The G265-8 antibody reacts with both the 72 and 77 amino acid forms of human interleukin-8 (IL-8). The immunogen used to produce the G265-8 hybridoma was E. coli-expressed recombinant human IL-8. Expression of IL-8 by stimulated CD14+ human monocytes. Human PBMC were stimulated for 6 hours with LPS (10 ng/mL final concentration) in the presence of GolgiStop™ (2 μM final concentration, Cat. No. 554724). The PBMC were harvested, stained with FITC-mouse anti-human CD14 antibody (FITC-M5E2, Cat. No. 555397), fixed, permeabilized, and subsequently stained with 0.25 μg of PE-mouse anti-human IL-8 antibody (PE-G265-8, Cat. No. 554720) following the BD Pharmingen staining protocol (left panel). The data reflect gating on monocytes, based on forward and side scattered light signals. To demonstrate specificity of staining, the binding of PE-G265-8 was blocked by the preincubation of the conjugated antibody with recombinant human IL-8 (0.25 μg, Cat. No. 554609, center panel), and by preincubation of the fixed/permeabilized cells with unlabelled G265-8 antibody (2.5 μg, Cat. No. 554717, right panel) prior to staining with the PE-G265-8 antibody. The quadrant markers for the bivariate dot plots were set based on the autofluorescence control, and verified with the recombinant cytokine blocking (center panel) and unlabelled antibody (right panel) blocking specificity controls.
