For Lot Release of viral vectors, specific tests such as Replication Competent assays are required to address safety concerns caused by the potential outcome of recombination events.

AAV

  • Interference and positive controls at two levels
  • cell-based assay for amplification, qPCR detection of DNA sequence
  • Custom or semi-custom assay development capability

Lenti

  • Culture or qPCR techniques
  • Minimum of 5 passages on permissive cell line including positive, negative, and spike control
  • Supernatant testing either 5% or 300 mL, whichever is less
  • Vector producing or ex vivo transduced cell testing – 1% of total or 108 whichever is less
