Anti-Mouse CCL9 (C1422-GRP)

MIP-1 gamma is a CC chemokine found in mouse blood and a wide variety of mouse tissues, with no known human homolog. MIP-1 gamma signals through the CCR1 receptor. MIP-1 gamma chemoattracts neutrophils and also inhibits colony formation of bone marrow myeloid immature progenitors. MIP-1 gamma contains six cysteines including the four highly conserved cysteine residues present in CC chemokines. Recombinant mouse MIP-1 gamma is an 11.6 kDa protein containing 101 amino acid residues. NC6 chemokines are usually only marginally active at full length, but are converted to highly active forms upon N-terminal truncation. Mature CCL9, in the presence of inflammatory fluids, is naturally truncated by 28, 29 or 30 aa at the N-terminus, generating a highly active, 8 kDa, 71 - 73 aa CCR1 ligand. In contrast, other CCR1 ligands, CCL3/MIP-1α and CCL5/RANTES, lose their potency when proteolytically processed. CCL9/10 is constitutively secreted, and circulates as a full-length molecule. Any onset of inflammation with subsequent enzyme release may act on local NC6 chemokines, generating early, potent leukocyte chemoattractants.
