Recombinant Rat CXCL2/GRO beta /MIP‑2/CINC‑3 (Catalog # 525-C3)
Measured by its ability to neutralize CXCL2/GRO beta /MIP‑2/CINC‑3-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CXCR2. The Neutralization Dose (ND50) is typically 0.5-2.5 µg/mL in the presence of 0.1 µg/mL Recombinant Rat CXCL2/GRO beta /MIP‑2/CINC‑3.
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.
Chemotaxis Induced by CXCL2/CINC‑3 and Neutralization by Rat CXCL2/CINC‑3 Antibody. Recombinant Rat CXCL2/CINC‑3 (Catalog # 525‑C3) chemoattracts the BaF3 mouse pro‑B cell line transfected with human CXCR2 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 Rat CXCL2/CINC‑3 (0.1 µg/mL) is neutralized (green line) by increasing concentrations of Rat CXCL2/CINC‑3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF525). The ND50 is typically 0.5-2.5 µg/mL.

Background: CXCL2/GRO beta/MIP-2/CINC-3
Cytokine-induced neutrophil chemoattractant 3 (CINC-3) has been found to be expressed by cytokine-stimulated rat alveolar macrophages and fibroblasts. Based on its protein and DNA sequences, CINC-3 (also known as rat MIP-2, GRO beta and CXCL2) is a member of the alpha (CXC) subfamily of chemokines.
CINC-3 cDNA encodes a 100 amino acid (aa) residue precursor protein with a 31 aa signal peptide that is cleaved to yield a 69 aa mature secreted protein. The protein sequence of rat CINC-3 shares approximately 88% identity with murine MIP-2. Characteristic of ELR containing CXC chemokines, CINC-3 is known to be a potent chemotactic factor for rat neutrophils in vitro and in vivo. On the basis of cross-desensitization results of the various CINC proteins, it has been postulated that rat neutrophils have at least two classes of CINC receptors: a class of CINC-3 specific receptors as well as a second common receptor shared by all CINCs.
