产品描述 概述Chemokine (C-C motif) ligand 5 (CCL5) also known as RANTES is classified as a chemotactic cytokine or chemokine. It is encoded by the CCL5 gene in humans. CCL5 is chemotactic for T cells, eosinophils, and basophils, and plays an active role in recruiting leukocytes into inflammatory sites which has been reported to be produced by renal tubular epithelium, synovial fibroblasts and selected tumor cells. It also induces the proliferation and activation of certain natural-killer cells to form CHAK cells. Recombinant human CCL5 contains 68 amino acids and it shares 84 % a.a. sequence identity with murine and rat CCL5, respectively. 使用说明This material is offered by Novin Biotech for research, laboratory or further evaluation purposes.
