The Z8-50.23 monoclonal antibody specifically recognizes the mouse CX3C chemokine receptor 1 (CX3CR1), which is also known as Fractalkine receptor, G protein-coupled receptor 13 (GPR13), or GPRV28 (V28). CX3CR1 is an ~40 kDa, seven-transmembrane G protein-coupled receptor that is expressed on monocytes, activated macrophages, NK cells, a subset of memory T cells, dendritic cells (DC), and mast cells. CX3CR1 is a receptor for the CX3C chemokine, CX3CL1, which is also known as fractalkine or neurotactin. CX3CL1 is expressed on activated endothelial cells, neurons, and astrocytes. CX3CR1 plays a role in leucocyte adhesion and extravasation from blood vessels during inflammation.
The antibody was conjugated to BD Horizon™ BV480 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 436-nm and Em Max at 478-nm, BD Horizon™ BV480 can be excited by the violet laser and detected in the BD Horizon™ BV510 (525/40-nm) filter set. BV480 has less spillover into the BV605 detector and, in general, is brighter than BV510.
