Description
SIRPA Human Recombinant produced in E.Coli is a single,
non-glycosylated polypeptide chain containing 370 amino acids (27-373 a.a) and
having a molecular mass of 40.4kDa. SIRPA is fused to a 23 amino acid His-tag at N-terminus
& purified by proprietary chromatographic techniques.

Introduction
Signal-Regulatory Protein Alpha, SIRPA belongs to the
signal-regulatory-protein (SIRP) family, as well as the immunoglobulin super family. The members
of the SIRP family are receptor-type
transmembrane glycoproteins which are involved in the negative regulation of receptor tyrosine
kinase-coupled signaling processes. SIRPA can be phosphorylated
by tyrosine kinases. The phospho-tyrosine residues of this PTP have been shown
to recruit SH2 domain
containing tyrosine phosphatases (PTP), and perform as substrates of PTPs. SIRPA take part in signal transduction mediated by a variety
of growth factor receptors. CD47 has been shown to be a ligand for SIRPA.
Physical Appearance
Sterile Filtered colorless solution.
Formulation
SIRPA protein solution (0.5mg/ml) containing PBS buffer
(pH 7.4), 10% glycerol and 1mM DTT.
Stability
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles.
Purity
Greater than 90.0% as determined by SDS-PAGE.
