Human SIRP gamma, Fc Tag (SIG-H5253) is expressed from human 293 cells (HEK293). It contains AA Glu 29 - Ser 364 (Accession # AAH64532).
Predicted N-terminus: Glu 29
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 63.7 kDa. The protein migrates as 67-85 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.

Immobilized Human CD47, His Tag (Cat. No. CD7-H5227) at 5 μg/mL (100 μL/well) can bind Human SIRP gamma, Fc Tag (Cat. No. SIG-H5253) with a linear range of 20-312 ng/mL (QC tested).
Signal-regulatory protein gamma (SIRPG or SIRP-gamma) is also known as CD172 antigen-like family member B (CD172g), Signal-regulatory protein beta-2 (SIRPB2), is a single-pass type I membrane protein. SIRPG is expressed on CD4+ T-cells, CD8+ T-cells, CD56-bright natural killer (NK) cells, CD20+ cells, and all activated NK cells. SIRPG interacts with CD47. On binding with CD47, CD172g mediates cell-cell adhesion.
