蛋白结构（Molecular Characterization）
Biotinylated Cynomolgus Mafa-A1*063:01&B2M&RM9 (RPKVPLRTM) Complex Protein is produced by co-expression of Mafa-A1 and B2M loaded with RM9 peptide.
This protein carries a flag tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 35.8 kDa and 13.8 kDa. The protein migrates as 40-43 kDa and 12 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
标记（Labeling）
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
蛋白标记度（Protein Ratio）
Passed as determined by the HABA assay / binding ELISA.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
纯度（Purity）
>90% 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.
