  • Molecular Characterization

    LAG-3 Structure

    Other Tags and Version Biotin & Other Labeled Version

    This protein carries a polyhistidine tag at the C-terminus, and has a calculated MW of 47.1 kDa. The predicted N-terminus is Leu 23. The reducing (R) protein migrates as 55-60 kDa when calibrated against Star Ribbon Pre-stained Protein Marker in SDS-PAGE due to glycosylation.

  • Endotoxin

    Less than 1.0 EU per μg by the LAL method / rFC method.

  • Purity

    >95% as determined by SDS-PAGE.

    >95% as determined by SEC-MALS.

  • Formulation

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

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.
