Can FBS be used longer than the expiration date?

0

Possibly. While we guarantee FBS from five years from the date of processing, it is most likely viable for several years past that, assuming that it has been stored properly (at -20°C or below), and not subject to multiple thawing/refreezing cycles. We recommend that you performance-test the FBS before usage to confirm viability. If you do not have a protocol for doing so, please contact us for one. In addition, while is is not necessary for unopened and properly stored FBS, you may also consider sterile re-filtration (0.1 um) before performance-testing, especially if storage and handling conditions are uncertain.
