Genetic Stability Testing

Genetic stability testing (cell line stability) verifies that the expression system has not undergone any changes that would impact the integrity of the product. It is a key component in characterizing production cell banks and is critical in maintaining quality assurance of biologicals derived from bacterial, yeast and mammalian cell cultures.

Genetic stability testing services include:

  • Restriction enzyme analysis by Southern Blot
  • Gene copy number by QPCR
  • Expression Cassette Sequencing
  • Fluorescence In Situ Hybridization (FISH)  – gene mapping
  • Karyology – classical & spectral
