMC+PHA supernatant within the working range of the assay. Background subtracted data from duplicate measurements are plotted.

Human peripheral blood cells (1x106 cells/mL) were cultured in RPMI media supplemented with 10% fetal calf serum, 100 U/mL penicillin, and 100 µg/mL streptomycin sulfate. Cells were cultured unstimulated or stimulated with 10 µg/mL PHA. Conditioned media was harvested after 48 hours, aliquoted and assayed for endogenous IL-1 beta levels.
