Watch the recording of this webinar here: https://bit.ly/2Y05bV4 The first step to avoiding an unpleasant and costly contamination event is characterization of your cell banks. Regardless of the biotech product, careful characterization of the cell banks used in its production is the first step in mitigating the risk of a contamination event. In fact, cell line characterization is an important component of the overall viral safety strategy for the product. We will describe the testing necessary to ensure cell banks are free from infectious and other adverse agents and that meets current regulatory expectations. Different levels of testing are performed for master, working, and end of production cell banks, and the differences in testing for each of these types of banks will be discussed. In this webinar, you will learn: • The types of tests that are needed to fully characterize your cell banks • The best tests to use for your particular cell line • Reasons why a viral contaminant may be missed
