Quality control and assay services

We develop, optimise and validate product-specific assays, enabling us to offer a complete range of analytical testing services. Using our quality control assays, we are able to establish identity, potency, purity and safety of your products. 

Our services include:

  • Agarose gel electrophoresis (AGE) for restriction mapping, Supercoiled content for plasmid DNA, ITR integrity for AAV plasmids
  • API 20E indexing
  • Cell Bank characterisation testing e.g. viability, purity, identity testing, plasmid retention
  • DNA sequencing to include genetic characterisation of rAAV
  • ELISA based assays for residual testing
  • Endotoxin testing
  • Fluorometric assays such as RibogreenTM
  • Protein Assays and characterisation e.g. micro-BCA assay, SDS-PAGE, IEF, Western Blotting
  • PCR – RAPD testing
  • Quantitative PCR (qPCR) for residual testing e.g. host cell genomic DNA and mycoplasma (in-process)
  • Spectrophotometry
