Recombinant Human Macrophage Inflammatory Protein-1 beta/CCL4

Product Specifications

Background

CCL4 encoded by the CCL4 gene, also known as Macrophage Inflammatory Protein-1 beta; (MIP-1 beta; ) is a CC chemokine with specificity for CCR5 receptors and it is a major HIV-suppressive factor produced by CD8+ T cells. It is a monokine with inflammatory and chemokinetic properties. Recombinant CCL4 induces a dose-dependent inhibition of different strains of HIV-1, HIV-2, and simian immunodeficiency virus (SIV) . Specifically, MIP-1-beta (3-69) is also a ligand for CCR1 and CCR2 isoform B. Recombinant human CCL4 contains 69 amino acids and it shares 77 % and 80 % a.a. sequence identity with murine and rat CCL4, respectively. Both human and murine MIP-1 alpha; and MIP-1 beta; are active on human and murine hematopoietic cells.
