Description_x000D_ General description_x000D_ MIP-1β (macrophage inflammatory protein 1β) is a member of the CC chemokine (cysteine-cysteine) family, and is produced by monocytes and macrophages. This protein exists as a homodimer. It acts as a ligand to the GPCR (G-protein coupled receptor) called CCR5 (CC chemokine receptor 5)._x000D_ Immunogen_x000D_ Immunogen Sequence: GI # 4506845, sequence 27-92_x000D_ Recombinant chemokine C-C motif ligand 4 isoform 1_x000D_ Application_x000D_ Anti-MIP-1β antibody produced in chicken is suitable for indirect ELISA and western blotting analysis at a dilution of 1:500, for tissue or cell staining at a dilution of 1:200._x000D_ Physical form_x000D_ Solution in phosphate buffered saline containing 0.02% sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ Chemokine (C-C motif) ligand 4 (CCL4) is a principal regulator of macrophage migration and signals through CCR5. CCR5 is linked to several protein kinases including the src kinase Lyn, PI3K, focal adhesion related kinase Pyk2 and members of the MAPK family that help in regulating macrophage chemotaxis. CCL4 is released at the site of inflammation in sarcoidosis.
