Biotinylated Human HLA-B*15:01&B2M&SARS-CoV-2 epitope (NQKLIANQF) Monomer Protein (MHC-HM448B) Summary

Product Description

Recombinant Biotinylated Human HLA-B*15:01&B2M&SARS-CoV-2 epitope (NQKLIANQF) Monomer Protein is expressed from HEK293 with His tag and Avi tag at the C-terminus.It contains Gly21-Thr301(HLA-B*15:01), Ile21-Met119(B2M) and NQKLIANQF peptide.

Product Background

HLA-B*15:01 is strongly associated with asymptomatic infection with SARS-CoV-2 and is likely to be involved in the mechanism underlying early viral clearance. T cells from pre-pandemic individuals carrying HLA-B*15:01 were reactive to the immunodominant SARS-CoV-2 S-derived peptide NQKLIANQF, and 100% of the reactive cells displayed memory phenotype.

> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin
Less than 1 EU per ug by the LAL method.
Form
Lyophilized
Shipping
Shipped at ambient temperature.
Formulation
Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution
Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
Stability And Storage
-20 to -80°C for 12 months as supplied from date of receipt.;-80°C for 3 months after reconstitution.;Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
