HLA-DPA1*0103 & HLA-DPB1*0401 & CLIP (PVSKMRMATPLLMQA)

Source

Biotinylated Human HLA-DPA1*01:03&HLA-DPB1*04:01&CLIP (PVSKMRMATPLLMQA) Complex Protein (HLP-H82Ea) is expressed from human 293 cells (HEK293). It contains AA Ala 29 - Glu 222 (HLA-DPA1*01:03) & Arg 30 - Lys 225 (HLA-DPB1*04:01) & PVSKMRMATPLLMQA peptide (Accession # P20036 (HLA-DPA1*01:03) & P04440 (HLA-DPB1*04:01) & PVSKMRMATPLLMQA).

Predicted N-terminus: Ala 29 & Pro

Molecular Characterization

Biotinylated Human HLA-DPA1*01:03&HLA-DPB1*04:01&CLIP (PVSKMRMATPLLMQA) Complex Protein is produced by co-expression of HLA-DPA1*01:03 and HLA-DPB1*04:01 loaded with CLIP peptide.

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

The protein has a calculated MW of 29.5 kDa and 29.2 kDa. The protein migrates as 38-41 kDa and 33-36 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

Labeling

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

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.

バックグランド

HLA-DP is a isotype of MHC Class II responsible for presenting foreign antigens to the immune system's helper T-cells. The CLIP peptide, derived from the invariant chain, occupies the peptide-binding groove of the newly synthesized HLA-DP molecule to prevent it from loading irrelevant peptides inside the cell.
