The BZ2E3 monoclonal antibody specifically binds to CCRL2 (C-C chemokine receptor-like 2) which is also known as Lipopolysaccharide-inducible C-C chemokine receptor (L-CCR/Lccr). CCRL2 is a chemokine receptor-like, 7-transmembrane protein that can bind CCL19 or the nonchemokine chemoattractant, chemerin/RARRES2. CCRL2 is expressed by a variety of cell types including mast cells, macrophages and some endothelial cells. CCRL2 appears to play various roles in regulating chemokine activities, e.g., by binding and internalizing excess local levels of the CCL19/MIP-3β chemokine. Alternatively, endothelial cell-expressed CCRL2 can bind and present the chemerin/RARRES2 chemoattractant to lymphoid cells that express the functional signaling receptor, CMKLR1, and promote their adhesion.
The antibody was conjugated to BD Horizon™ BUV395 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye has been exclusively developed by BD Biosciences to have minimal spillover into other detectors, making it an optimal choice for multicolor flow cytometry. With an Ex Max at 348 nm and an Em Max at 395 nm, BD Horizon BUV395 can be excited with a 355 nm laser and detected with a 379/28 filter.
