Recombinant Human HLA-A*02:01&B2M&PRAME (ALYVDSLFFL) Tetramer Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus, tetramer is assembled by biotinylated monomer and streptavidin.It contains Gly25-Thr305 (HLA-A*02:01), Ile21-Met119 (B2M) and ALYVDSLFFL 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.
