CNCM
Hybridoma bailment

Cell lines registration for regulatory purposes requires several procedures and validations (creation / validation of working and master bank, doubling time determination, etc.)..

As an expert of hybridoma handling, BIOTEM supports its customers in the recording process with specific institutions dedicated (French CNCM institute: Collection Nationale de Cultures de Micro-organismes for example).
