Cell Proliferation Induced by IL‑1 beta/IL‑1F2 and Neutralization by Human IL‑1 beta/IL‑1F2 Antibody.

Recombinant Human IL-1 beta/IL-1F2 (Catalog # 201-LB) stimulates proliferation in the the D10.G4.1 mouse helper T cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human IL-1 beta/IL-1F2 (0.05 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human IL-1 beta/IL-1F2 Monoclonal Antibody (Catalog # MAB601). The ND₅₀ is typically 0.05-0.2 µg/mL.

Detection of Human IL-1 beta/IL-1F2 by ELISA

Effect of A1AT on whole blood IL-1 beta release. IL-1 beta production in whole blood cultures in response to LPS (1.0 μg/ml) was performed in the presence of endogenous A1AT (i.e., undiluted) or exogenously added A1AT (2 mg/ml) in blood diluted 1:32 with RPMI. Whole blood cultures were incubated for 18 h. After incubation, plasma supernatants were removed, and IL-1 beta quantified by ELISA and expressed as mean ± SD for three donors. The diluted sample result was corrected for the dilution. NS indicates no significant difference.
