Human HLA-A*03:01&B2M&KRASG12C (VVVGACGVGK) Tetramer Protein

Human HLA-A*03:01&B2M&KRASG12C (VVVGACGVGK) Tetramer Protein

• Background: The Kirsten rat sarcoma 2 viral oncogene homolog (KRAS) oncogene plays a critical role in the initiation and maintenance of pancreatic tumors and its signaling network represents a major target for therapeutic intervention. The Human HLA-A*0301 KRASG12C (VVVGACGVGK) complex protein is a complex of HLA-A*0301 of the MHC Class I, B2M, and VVVGACGVGK peptide of the KRASG12C.
• Description: Human HLA-A*03:01&B2M&KRASG12C (VVVGACGVGK) Tetramer Protein (HLC-H52H9) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Thr 305 (HLA-A*03:01) & Ile 21 - Met 119 (B2M) & VVVGACGVGK peptide (Accession # P04439 (HLA-A*03:01) & P61769 (B2M) & VVVGACGVGK).
• Specifications: Human HLA-A*03:01&B2M&KRASG12C (VVVGACGVGK) Tetramer Protein is assembled by biotinylated monomer (HLC-H82E3) and streptavidin. Biotinylated Human HLA-A*03:01&B2M&KRASG12C (VVVGACGVGK) Complex Protein is produced by co-expression of HLA and B2M loaded with KRASG12C peptide. Biotinylated Human HLA-A*03:01&B2M&KRASG12C (VVVGACGVGK) Complex 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, 13 kDa and 10 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
