Recombinant Mouse CCL20/MIP-3 alpha Protein (Catalog # 760-M3)
Measured by its ability to neutralize CCL20/MIP‑3 alpha -induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CCR6. The Neutralization Dose (ND50) is typically 3-15 µg/mL in the presence of 20 ng/mL Recombinant Mouse CCL20/MIP‑3 alpha.
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 CCL20/MIP‑3 alpha and Neutralization by Mouse CCL20/MIP‑3 alpha Antibody. Recombinant Mouse CCL20/MIP‑3 alpha (Catalog # 760-M3) chemoattracts the BaF3 mouse pro‑B cell line transfected with human CCR6 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 Mouse CCL20/MIP‑3 alpha (20 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse CCL20/MIP‑3 alpha Monoclonal Antibody (Catalog # MAB7601). The ND50 is typically 3-15 µg/mL.

Background: CCL20/MIP-3 alpha
MIP-3 alpha, also known as LARC (Liver and Activation-regulated Chemokine) and as Exodus, is one of many novel beta chemokines identified through bioinformatics. Mouse MIP-3 alpha cDNA encodes a 97 amino acid residue precursor protein with a 27 aa residue putative signal peptide that is predicted to be cleaved to form the 70 amino acid (aa) residue mature secreted protein. MIP-3 alpha is distantly related to other beta chemokines (20-28% aa sequence identity). Mouse MIP-3 alpha shares approximately 71% and 63% amino acid sequence homology with rat and human MIP-3 alpha, respectively.
MIP-3 alpha has been shown to be expressed predominantly in lymph nodes, appendix, PBL, fetal liver, fetal lung, and epithelial cells of intestinal tissues. The expression of MIP-3 alpha is strongly up-regulated by inflammatory signals and down-regulated by the anti-inflammatory cytokine IL-10. Synthetic or recombinant MIP-3 alpha has been shown to be chemotactic for lymphocytes and dendritic cells, and inhibits proliferation of myeloid progenitors in colony formation assays. MIP-3 alpha has now been shown to be a unique functional ligand for CCR-6 (previously referred to as GPR-CY4, CKR-L3, or STRL22 orphan receptor), a chemokine receptor that is selectively and highly expressed in human dendritic cells derived from CD34+ cord blood precursors.
