The MR106 monoclonal antibody specifically recognizes CD106, the ~110 kDa transmembrane vascular cell adhesion molecule-1 (VCAM-1). Expression of CD106 on endothelial cells is induced by inflammatory cytokines and in certain pathologic conditions. In the rat bone marrow, CD106 is reportedly expressed on dendritic cells and subsets of the myeloid lineage, but not detectable on peripheral leucocytes. CD106 can reportedly serve as a counter-receptor for VLA-4 (α4β1 integrin) and α4β7 integrin, and it plays an important role in leucocyte extravasation, particularly at sites of inflammation.
The antibody was conjugated to BD Horizon BUV395 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. With an Ex Max near 348 nm and an Em Max near 395 nm, BD Horizon BUV395 can be excited by the ultraviolet laser (355 nm) laser and detected with a 379/28 filter. This dye has been exclusively developed by BD Biosciences as an optimal dye for use on instruments equipped with the ultraviolet laser and has virtually no spillover into any other detector.
