表达区间及表达系统（Source）
Biotinylated Human HLA-A*11:01&B2M&KRAS (VVGAGGVGK) Complex Protein (HLS-H82E3) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Thr 305 (HLA-A*11:01) & Ile 21 - Met 119 (B2M) & VVGAGGVGK peptide (Accession # Q5S3G3-1 (HLA-A*11:01) & P61769 (B2M) & VVGAGGVGK).
Predicted N-terminus: Gly 25 & Ile 21
蛋白结构（Molecular Characterization）
Biotinylated Human HLA-A*11:01&B2M&KRAS (VVGAGGVGK) Complex Protein is produced by co-expression of HLA and B2M loaded with KRAS 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.
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.
