Our Quality Control Process

A standard-setting, industry-leading QC testing process validates our virus stocks.

What We Do

We produce virus stocks with the highest sequence fidelity in the industry, ensuring unparalleled reproducibility across production lots. This is achieved through our rigorous QC process and reverse genetics based manufacturing approach.

The result? Virus products of unmatched quality and consistency, setting a new standard for R&D. Empower your researchers, save time, and maximize your R&D investments with our virus stocks.

We perform the following tests on every manufactured virus stock -

  • Virus titer per mL – Plaque assay/TCID50/IFA
  • Genome copy number per mL – qPCR/ddPCR
  • Next generation sequencing (NGS):
    1. Complete viral genomic sequence compared to reference sequence.
    2. Additional data on diversity of sequence reads and SNP frequency.
    3. Contamination analysis.
  • Mycoplasma test – PCR test
  • Sterility test for bacterial contamination
  • Endotoxin test
  • Virus stock purity test – Silver stain or PAGE Gel
  • Documentation:
    1. Cell line information
    2. Passage history of virus sequence
    3. Experimental conditions
    4. Documentation of reagents used during manufacture and QC testing.

For full transparency, we provide all QC data for every virus stock to our customers.

Our QC standard: Each virus stock available for sale demonstrates a 99.9-100% sequence match to the input reference sequence used in the reverse genetics system during manufacturing.
