ABSTRACT:
The invention relates to preparing and/or supplementing a cell or tissue culture medium. In particular, said invention relates to a serum-free and/or protein-free cell culture medium comprising peptide fractions isolated from rapeseeds, in particular rapeseeds cakes. A method for the production of a cell culture comprising said peptide fractions and for the use thereof is also disclosed.
