Product Specifications

Product Specific Information

• Immunohistochemistry (PFA fixed):
  Incubate antibody for 30 min at room temperature.
  Staining of formalin-fixed tissues requires heating tissue sections in 10 mM Tris with 1 mM EDTA, pH 9.0, for 45 min at 95°C, followed by cooling at room temperature for 20 min.

• Western Blot:
  Use 1–2 µg/mL for 60 minutes at room temperature.

Target Information

CD47 (integrin-associated protein, IAP) is a ubiquitously expressed cell surface transmembrane glycoprotein that interacts with several integrins to regulate their functions. Engagement of CD47 by soluble ligands or counter receptors modulates various signaling pathways, including activation of heterotrimeric G proteins. Functionally, CD47 is involved in increasing intracellular calcium concentration during cell adhesion to the extracellular matrix. It also serves as a receptor for the C-terminal cell binding domain of thrombospondin and may play roles in membrane transport and signal transduction.

CD47 has broad tissue distribution but reduced expression on Rh erythrocytes. It acts as a ligand for CD172a (signal regulatory protein alpha, SIRPα), an immune inhibitory receptor on macrophages, preventing phagocytosis of CD47-positive cells. The CD47–CD172a system influences cell migration, B cell adhesion, T cell activation, chondrocyte mechanotransduction, and neuronal development, being especially abundant in synapse-rich regions of the brain and retina.
