Biotinylated Human HLA-A*03:01&B2M&gp100 (ALLAVGATK) Complex Protein (Monomer, MALS verified)

Biotinylated Human HLA-A*03:01&B2M&gp100 (ALLAVGATK) Complex Protein (Monomer, MALS verified)

• Background: Glycoprotein 100, is also well known as gp100 and Melanocyte protein PMEL. This antigen is a melanocyte-specific type I transmembrane glycoprotein and composed of 661 amino acids. Glycoprotein 100 is related to the tumor regression in metastatic melanoma patients after adoptive therapy, by which its epitopes being recognized by tumor lymphocytes and T-cells. The gp100280–288(YLEPGPVTA) was originally shown to be recognized by HLA-A*0301 tumor-infiltrating lymphocytes from melanoma patients, and therefore it is widely been studied in TCR -T studies. The Human HLA-A*0301 gp100 (YLEPGPVTA) complex protein is a complex of HLA-A*0301 of the MHC Class I, B2M and YLEPGPVTA peptide of the gp100.
• Description: Biotinylated Human HLA-A*03:01&B2M&gp100 (ALLAVGATK) Complex Protein (HLG-H82E3) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Thr 305 (HLA-A*03:01) & Ile 21 - Met 119 (B2M) & ALLAVGATK peptide (Accession # P04439 (HLA-A*03:01) & P61769 (B2M) & ALLAVGATK).
• Specifications: Biotinylated Human HLA-A*03:01&B2M&gp100 (ALLAVGATK) Complex Protein is produced by co-expression of HLA and B2M loaded with gp100 peptide. This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™). The protein has a calculated MW of 35.9 kDa and 11.7 kDa. The protein migrates as 40-43 kDa and 10 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
