Validation:

KD Validation (Figure 2) : Anti-CX3CR1 antibody (2093) specificity was further verified by CX3CR1 specific knockdown. CX3CR1 signal in 293 cells transfected with CX3CR1 siRNAs was disrupted in comparison with that in cells transfected with control siRNAs.

Regulated expression validation (Figure 13) : CX3CR1 expression detected by anit-CX3CR1 antibodies (2093) was up-regulated by IL-2, which was inhibited by IL-15.

Deficiency Validation (Figure 15) : CX3CR1+ cells detected by anti-CX3CR1 antibodies is localized in vascular wall of CX3CR1^+/gfp mice, but not in CX3CR1^gfp/gfp mice, where cells remained in perivascular region.

Isoform: Human CX3CR1 has 3 isoforms, including isoform 1 (355aa, 40kD) , isoform 2 (387aa, 44kD) , isoform 3 (362aa, 41kD) . Mouse CX3CR1 has one isoform (354aa, 40kD) and rat CX3CR1 also has one isoform (354aa, 40kD) . 2093 can detect all isoforms of human, mouse and rat.

BACKGROUND: CX3CR1 Antibody: CX3CR1 is one of the chemokine receptors that are required as coreceptors for HIV infection. The genes encoding human, murine, and rat CX3CR1 were cloned and designated V28 and CMKBRL1, CX3CR1, and RBS11, respectively. The encoded seven transmembrane protein was recently identified as the receptor for a novel transmembrane molecule, fractalkine, and renamed CX3CR1. 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. CX3CR1 mediates leukocyte migration and adhesion. CX3CR1 is expressed in a variety of human tissues and cell lines.
