ChemiScreen CXCR2 Membrane Preparation

Descrição detalhada : TRANSFECTION: Full-length human CXCR2 cDNA (Accession Number: M73969), CXCR2 is a 7-TM G-protein coupled receptor that binds to the chemokines GROalpha, GRObeta, GROgamma, IL-8, ENA-78, NAP-2 and GCP-2 (Olson and Ley, 2002). Neutrophils, mast cells and microvascular endothelial cells express CXCR2, and interactions of CXCR2 with its ligands promotes chemotaxis of these cell types (Heidemann et al., 2003; Nilsson et al., 1999; White et al., 1998). Studies with mice lacking CXCR2 indicate that CXCR2 promotes growth of primary tumors and secondary metastases (Keane et al., 2004), and plays an essential role in hyperoxia-induced lung injury (Sue et al., 2004). In addition, cytomegalovirus encodes a CXCR2-binding chemokine, vCXC-1, that promotes neutrophil migration to infected cells (Penfold et al., 1999). Chemicon's CXCR2 Membrane Preps are ideal tools for screening for antagonists of interactions between CXCR2 and its ligands. Radiolabeled IL-8 binds to the CXCR2 membranes with a Kd of 0.075 nM. With 0.1 nM 125I-labeled IL-8, a 5-fold window of specific binding is obtained.
