Anti-CXCR4 Antibody, clone 12G5

半岛bd体育手机客户端 说明

一般描述

C-X-C chemokine receptor type 4 (UniProt P61073; also known as CD184, CXC-R4, CXCR-4, FB22, Fusin, HM89, LAP-3, LCR1, LESTR, Leukocyte-derived seven transmembrane domain receptor, Lipopolysaccharide-associated protein 3, LPS-associated protein 3, Neuropeptide Y receptor Y3, NPYRL, SDF-1 receptor, Stromal cell-derived factor 1 receptor) is encoded by the CXCR4 (also known as D2S201E, HSY3RR, LAP3, NPY3R, NPYR, NPYY3R, WHIM, WHIMS) gene (Gene ID 7592) in human. Chemokines and their receptors direct migration of distinct leukocyte subsets to sites of inflammation and to their specific niches in lymphoid organs. Virtually all T cell chemoattractants selectively attract memory/activated T cells. CXCR4 is the seven-transmembrane receptor for SDF-1 that is essential for the development of non-hematopoietic tissues, including heart and B lymphocytes. CXCR4 and CCR5 are two chemokine receptors that also function as co-receptors for human immunodeficiency virus (HIV) entry into CD4+ cells. During the early stages of HIV infection, viral isolates tend to use CCR5 for viral entry, while later isolates tend to use CXCR4.

Research Sub Category
Immunoglobulins & Immunology
Flow Cytometry Analysis: A representative lot detected surface expression of human CXCR4 in various cell types by flow cytometry (Bleul, C.C., et al. (1997). Proc. Natl. Acad. Sci. U S A.94(5):1925-1930; McKnight, A., et al. (1997). J. Virol. 71(2):1692-1696; Endres, M.J., et al. (1996). Cell. 87(4):745-756)
Immunocytochemistry Analysis: A representative lot stained paraformaldehyde-fixed CHO cells transfected to stably express human CXCR4/fusin (Endres, M.J., et al. (1996). Cell. 87(4):745-756).
Neutralizing Analysis: A representative lot blocked SDF-1-induced lymphocyte chemotaxis using freshly isolated human PBMCs (Bleul, C.C., et al. (1997). Proc. Natl. Acad. Sci. U S A.94(5):1925-1930).
Neutralizing Analysis: A representative lot blocked the infection of CXCR4+/CD4+ rhabdomyosarcoma (RD) cells by seven HIV-1 (LAI, RF, Gun-1wt, Gun-1var) and HIV-2 (ROD A/B and CBL-23) strains as assessed by >95% reduced syncytium (multinucleated cell) formation due to viral infection-induced cell-to-cell fusion. Clone 12G5 also blocked Gun-1wt, Gun-1var, and CBL-23, but not the other 4 HIV strains from infecting HeLa/CD4 and C8166 cultures (McKnight, A., et al. (1997). J. Virol. 71(2):1692-1696).
Neutralizing Analysis: A representative lot blocked HIV-2 /vcp strain from infecting U87 cells transfected to express human CXCR4/fusin as assessed a reduction of syncytium (multinucleated cell) formation due to viral infection-induced cell-to-cell fusion (Endres, M.J., et al. (1996). Cell. 87(4):745-756).
Note: Although clone 12G5 binds cell surface CXCR4, efforts to immunoprecipitate or immunoblot CXCR4 were reported to be unsuccessful (Endres, M.J., et al. (1996). Cell. 87(4):745-756).
