Vaccine Laboratory Services

Q2 Solutions vaccine laboratory services are supported by global, comprehensive central laboratory services to meet your development needs across the entire vaccine development life cycle

Q2 Solutions’ vaccine laboratory is located in San Juan Capistrano, CA. Our ISO 9001 (2015) laboratory is ~12,000 Sq. ft and home to over 100 employees. Our main services include:
  • Lab services to support vaccine immunogenicity and efficacy studies
  • Viral and bacterial neutralization assays across multiple platforms: PRNT, RVP, microneutralization
  • Custom PCR development to support vector-specific detection
  • Immunoassay development in ELISA and Luminex platforms
  • Full range of lab services to support influenza vaccine trials  

With over 35 years of experience in clinical vaccine development, our experts help you select the custom assay level most suited to the clinical phase of your compound: Fit-for-purpose, Qualified, or Validated. We offer our experience in the following:
