蛋白结构（Molecular Characterization）
This protein carries a polyhistidine tag at the C-terminus.
Alexa Fluor 647-Labeled Human HLA-A*11:01&B2M&WT-1 (FSCRWPSCQK) Tetramer Protein is assembled by biotinylated monomer and AF647-labeled streptavidin.
Biotinylated Human HLA-A*11:01&B2M&WT-1 (FSCRWPSCQK) Complex Protein is produced by co-expression of HLA and B2M loaded with WT-1 peptide. Biotinylated Human HLA-A*11:01&B2M&WT-1 (FSCRWPSCQK) Complex Protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

背景（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 Biotinylated Human HLA-A*1101 WT1 (FSCRWPSCQK) complex protein is a complex of HLA-A*1101 of the MHC Class I, B2M, and FSCRWPSCQK peptide of the KRAS.
