RecombinantMIP-1α/CCL3, Mouse

MIP-1 alpha/CCL3, also known as LD78 alpha, is an inflammatory chemokine. MIP-1α belongs to the CCL chemokine family, and shares 68% homology with MIP-1β. The mature form of MIP-1α contains 69 amino acids, exists as dimers in solution, and tends to undergo reversible aggregation. The receptors of MIP-1αin vivo are mainly the G-protein coupled receptors CCR1 and CCR5. Upon stimulation by endogenous and exogenous agents such as Interleukin-1β, Interferon-γ, and lipoteichoic acid from gram-positive bacteria, monocytes are able to secrete significant amounts of MIP-1α. MIP-1α augments the adhesions of T lymphocytes, monocytes, and neutrophils to vascular cell adhesion molecule 1. Additionally, in wounds, MIP-1αchemoattracts macrophages in order to accelerate the tissue repair process.Recombinant Mouse MIP-1 alpha/CCL3 (rmMIP-1α) produced in HEK 293cells is a single polypeptide chain containing 69 amino acids. A fully biologically active molecule, rmMIP-1αhas a molecular mass of 7.8 kDa analyzed by reducing SDS-PAGE and is obtained by chromatographic techniques at GenScript.
