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 β3 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™ 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.
