蛋白结构(Molecular Characterization)

Human HLA-A*02:01&B2M&MAGE-A4 (KVLEHVVRV) Tetramer Protein is assembled by biotinylated monomer and streptavidin.

Biotinylated Human HLA-A*02:01&B2M&MAGE-A4 (KVLEHVVRV) Complex Protein is produced by co-expression of HLA and B2M loaded with MAGE-A4 peptide. Biotinylated Human HLA-A*02:01&B2M&MAGE-A4 (KVLEHVVRV) 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, 13.3 kDa and 11.7 kDa. The protein migrates as 40-45 kDa, 15 kDa and 13 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>95% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.
