Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to
worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting
immunostaining in relation to complex human pathologies.
TCR Screening Services
Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding.
Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Specificity and Use
SIRPA / CD172a antibody was raised against rat peritoneal macrophages.
Recognizes rat CD172a, also known as Signal regulatory protein (SIRP). CD172a is expressed selectively by myeloid cells and by neurons. 3H1939 binds to a different epitope on SIRP than ED9. It does not block the interaction of CD172a-CD47.
Flow Cytometry: 1:10-1:50. Immunohistochemistry: Frozen, Paraffin. Western Blot. The applications listed have been tested for the unmodified form of this product. Other forms have not been tested.
Purified IgG - liquid
Long term: -20°C; Short term: +4°C. Avoid repeat freeze-thaw cycles.
CD172A / SIRPA is a member of the signal-regulatory-protein (SIRP) family, and also belongs to the immunoglobulin superfamily. SIRP family members are receptor-type transmembrane glycoproteins known to be involved in the negative regulation of receptor tyrosine kinase-coupled signaling processes. This protein can be phosphorylated by tyrosine kinases.
