Product overview
Recombinant PE-Labeled Human HLA-A*02:01&B2M&PRAME (SLLQHLIGL) Tetramer Protein is expressed from HEK293 with His tag and Avi tag at the C-terminus. PE-Labeled Human HLA-A*02:01&B2M&PRAME (SLLQHLIGL) Tetramer is assembled by biotinylated monomer and PE-labeled streptavidin. It contains Gly25-Thr305 (HLA-A*02:01), Ile21-Met119 (B2M) and SLLQHLIGL peptide (accession: A0A140T913(HLA-A*02:01) & P61769(B2M) &SLLQHLIGL).

Data Display
1E6 of PRAME specific TCR-HEK293T cell line were stained with 100ul of 10ug/ml PE-Labeled Human HLA-A*02:01&B2M&PRAME (SLLQHLIGL) Tetramer (Cat. No.MHC-HM443TP) and non-transfected HEK293T cells and PE-Labeled protein were used as negative control. The binding activity was evaluated by PE signal. (QC Test)
Immobilized PE-Labeled Human HLA-A*02:01&B2M&PRAME (SLLQHLIGL) Tetramer, His Tag at 1μg/ml (100μl/well) on the plate. Dose response curve for HLA-A*02:01&B2M&PRAME TCR, hFc Tag with the EC50 of 46.9ng/ml determined by ELISA.
Background
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.
