Applications

Recommended Concentration

Sample

Flow Cytometry

0.25 µg/10⁶ cells

Immunohistochemistry

0.5-25 µg/mL

See below

CyTOF-reported

Cheng, Y. et al. (2016) J. Immunol. 196: 924. Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Neutralization

Measured by its ability to neutralize CXCL8/IL‑8-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CXCR1. The Neutralization Dose (ND₅₀) is typically 0.4-2.0 µg/mL in the presence of 1 ng/mL Recombinant Human CXCL8/IL‑8.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Detection of CXCR1/IL‑8 RA in Human Blood Granulocytes by Flow Cytometry. Human peripheral blood granulocytes were stained with Mouse Anti-HumanCXCR1/IL-8 RA Monoclonal Antibody (Catalog # MAB330R, filled histogram) or isotype control antibody (Catalog # MAB003, open histogram), followed by PE-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0102B).

Neutralization

View Larger

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 # MAB330R). The ND₅₀ is typically 0.4-2.0 µg/mL.

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.
