Background

TP53 has been recognized as a tumor suppressor. 50% of cancers carry a TP53 mutation while many others affect other pathway components. High-copy numbers of WT p53 peptide-MHC class I complexes were detected on tumor cells as compared to low copies on normal cells. The Human HLA-A*0201 p53 (HMTEVVRRC) complex protein is a complex of HLA-A*0201 of the MHC Class I, B2M, and HMTEVVRRC peptide of the p53.

Specifications

Biotinylated Human HLA-A*02:01&B2M&p53 (HMTEVVRRC) Complex Protein is produced by co-expression of HLA and B2M loaded with p53 peptide. This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™) . The protein has a calculated MW of 36.3 kDa and 11.7 kDa. The protein migrates as 38-43 kDa and 12 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
