Recombinant Human MIP-3/CCL23

Stable at 2-8C, but best kept desiccated -20C. Upon reconstitution, stable for up to 1 week at 2-8C. For longer term, store in working aliquots below -20C. Avoid repeated freeze/thaw cycles.

MIP-3/CCL23 is a CC chemokine that signals through the CCR1 receptor. MIP-3 chemoattracts monocytes, resting T-lymphocytes and neutrophils, but does not chemoattract activated lymphocytes. Additionally, MIP-3 has been shown to inhibit colony formation of bone marrow myeloid immature progenitors. Alternative splicing of the MPIF1 gene results in two mRNAs that encode a short (CKbeta8) and a long (CKbeta81) isoform of the chemokine. CKbeta8 cDNA encodes a 120 amino acid (aa) residue precursor protein with a putative 21 aa residue signal peptide that is cleaved to generate a 99 aa residue mature CKbeta8 (aa 22 120). Additional N terminal processing of the 99 aa residue variant can generate a 75 aa residue CKbeta8 (aa 46 120) that is significantly more active than the 99 aa residue variant.

Centrifuge vial prior to opening. Add sterile distilled water or aqueous buffer to a concentration of 0.1-1.0 mg/mL. Further dilutions should be made in appropriate buffered solutions.
