Human LAG-3 / CD223 Protein, His Tag (MALS verified)

Human LAG-3 / CD223 Protein, His Tag (MALS verified)

• 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.
• Description: Human LAG-3 / CD223 Protein, His Tag (LA3-H52H3) is expressed from human 293 cells (HEK293). It contains AA Leu 23 - Leu 450 (Accession # P18627-1).
• Specifications: This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 48.1 kDa. The protein migrates as 58-65 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
