Product Specific Information

For reconstitution, add 100 µL of distilled water to achieve a final antibody concentration of approximately 1 mg/mL.
For conjugation experiments, perform an additional desalting step (e.g., Zeba Spin Desalting Columns, 7K MWCO, 0.5 mL, Product #89882).

Target Information

SIRP alpha (CD172a, signal-regulatory protein alpha) is a receptor-type transmembrane glycoprotein expressed on myeloid cells such as granulocytes, dendritic cells, macrophages, mast cells, and hematopoietic stem cells.
It acts as a substrate for activated tyrosine kinases (EGFR, PDGFR, Src, insulin receptor) and negatively regulates receptor tyrosine kinase-coupled signaling pathways.
Binding of SIRP alpha to CD47 triggers phosphorylation of ITIM motifs, leading to recruitment of SHP-1 and SHP-2 phosphatases.
This interaction regulates processes such as inhibition of macrophage phagocytosis and activation of T cells and dendritic cells.
SIRP alpha influences cellular responses to serum, growth factors, insulin, oncogenes, and adhesion, playing roles in physiological and pathological processes.
Cancer cells often overexpress CD47, activating SIRP alpha and preventing macrophage-mediated destruction of tumor cells.
