Mitogenic compositions, a process for preparing them and their application to cell culture media.

摘要

The invention relates to mitogenic compositions and their preparation by extraction from a protein fraction of sera from animals, which are immunised or otherwise against antigens or haptens, by subjecting the sera to affinity chromatography in which the adsorbent carries antigens. Foetal calf serum, ovalbumin and glycine are used. Application to the preparation of cell culture media.
