Human HLA-DQA1*03:02&DQB1*03:03 Monomer Protein (Peptide free)

Synonyms

HLA-DQA1*03:02 & DQB1*03:03

Source

Human HLA-DQA1*03:02&DQB1*03:03 Monomer Protein (HL3-H5285) is expressed from human 293 cells (HEK293). It contains AA Glu 24 - Glu 217 (HLA-DQA1*03:02) & Arg 33 - Lys 230 (HLA-DQB1*03:03) (Accession # AAU88001.1 (HLA-DQA1*03:02) & AAA59755.1 (HLA-DQB1*03:03)).

Molecular Characterization

Human HLA-DQA1*03:02&DQB1*03:03 Monomer Protein, produced by co-expression of HLA-DQA1*03:02 and HLA-DQB1*03:03, has a calculated MW of 27.7 kDa (HLA-DQA1*03:02) and 30.2 kDa (HLA-DQB1*03:03). Subunit HLA-DQA1*03:02 is fused with a polyhistidine tag at the C-terminus and subunit HLA-DQB1*03:03 is fused with a twin strep tag at the C-terminus. The reducing (R) protein migrates as 33-42 kDa due to glycosylation.
