The 2A2 antibody reacts with both the 72 and 77 amino acid forms of human IL-8. The immunogen used to produce the 2A2 hybridoma was E. coli-expressed recombinant human IL-8 (77 amino acid form).
This antibody has been reported to show no cross-reactivity with the following cytokines or chemokines: Human IL-1α, IL-1β, IL-2, IL-3, IL-4, IL-5, IL-6, IL-7, IL-12 (p40 or p70), IL-13, IL-15, eotaxin, GRO, IFN- γ, MCP-1, MCP-2, MCP-3, MIP-1α, MIP-1β, NAP-2, PF4, RANTES, SCF, TNF, LT-α.
Neutralization: Investigators are advised that this material is not routinely tested for the Neutralization application and are highly encouraged to both titrate this material and include appropriate controls in relevant experiments. This antibody has previously been reported to be useful for the neutralization of recombinant human IL-8 when measured with a calcium flux assay using 250 ng/mL recombinant human IL-8 (Cat. No. 554609) to stimulate calcium mobilization in 1x10^7 cells/mL human lysed whole blood as indicator cells. Preincubation of the antibody with recombinant human IL-8 can neutralize calcium mobilization with the following representative ranges:
50% Neutralization (ND50) at 8 - 10 μg/mL
> 95% Neutralization at 150 - 500 μg/mL
