Synonyms

HLA-E*0103 & B2M & CMV UL40 (VMAPRTVLL)

Source

Unconjugated HLA-E*01:03 & B2M & CMV UL40 (VMAPRTVLL) Complex Protein (HL0-H52E3) is expressed from human 293 cells (HEK293). It contains AA Gly 22 - Ile 305 (HLA-E*01:03) & Ile 21 - Met 119 (B2M) & VMAPRTVLL peptide (Accession # P13747 (HLA-E*01:03) & P61769-1 (B2M) & VMAPRTVLL).

Predicted N-terminus: Gly 22 & Val

Molecular Characterization

Unconjugated HLA-E*01:03 & B2M & CMV UL40 (VMAPRTVLL) Complex Protein is produced by co-expression of HLA-E*01:03 and B2M loaded with CMV UL40 peptide.

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™), and it is not biotinylated.

The protein has a calculated MW of 36.2 kDa and 13.7 kDa. The protein migrates as 38-43 kDa and 12 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
