Recombinant Biotinylated Human HLA-A*02:01&B2M&PRAME (SLLQHLIGL) 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 SLLQHLIGL peptide. PRAME (PReferentially expressed Antigen in MElanoma) is a melanoma-associated antigen expressed in cutaneous and ocular melanomas and some other malignant neoplasms, while its expression in normal tissue and benign tumors is limited.
