Cell line authentication

For biocompatibility assays and the cellasys #8 protocol we use the L929 cell line. As a prerequisition for reliability of data, our cell line was recently analysed by the Leibniz-Institut DSMZ-Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH. Please find the species identification in our quality management section.

Animal Experimentation: Working Towards a Paradigm Change

Workshop und deutsche Buchpremiere am 14. und 15. Juni in München Tierversuche zählen zu den umstrittensten Praktiken, in denen wir Tiere nutzen, insbesondere weil den Tieren hier absichtlich Schmerzen, Leiden und Schäden zugefügt werden – mit der Begründung eines möglichen Erkenntnisgewinns für den Menschen. An dieser Rechtfertigung für die Unerlässlichkeit von Tierversuchen hat sich wenig […]
