Protein Construction:A DNA sequence encoding the human SIRPG (NP_061026.2) extracellular domain (Met 1-Ser 364) was expressed, with a polyhistidine tag at the C-terminus.
Expressed Host:Human Cells
Shipping:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Human SIRPG Protein QC Testing
Purity:> 96 % as determined by SDS-PAGE
Bio-Activity:Measured by its binding ability in a functional ELISA.
Immobilized human SIRPG-His at 10 μg/ml (100 μl/well) can bind human CD47-Fc (Cat:12283-H02H), The EC50 of human CD47-Fc (Cat:12283-H02H) is 0.58-1.34 μg/ml.

SIRPG/SIRP gamma/CD172g Background

Signal-regulatory protein gamma (SIRPG/SIRP gamma) also known as CD172 antigen-like family member B, CD172g, and CD172g antigen, 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. SIRPG/SIRP gamma/CD172g is probable immunoglobulin-like cell surface receptor. On binding with CD47, SIRPG can mediate cell-cell adhesion. SIRPG/SIRP gamma is engagement on T-cells by CD47 on antigen-presenting cells results in enhanced antigen-specific T-cell proliferation and costimulates T-cell activation. SIRPG/SIRP gamma/CD172g is detected in liver, and at very low levels in brain, heart, lung, pancreas, kidney, placenta and skeletal muscle. Expressed on CD4+ T-cells, CD8+ T-cells, CD56-bright natural killer (NK) cells, CD20+ cells, and all activated NK cells. This cytokine is mainly present in the paracortical T-cell area of lymph nodes, with only sparse positive cells in the mantle and in the germinal center of B-cell follicles. In the thymus, SIRPG is primarily expressed in the medulla on mature T-lymphocytes that have undergone thymic selection.
