表达区间及表达系统(Source)

Human SIRP beta, Fc Tag (SIA-H5257) is expressed from human 293 cells (HEK293). It contains AA Glu 30 - Leu 371 (Accession # O00241-1).

Predicted N-terminus: Glu30

蛋白结构(Molecular Characterization)

Online(Glu 30 - Leu 371) O00241-1

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 70-80 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

电泳(SDS-PAGE)

Human SIRP beta, Fc Tag (Cat. No. SIA-H5257) SDS-PAGE gel

Human SIRP beta, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.

背景(Background)

Signal-regulatory protein beta-1 (SIRP beta 1) also known as SIRPβ1, belongs to signal-regulatory-protein (SIRP) family, and immunoglobulin superfamily. SIRPβ1 is a transmembrane protein that has three Ig-like domains in its extracellular region and a short cytoplasmic tail. Human SIRPβ1 is expressed on monocytes and granulocytes but not on lymphocytes. SIRP beta 1 contains short cytoplasmic domains that lack cytoplasmic sequence motifs capable of recruiting SHP-2 and SHP-1. In addition, they contain a single basic lysine residue within the hydrophobic transmembrane domain.
