Background Information
SIRP Alpha, also known as CD172a, SHPS-1, and BIT, belongs to the SIRP family. SIRP Alpha is a transmembrane glycoprotein expressed explicitly on myeloid cells and provides a "do not eat me" signal after engaging with integrin-associated protein CD47 on tumor cells (PMID: 36419386). SIRP Alpha shows heterogeneity in molecular weight (~65-120 kDa) in various tissues due to differential glycosylation (PMID: 18051954). This antibody detects a 75-85 kDa band.

FH Rebecca (Verified Customer) (05-27-2024) | Transference at 4ºC and 90V, for 2h. Antibody incubation ON at 4ºC. Multiple bands observed. A bigger dilution of the antibody is probably needed.
