BSL-2 Virology-Based Assays

Innovative virology research with safety and precision. At Vaxonyx LLC, we perform a wide range of BSL-2 level virology assays to support antiviral screening, vaccine research, and molecular pathogenesis studies. Our facility and expertise enable high-quality in vitro virology studies using established viral systems under biosafety level 2 (BSL-2) containment.

Virus Culture and Quantification

  • Virus propagation in mammalian and insect cell lines
  • Plaque assay, TCID₅₀, and focus-forming assays
  • Viral load quantification by qPCR and immunodetection methods
  • Determination of infectious titer and replication kinetics

Antiviral Efficacy and Cytotoxicity Testing

  • In vitro antiviral compound screening and dose–response analysis
  • Determination of EC₅₀, CC₅₀, and Selectivity Index (SI)
  • Time-of-addition and mechanism-of-action studies
  • Cytotoxicity and cell viability assays (MTT, LDH, ATP-based)

Immunological and Molecular Virology Assays

  • ELISA for viral antigen or antibody detection
  • Immunofluorescence and immunocytochemistry
  • Flow cytometry-based infection quantification
  • qRT-PCR for viral RNA and host response genes

Recombinant and Pseudovirus Systems

  • Development and testing of pseudotyped virus models
  • Safe surrogate systems for studying high-risk viral entry pathways
  • Evaluation of vaccine candidates, neutralizing antibodies, and entry inhibitors

Data Analysis and Reporting

  • Statistical analysis of viral growth and inhibition curves (GraphPad Prism, R, Python)
  • Interpretation of antiviral and immunological response data
  • Custom visual data reports and summaries for publication or regulatory use

Applications

  • Vaccine antigen discovery and characterization
  • Antiviral drug screening and mechanistic studies
  • Host-pathogen interaction and immune response profiling
  • Support for IND-enabling preclinical studies
