Biotinylated Mouse LAG-3 / CD223 Protein, His,Avitag™ (MALS verified)

  • Synonym
    LAG3,CD223,FDC
  • Source
    Biotinylated Mouse LAG-3, His,Avitag (LA3-M82E5) is expressed from human 293 cells (HEK293). It contains AA Gly 24 - Leu 442 (Accession # Q61790-1).
    Predicted N-terminus: Gly 24
  • Molecular Characterization
    Online(Gly 24 - Leu 442) Q61790-1

    This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

    The protein has a calculated MW of 48.8 kDa. The protein migrates as 55-65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Biotinylation
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Biotin:Protein Ratio
    The biotin to protein ratio is 0.5-1 as determined by the HABA assay.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

The purity of Biotinylated Mouse LAG-3, His,Avitag (Cat. No. LA3-M82E5) was more than 90% and the molecular weight of this protein is around 112-136kDa verified by SEC-MALS.

  • Background
    Lymphocyte activation gene 3 protein (LAG3) is also known as CD antigen CD223 and protein FDC, which belongs to immunoglobulin (Ig) superfamily and contains 4 extracellular Ig-like domains. The LAG3 gene contains 8 exons. The sequence data, exon/intron organization, and chromosomal localization all indicate a close relationship of LAG3 to CD4. LAG3 /CD223 involved in lymphocyte activation. LAG3 /CD223 binds to HLA class-II antigens.
