蛋白结构(Molecular Characterization)

Biotinylated Human HLA-A*11:01&B2M&KRAS (VVVGAGGVGK) 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 39-43 kDa and 10 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.

HLA-A*1101 & B2M & KRAS (VVVGAGGVGK) ELISA

Immobilized Biotinylated Human HLA-A*11:01&B2M&KRAS (VVVGAGGVGK) Complex Protein (Cat. No. HLS-H82E6) at 1 μg/mL (100 μL/well) on streptavidin (Cat. No. STN-N5116) precoated (0.5 μg/well) plate can bind Mouse Anti-B2M antibody, Human IgG1 with a linear range of 0.1-2 ng/mL (Routinely tested).

Protocol

 

背景(Background)

The Kirsten rat sarcoma 2 viral oncogene homolog (KRAS) oncogene plays a critical role in the initiation and maintenance of pancreatic tumors and its signaling network represents a major target for therapeutic intervention. The Alex Fluor 647 labeled Human HLA-A*1101 KRAS (VVVGAGGVGK) complex protein is a complex of HLA-A*1101 of the MHC Class I, B2M, and VVVGAGGVGK peptide of the KRAS.
