Detection of CXCR1/IL-8 RA antibody in Human Blood Granulocytes antibody by Flow Cytometry.

Detection of CXCR1/IL‑8 RA in Human Blood Granulocytes by Flow Cytometry.

Human peripheral blood granulocytes were stained with Mouse Anti-Human CXCR1/IL-8 RA Monoclonal Antibody (Catalog # MAB330, filled histogram) or isotype control antibody (Catalog # MAB003, open histogram), followed by Phycoerythrin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0102B).
Chemotaxis Induced by CXCL8/IL‑8 and Neutralization by Human CXCR1/IL‑8 RA Antibody.

Chemotaxis Induced by CXCL8/IL‑8 and Neutralization by Human CXCR1/IL‑8 RA Antibody.

Recombinant Human CXCL8/IL-8 (Catalog # 208-IL) chemoattracts the BaF3 mouse pro-B cell line transfected with human CXCR1 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Human CXCL8/IL-8 (1 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human CXCR1/IL-8 RA Monoclonal Antibody (Catalog # MAB330). The ND50 is typically 0.4-2.0 µg/mL.

IL‐8/CXCR1 contributes to stemness in vitro. (A) Effect on sphere formation of single agent or combination treatment with human recombinant IL‐8, anti‐CXCR1 antibody and/or repertaxin for Caki‐1 (Kruskal–Wallis test, n = 5). (B) Effect on sphere formation of single agent or combination treatment with human recombinant IL‐8, anti‐CXCR1 antibody and repertaxin for 769P cells (Kruskal–Wallis test, n = 5). (C) Flow cytometry analysis of the SP and the CXCR1+ cell compartment upon repertaxin treatment in the spheres derived from Caki‐1. (D) Histograms showing decreased SP and CXCR1+ cells upon repertaxin treatment. The yellow area indicates number of events with verapamil treatment. The red area shows CSC and CXCR1+ populations in the untreated sample. The blue area displays the remaining number of events after repertaxin treatment.

Detection of CXCR1/IL-8RA by Western Blot

Detection of CXCR1/IL-8RA by Western Blot

IL-8 as a partial inducer of MMP9 in ESCC cells. (A): ELISA quantification of IL-8 in culture supernatants of ESCC cells after direct co-culture with macrophages. Directly co-cultured ESCC cells secreted more IL-8 than monocultured counterparts. (B): Western blot revealed the expression of known IL-8 receptors, CXCR1 (45 kDa, monomer; 80–90 kDa, dimer and their glycosylated forms) and CXCR2 (41 kDa) in TE-9, TE-10, and TE-11 cell lines. (C,D): Treatment with rhIL-8 (100 ng/mL, for 24 h) upregulated MMP9 mRNA expression in all three ESCC cell lines (C) but only triggered MMP9 secretion from TE-10 (D). Data are expressed as mean ± SEM; * p < 0.05, ** p < 0.01, *** p < 0.001. NS, not significant.

Background: CXCR1/IL-8RA

The human C-X-C chemokine IL-8 is a potent neutrophil chemotactic and activating factor. Two distinct G protein-linked cell surface receptors, known as IL-8 RA (type I or CXCR1) and IL-8 RB (type II or CXCR2), can interact with the IL-8 molecule. These two receptors share 77% amino acid homology. CXCR1 expression has been documented on neutrophils, monocytes, and a small population of T cells.
