• Species Reactivity

  Human

• Specificity

  Detects human CXCR2/IL-8 RB transfected NS0 cells but not the parental cell line. It does not cross-react with CXCR1 (IL-8 RA).

  Met1-Leu355    
  Accession # AAB25880

• Formulation

  Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.

• Endotoxin Level

  <0.10 EU per 1 μg of the antibody by the LAL method.

• CyTOF-ready

  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 CXCL1/GRO alpha /KC/CINC‑1-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CXCR2. The Neutralization Dose (ND    ₅₀) is typically 1-5 µg/mL in the presence of 5 ng/mL Recombinant Human CXCL1/GRO alpha /KC/CINC‑1.

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

Background: CXCR2/IL-8 RB

CXCR2, also known as IL-8 RB, is a G protein-coupled chemokine receptor expressed on neutrophils. It binds IL-8, GRO alpha, GRO beta, GRO gamma, NAP-2, and ENA-78.
