SIRP, alpha1 (SIRPa, Signal Regulatory Protein, SHPS-1, BIT, p84, CD172a)

May be stored at 4 °C for short-term only. For long-term storage, store at -20 °C. Aliquots are stable for at least 12 months at -20 °C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Recognizes rat CD172a, also known as Signal regulatory protein (SIRP). CD172a is expressed selectively by myeloid cells and by neurons. Binds to a different epitope on SIRP than ED9. Does not block the interaction of CD172a-CD47.
