Recombinant Cotton Rat CCL5/RANTES (Catalog # 1010-CR)
Measured by its ability to neutralize CCL5/RANTES-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with mouse CCR5. The Neutralization Dose (ND50) is typically 1-4 µg/mL in the presence of 0.2 µg/mL Recombinant Cotton Rat CCL5/RANTES.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Chemotaxis Induced by CCL5/RANTES and Neutralization by Cotton Rat CCL5/RANTES Antibody. Recombinant Cotton Rat CCL5/RANTES (Catalog # 1010-CR) chemoattracts the BaF3 mouse pro‑B cell line transfected with mouse CCR5 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Cotton Rat CCL5/RANTES (0.2 µg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Cotton Rat CCL5/RANTES Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1010). The ND50 is typically 1-4 µg/mL.

CCL5, also known as RANTES (Regulated upon Activation, Normal T cell Expressed and presumably Secreted), is an 8 kDa beta ‑chemokine that plays a primary role in the inflammatory immune response by means of its ability to attract and activate leukocytes (1‑3). Human and mouse RANTES exhibit cross-species activity on human and mouse cells (4). Mature cotton rat CCL5 shares 88% aa seqeuence identity with mouse and rat CCL5 and 71%‑77% with canine, feline, and human CCL5. CCL5 is secreted by many cell types at inflammatory sites, and it exerts a wide range of activities through the receptors CCR1, CCR3, CCR4, and CCR5 (5, 6). Inflammatory responses can be impaired by the sequestration of CCL5 by the cytomegalovirus protein US28 (7). In humans, CCR5 binding to CCL5 inhibits the infectivity of R5 (M-tropic) but not X4 (T-tropic) strains of HIV-1 (8). The two N-terminal residues of CCL5 can be removed by CD26/DPPIV, generating a protein that functions as a chemotaxis inhibitor and more effectively blocks M-tropic HIV-1 infection of monocytes (9). Oligomerization of CCL5 on glycosaminoglycans is required for CCR1-mediated leukocyte adhesion and activation as well as CCL5’s interaction with the chemokine CXCL4/PF4 (10‑12). The deposition of CCL5 on activated vascular endothelial cells is crucial for monocyte adhesion to damaged vasculature, but CCL5 oligomerization is not required for the extravasation of adherent leukocytes (13‑15). CCL5 is upregulated in breast cancer and promotes tumor progression through the attraction of proinflammatory macrophages in addition to its actions on tumor cells, stromal cells, and the vasculature (16).
