CD47 Rat anti-Mouse, Brilliant Violet 650, Clone: miap301, BD Optibuild™

The miap301 monoclonal antibody specifically binds to the extracellular domain of CD47, also known as Integrin-Associated Protein (IAP). CD47 is a 50-kDa plasma membrane protein with an extracellular immunoglobulin variable region-like domain, a multiple membrane-spanning segment, and a short C-terminal cytoplasmic tail. IAP is often physically associated with β 3 integrins, and it may act as a transducer element in activation mediated by these integrins. CD47 is expressed by a wide variety of cell types, including some cells lacking integrins, such as erythrocytes. The cytoplasmic tail region is expressed as alternatively spliced forms, which are differentially expressed in diverse tissues, suggesting that IAP may have distinct functions in various tissues. CD47 and its ligand, CD172a, are proposed to mediate bi-directional signaling to modify neural synaptic activity and regulate the phagocytic activities of macrophages.

The antibody was conjugated to BD Horizon™ BV650 which is part of the BD Horizon Brilliant™ Violet family of dyes. This dye is a tandem fluorochrome of BD Horizon BV421 with an Ex Max of 405-nm and an acceptor dye with an Em Max at 650-nm. BD Horizon BV650 can be excited by the violet laser and detected in a filter used to detect APC-like dyes (eg, 660/20-nm filter). Due to the excitation and emission characteristics of the acceptor dye, there will be spillover into the APC and Alexa Fluor™ 700 detectors. However, the spillover can be corrected through compensation as with any other dye combination.
