FIELD: biotechnology.
SUBSTANCE: methods for production of a target antibody with modulated galactosylation (versions), methods for modulation of the target antibody galactosylation (versions) by culture medium optimisation are provided. The methods provide increasing the osmolality of the solution for culturing animal cells and/or asparagine addition to the solution at a certain point in time of the cell culturing process.
EFFECT: obtaining of the desired antibody population.
