Immunofluorescence Validation of CX3CR1 in Human Atherosclerosis (Lucas et al., 2003). CX3CR1-positive cells in coronary artery sections was detected by anti-CX3CR1 antibodies by double staining with an anti–smooth muscle actin antibody (yellow).

Regulated Expression Validation of CX3CR1 in Mouse Bone Marrow-derived NK Cells (Barlic et al., 2003). Western blot analysis of CX3CR1 expression detected by anti-CX3CR1 antibodies was induced by IL-2 but was inhibited by IL-15. Mouse skeletal muscle was for negative control and mouse brain was for positive control.

Flow Cytometry Validation of CX3CR1 in Peripheral Blood Mononuclear Cells (PBMCs) of Patients (Yajima et al., 2005). Flow cytometry analysis of CX3CR1 expression detected by anti-CX3CR1 antibodies. Protein expression was more pronounced on CD4 + and CD8 + T cells from patients with untreated active systemic lupus erythematosus (SLE) as compared to those with rheumatoid arthritis (RA) or healthy controls.

CX3CR1 Deficiency Validation in Transgenic Mice (Kumar et al., 2013). Transgenic CX3CR1 gfp (C57BL6/J background) mice, in which either one (CX3CR1 gfp/+) or both (CX3CR1 gfp/gfp) copies of the CX3CR1 gene were interrupted by fluorescent protein (GFP). More CX3CR1 positive cells (green) are found in vascular wall of CX3CR1 gfp/+ mice, but not in CX3CR1 gfp/gfp mice, where cells remained in perivascular region due to leaky microvessels. CX3CR1 expression was detected by anti-CX3CR1 antibodies.
