Quality Assurance

 

Most of the plant cell lines have to be maintained by continuous sub-culturing. This causes the risk of culture loss by laboratory failure, contamination or genetic drift and complicates the use of time consuming and costly methods for regular characterization.

To minimize these dangers DSMZ runs two independent sets of the collection, each set handled by different technicians at different times using different media. Transfer is organized and recorded according to ISO 9001:2000 rules.

Periodically on a monthly basis cell lines in the different sets are compared and on a quarterly basis digital photos are taken and stored.

For further characterization HPLC fingerprint and RAPD techniques can be used.
