Human Siglec-7 / CD328 Protein, His Tag (MALS verified)

  • Synonym
    CDw328,D-siglec,A79 membrane protein,p75,Adhesion inhibitory receptor molecule 1, AIRM-1
  • Source
    Human Sigelc-7, His Tag (SG7-H5225) is expressed from human 293 cells (HEK293). It contains AA Gln 19 - Leu 353 (Accession # Q9Y286-1).
    Predicted N-terminus: Gln 19
  • Molecular Characterization
    Online(Gln 19 - Leu 353) Q9Y286-1

    This protein carries a polyhistidine tag at the C-terminus.

    The protein has a calculated MW of 38.8 kDa. The protein migrates as 55-65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

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

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 25 mM MES, 150 mM NaCl, pH5.5. Normally trehalose is added as protectant before lyophilization.

Immobilized Human Sigelc-7, His Tag (Cat. No. SG7-H5225) at 5 μg/mL (100 μL/well) can bind Neu5Aca2-6GalNAca-PAA-biotin with a linear range of 6-100 ng/mL (QC tested).

  • Background
    Siglec-7 is a member of the human CD33‐related Siglec receptor. The extracellular region of Siglec‐7 is characterized by an N‐terminal V‐set Ig domain that can bind sialic acid and two C2‐set Ig domains. The cytoplasmic tail of Siglec‐7 has one immune‐receptor tyrosine‐based inhibitory motif (ITIM) and one ITIM‐like motif. Siglec-7 is considered as a sialic acid-dependent immunoreceptor with inhibitory potential and expressed predominantly on human NK cells, monocytes and a small subset of CD8+ T cells.
