  • Synonym
    CD33,SIGLEC3,gp67
  • Source
    FITC-Labeled Human Siglec-3, His Tag (CD3-HF224) is expressed from human 293 cells (HEK293). It contains AA Asp 18 - His 259 (Accession # AAH28152.1). It is the FITC labeled form of Human Siglec-3, His Tag (CD3-H5226).
    Predicted N-terminus: Asp 18
  • Molecular Characterization
    Siglec-3 Structure

    This protein carries a polyhistidine tag at the C-terminus

    The protein has a calculated MW of 27.6 kDa. The protein migrates as 40-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Conjugate

    FITC

    Excitation source: 488 nm spectral line, argon-ion laser

    Excitation Wavelength: 488 nm

    Emission Wavelength: 535 nm

  • Labeling
    The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with FITC using standard chemical labeling method. The residual FITC is removed by molecular sieve treatment during purification process.
  • Protein Ratio
    The FITC to protein molar ratio is 1.5-3.5.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

2e5 of anti-Siglec-3 CAR-293 cells were stained with 100 μL of 1 μg/mL of FITC-Labeled Human Siglec-3, His Tag (Cat. No.CD3-HF224) and negative control protein respectively, FITC signal was used to evaluate the binding activity (QC tested).

  • Background
    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.
