Human HLA-A*02:01&B2M Tetramer Protein is assembled by biotinylated monomer (HLM-H82W3) and streptavidin.
Biotinylated Human HLA-A*02:01&B2M Complex Protein is produced by co-expression of HLA and B2M. Biotinylated Human HLA-A*02:01&B2M Complex Protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 36.3 kDa and 11.7 kDa. The protein migrates as 40-43 kDa and 10 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
>90% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
