    CD33,SIGLEC3,gp67
  • 출처
    Human Siglec-3 (18-132), Fc Tag (CD3-H5255) is expressed from human 293 cells (HEK293). It contains AA Pro 18 - His 132 (Accession # P20138-3).
    Predicted N-terminus: Pro 18
  • 분자 표징
    Online(Pro 18 - His 132) P20138-3

    This protein carries a human IgG1 Fc tag at the C-terminus.

    The protein has a calculated MW of 38.6 kDa. The protein migrates as 46-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • 내독소
    Less than 1.0 EU per μg by the LAL method.
  • 순도

    >95% as determined by SDS-PAGE.

  • 레시피

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, 150 mM NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

  • 백그라운드
    Myeloid cell surface antigen CD33 is also known as SIGLEC3, Siglecs (sialic acid binding Ig­like lectins) and GP67, is a single-pass type I membrane protein which belongs to the immunoglobulin superfamily and SIGLEC (sialic acid binding Ig-like lectin) family. Human CD33 / Siglec-3 cDNA encodes a 364 amino acid (aa) polypeptide with a hydrophobic signal peptide, an N-­terminal Ig-­like V­-type domain, one Ig­-like C2-­type domains, a transmembrane region and a cytoplasmic tail. CD33 / Siglec-3 usually considered myeloid-specific, but it can also be found on some lymphoid cells. In the immune response, CD33 / Siglec-3 may act as an inhibitory receptor upon ligand induced tyrosine phosphorylation by recruiting cytoplasmic phosphatase(s) via their SH2 domain(s) that block signal transduction through dephosphorylation of signaling molecules. CD33 / Siglec-3 induces apoptosis in acute myeloid leukemia.
