Recombinant PE-Labeled Human Peptide Ready HLA-A*11:01&B2M Tetramer-Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. PE-Labeled Human Peptide Ready HLA-A*11:01&B2M Tetramer is assembled by biotinylated monomer and PE-Labeled streptavidin.It contains Gly25-Thr305 (HLA-A*11:01) and Ile21-Met119 (B2M). Peptide Ready HLA-A*11:01&B2M Monomer is absent from peptide, namely peptide-receptive MHC. It can be loaded with antigenic peptides matching HLA-A*11:01. 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.
