InVivoMAb anti-mouse CD172a (SIRPα)
The P84 monoclonal antibody reacts with Signal-Regulatory Protein α (SIRPα), also known as CD172a. SIRPα is a type I transmembrane glycoprotein expressed on monocytes, macrophages, and dendritic cells. Neurons and other tissues of the central nervous system have also been shown to express SIRPα. Its ligand, CD47 is expressed by a wide variety of cells. SIRPα and CD47 regulate dendritic cell-mediated T cell activation, neutrophil migration, and phagocytosis. SIRPα diffuses laterally on the macrophage membrane and accumulates at a phagocytic synapse to bind CD47 which inhibits phagocytosis by macrophages. Anti-SIRPα antibodies that block the interaction of SIRPα with CD47 have been shown to suppress tumor formation in mice. The P84 antibody has been shown to have neutralizing activity in vivo and in vitro.
This Antibody Is Useful For:
- In vivo SIRPα blocking
- In vitro SIRPα blocking
- Western blot
- Flow cytometry
As always Bio X Cell antibodies are specifically formulated for in vivo use and feature:
- 95% purity
- Ultra-low endotoxin levels
- Preservative, stabilizer, and carrier protein-free
