Rantes ELISA Kit (CCL5)

INTENDED USE

Human Rantes ELISA kit is intended for measuring in vitro quantitative levels of regulated on activation normal T cell expressed and secreted (rantes)(CCL5) in human biological fluids, serum, tissue homogenates and plasma (citrate, EDTA, heparin). This assay has a minimum detection limit of 18.75 pg/ml.

BACKGROUND

Rantes is also known as Chemokine (C-C motif) ligand 5 (CCL5), is essentially a natural ligand for the chemokine receptor CCR5 and has the ability to potently suppress the in vitro replication of R5 strains of HIV-1, that is using CCR5 as a co-receptor. It is chemotactic for basophils, eosinophils and T cells, it also plays a vital role in the recruitment of into inflammatory sites. The gene product is predicted to be 10 kDa and after cleavage of the signal peptide, approx. 8 kDa. From the 68 residues remaining, where 4 are cysteines and none are N-linked glycosylated.

Rantes is usually expressed by cultured T cell lines that are growth factor dependent and antigen specific. There is evidence that it can induce the activation and proliferation of a number of natural-killer cells to form CHAK Chemokine-activated killer) cells with the aid of particular cytokines (in particular IL-2 and IFN-γ). CCL5 is also known as a HIV-suppressive factor that can be released from CD8+ T cells. Peripheral blood mononuclear cells or CD4(+) lymphocytes that are obtained from different individuals have been found to display a wide variations in their ability to secrete rantes.
