DefiniGEN Ltd., and Atelerix Ltd., today announced they have successfully shipped in vitro liver models from the UK to a top tier pharma customer in the US. The agreement between the companies combines DefiniGEN’s mechanistically relevant iPSC hepatocytes (Opti-Heps) with Atelerix’s hydrogel preservation technology, which prevents loss of function and enables even sensitive samples to remain stable at ambient temperatures for up to two weeks.
