Human HLA-A*02:01&B2M&PRAME (SLLQHLIGL) Tetramer Protein (MALS verified)

Human HLA-A*02:01&B2M&PRAME (SLLQHLIGL) Tetramer Protein (MALS verified)

• Background: This gene encodes an antigen that is preferentially expressed in human melanomas and that is recognized by cytolytic T lymphocytes. It is not expressed in normal tissues, except testis. The encoded protein acts as a repressor of retinoic acid receptor, and likely confers a growth advantage to cancer cells via this function. Alternative splicing results in multiple transcript variants. The PRAME (SLLQHLIGL) was shown to be recognized by HLA-A*0201 tumor-infiltrating lymphocytes from melanoma patients, and therefore it is widely been studied in TCR-T studies. The Human HLA-A*0201 PRAME (SLLQHLIGL) complex protein is a complex of HLA-A*0201 of the MHC Class I, B2M and PRAME (SLLQHLIGL) peptide.
• Description: Human HLA-A*02:01&B2M&PRAME (SLLQHLIGL) Tetramer Protein (HLE-H52H9) is expressed from human 293 cells (HEK293). It contains AA Ile 21 - Met 119 (B2M) & Gly 25 - Ile 308 (HLA-A*02:01) & SLLQHLIGL peptide (Accession # P61769 (B2M) & AAA59606.1 (HLA-A*02:01) & SLLQHLIGL).
• Specifications: Human HLA-A*02:01&B2M&PRAME (SLLQHLIGL) Tetramer Protein is assembled by biotinylated monomer (HLE-H82E8) and streptavidin. Biotinylated Human HLA-A*02:01&B2M&PRAME (SLLQHLIGL) Complex Protein is produced by co-expression of HLA and B2M loaded with PRAME peptide. Biotinylated Human HLA-A*02:01&B2M&PRAME (SLLQHLIGL) Complex Protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™). The protein has a calculated MW of 51.3 kDa and 13.8 kDa. The protein migrates as 55-60 kDa and 12 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
