Human HLA-A*03:01&B2M&KRAS (VVVGAGGVGK) Complex Protein (Monomer, MALS verified)

Synonyms

HLA-A*0301 & B2M & KRAS (VVVGAGGVGK)

Source

Human HLA-A*03:01&B2M&KRAS (VVVGAGGVGK) Complex Protein (HLS-H52H7) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Thr 305 (HLA-A*03:01) & Ile 21 - Met 119 (B2M) & VVVGAGGVGK peptide (Accession # P04439 (HLA-A*03:01) & P61769 (B2M) & VVVGAGGVGK).

Predicted N-terminus: Gly 25 & Ile 21

Molecular Characterization

Human HLA-A*03:01&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.

The protein has a calculated MW of 37.7 kDa and 15.7 kDa. The protein migrates as 42-45 kDa and 15 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Endotoxin

Less than 1.0 EU per μg by the LAL method / rFC method.

Purity

>90% as determined by SDS-PAGE.

>90% as determined by SEC-MALS.

Formulation

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