Biotinylated Human HLA-A*11:01&B2M&KRASG12D (VVGADGVGK) Complex Protein is produced by co-expression of HLA and B2M loaded with KRASG12D peptide.
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 36.0 kDa and 11.7 kDa. The protein migrates as 40-45 kDa and 12 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
Passed as determined by the HABA assay / binding ELISA.
Less than 1.0 EU per μg by the LAL method.
>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.
