Product Description

Cat

IMP-1681

Official Symbol

HLA-A

Product Overview

Recombinant Human HLA-A Tetramer protein(NY-ESO-1)(A0A140T913(HLA-A*02:01)&P61769(B2M)&SLLMWITQV)(Gly25-Thr305(HLA-A*02:01),Ile21-Met119(B2M) and SLLMWITQV peptide) is expressed from Expi293 with His tag and Avi tag at the C-terminal,tetramer is assembled by biotinylated monomer and streptavidin.

Expression System

HEK293

Species

Human

Tag

C-His-Avi Tag

Form

Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

Molecular Mass

The protein has a predicted MW of 258 kDa. Due to glycosylation, the protein migrates to 260-265 kDa under Non reducing (N) condition based on Tris-Bis PAGE result.

Protein length

It contains Gly25-Thr305(HLA-A*02:01),Ile21-Met119(B2M) and SLLMWITQV peptide.

Endotoxin

Less than 1EU per μg by the LAL method.

Purity

> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC

Storage

-20 to -80°C for 12 months as supplied from date of receipt.
'-20 to -80°C for 3-6 months in unopened state after reconstitution.
4-8℃ for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles.U17

Reconstitution

Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended (usually we use 1mg/ml solution for lyophilization). Dissolve the lyophilized protein in distilled water.

SDS-PAGE

HPLC

Bioactivity-ELISA 1

Immobilized Human NY-ESO-1(HLA-A*02:01) Tetramer, His Tag at 5μg/ml (100μl/well) on the plate. Dose response curve for Anti-NY-ESO-1(HLA-A*02:01) Antibody, hFc Tag with the EC50 of 6.5ng/ml determined by ELISA.
