Recombinant Biotinylated Human HLA-A*02:01&B2M&MAGE-A4 or MAGE-A8 (KVLEHVVRV) Monomer Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus.It contains Gly25-Thr305(HLA-A*02:01), Ile21-Met119(B2M) and KVLEHVVRV peptide. MAGE-A4 and MAGE-A8 are type I membes of the melanoma associated antigen (MAGE) family. The MAGE family is a large, highly conserved group of proteins that share a common MAGE homology domain. Both MAGE-A4 and MAGE-A8 antigen-presenting peptides can be presented by HLA-A*02:01.
