  • 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: Glu 30
  • 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.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • 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.

  • 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.
