表达区间及表达系统（Source）

Biotinylated Human HLA-DRA1*01:01&HLA-DRB1*15:01&MBP (ENPVVHFFKNIVTPR) Complex Protein (HLM-H82Ea) is expressed from human 293 cells (HEK293). It contains AA Ile 26 - Glu 216 (HLA-DRA1*01:01) & Gly 30 - Lys 227 (HLA-DRB1*15:01) & ENPVVHFFKNIVTPR peptide (Accession # CAI2388006.1 (HLA-DRA1*01:01) & CAI2388008.1 (HLA-DRB1*15:01) & ENPVVHFFKNIVTPR).

Predicted N-terminus: Ile 26 & Glu

蛋白结构（Molecular Characterization）

Biotinylated Human HLA-DRA1*01:01&HLA-DRB1*15:01&MBP (ENPVVHFFKNIVTPR) Complex Protein is produced by co-expression of HLA-DRA1 and HLA-DRB1 loaded with MBP peptide.

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).

The protein has a calculated MW of 29.8 kDa and 29.2 kDa. The protein migrates as 37-40 kDa and 32-37 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.
