Product overview
Recombinant PE-Labeled Human Peptide Ready HLA-A*03:01&B2M Tetramer Protein is expressed from HEK293 with His tag and Avi tag at the C-terminus. PE-Labeled Human Peptide Ready HLA-A*03:01&B2M Tetramer is assembled by biotinylated monomer and PE-Labeled streptavidin. It contains Gly25-Thr305(HLA-A*03:01) and Ile21-Met119(B2M) (accession: NP_002107.3(HLA-A*03:01) & P61769(B2M)).

Background
Peptide Ready HLA-A*03:01&B2M Tetramer is absent from peptide, namely peptide-receptive MHC. It can be loaded with antigenic peptides matching HLA-A*03:01. Peptide ready MHC molecules comprising human HLA alleles and B2M, which can be readily tetramerized and loaded with peptides of choice in a high-throughput manner.
