CX3CR1, NT (Beta Chemokine Receptor-like 1, CCRL1, Chemokine C-X3-C Motif Receptor 1, CX3C Chemokine Receptor 1, C-X3-C CKR-1, CX3C CKR-1, CMK-BRL-1, CMKBLR1, CMKDR1, Fractalkine Receptor, GPR13, GPRV28, V28)

CX3CR1 is one of the chemokine receptors that is required as a coreceptor for HIV infection. The genes encoding human, murine, and rat CX3CR1 were cloned and designated V28 and CMKBRL1, CX3CR1, and RBS11, respectively (1-4). The encoded seven transmembrane proteins were recently identified as the receptors for a novel transmembrane molecule, fractalkine, and renamed CX3CR1 (5). Recently, CX3CR1 was found to serve as a coreceptor for HIV-1 and HIV-2 envelope fusion and virus infection, which can be inhibited by fractokine (6). CX3CR1 mediates leukocyte migration and adhesion (5). CX3CR1 is expressed in a variety of human tissues and cell lines (2). \n\nApplications: \nSuitable for use in Immunohistochemistry and Western Blot. Other applications not tested.\n\nRecommended Dilutions:\nImmunohistochemistry: 2ug/ml\nWestern Blot: 1:500-1:2000\nOptimal dilutions to be determined by the researcher.\n\nControl Peptide: \nC8300P\n\nPositive Control: \nHuman spleen tissue lysate\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile 40-50% glycerol, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
