Product Description
Product Name Vesicular Stomatitis Virus (VSV) Pseudotyped with SARS-CoV-2 Spike Glycoprotein, HexaPro-Stabilized Trimer (United Kingdom Variant, N501Y)
Description Recombinant VSV pseudotyped with SARS-CoV-2 spike glycoprotein, engineered with HexaPro mutations (K986P, V987P, F817P, A892P, A899P, A942P) to stabilize the spike protein in its antigenically optimal pre-fusion conformation. The construct includes the N501Y mutation (B.1.1.7/Alpha lineage) and features a furin cleavage site modification (RRAR→GSAS). Produced in HEK293T cells and purified for high-quality pseudovirus preparations.
Key Features
  • Spike Stabilization: HexaPro mutations enhance pre-fusion stability for consistent antigen presentation.
  • Variant-Specific Mutation: Contains the N501Y substitution (UK/Alpha variant).
  • Furin Site Modification: RRAR→GSAS mutation abolishes furin-mediated cleavage.
  • Reporter Gene: Encodes enhanced green fluorescent protein (EGFP) for rapid infectivity quantification.
Applications
  • Neutralizing antibody screening against SARS-CoV-2.
  • Evaluation of vaccine-elicited immune responses.
  • Viral entry mechanism studies and inhibitor assessment.
