蛋白结构（Molecular Characterization）

PE-Labeled Human HLA-E*01:03&B2M Tetramer Protein is assembled by biotinylated monomer (HLM-H82Eg) and PE-labeled streptavidin.

Biotinylated Human HLA-E*01:03&B2M Monomer Protein is produced by co-expression of HLA and B2M. This Protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
