Recombinant Human C-C motif chemokine 5 protein (CCL5) (Active)
Description
Purity > 95% as determined by SDS-PAGE. MW: 45.5kDa. Partial: 31-205aa. C-terminal FC-tagged. Homo sapiens (Human). Interleukin 15 Receptor alpha (IL-15Ra) is a transmembrane glycoprotein that plays a pleiotropic role in immune development and function, including the positive maintenance of lymphocyte homeostasis. IL-15Ra chain can bind soluble IL-15 and ``transpresent'' cytokine to the cells, allowing them to respond to IL-15. Soluble IL-15Ra can function as a specific high-affinity IL-15 antagonist. The soluble IL-15/IL-15Ra complexes exhibit a strong agonistic activity which is mediated through membrane-bound IL-15 receptor β and ? heterodimers and enables signaling to cells.
