Product introduction

Recombinant Biotinylated Human HLA-A*02:01&B2M&CMV pp65 (NLVPMVATV) Monomer Protein is expressed from HEK293 with His tag and Avi tag at the C-terminus. It contains Gly25-Thr305(HLA-A*02:01), Ile21-Met119(B2M) and NLVPMVATV peptide (accession: A0A140T913(HLA-A*02:01) & P61769(B2M) &NLVPMVATV).

Product details

Molecular aliases: MHC; HLA-A*02:01; CMV pp65
Protein length: Gly25-Thr305
Expression system: HEK293
Molecular weight: The protein has a predicted MW of 50.35 kDa. Due to glycosylation, the protein migrates to 53-63 kDa based on Bis-Tris PAGE result.
Purity: > 95% as determined by Bis-Tris PAGE > 95% as determined by HPLC
Endotoxin: Less than 0.01 EU per μg by the LAL method.
Formulation: Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
State: Lyophilized
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.
Reconstitution: Dissolve the lyophilized protein in distilled water. Please refer to the Certificate of Analysis for detailed instructions.

Background

Human cytomegalovirus (CMV) is one of the major causes of severe complications in immunocompromised patients, such as recipients of hematopoietic cells, solid organ transplantation, and HIV-infected individuals. CMV is also a major pathogen in congenital infection. It can cause life-threatening diseases and severe neurological sequelae in newborn infants. CMV phosphoprotein pp65 is thought to be a major antigen for CMV-specific cellular immunity.
