Synonyms

HLA-G & B2M & Peptide (RIIPRHLQL)

Source

Human HLA-G&B2M&Peptide (RIIPRHLQL) Tetramer Protein (HLG-H52E9) is expressed from human 293 cells (HEK293). It contains AA Gly 25 - Ile 308 (HLA-G) & Ile 21 - Met 119 (B2M) & RIIPRHLQL peptide (Accession # P17693-1 (HLA-G) & P61769 (B2M) & RIIPRHLQL).

Predicted N-terminus: Gly 25 & Arg

Molecular Characterization

Human HLA-G&B2M&Peptide (RIIPRHLQL) Tetramer Protein is assembled by biotinylated monomer (HLM-H82E4) and streptavidin.

Biotinylated Human HLA-G&B2M&Peptide (RIIPRHLQL) Complex Protein is produced by co-expression of HLA and B2M loaded with RIIPRHLQL peptide. Biotinylated Human HLA-G&B2M&Peptide (RIIPRHLQL) Complex Protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

The protein has a calculated MW of 36.3 kDa, 13.9 kDa and 13.3 kDa. The protein migrates as 42-45 kDa and 15 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

The protein is designed as a tetramer.
