Definition
manufacturing process related impurity role held by a material entity that originates from an acellular material component of a cell culture
Explanatory Notes
Cell culture-derived impurity role applies to impurities that originate from acellular materials present in or used to maintain a cell culture, such as media components, media supplements, inducers, antibiotics, surfactants, antifoam agents, selection agents, or other culture additives. These materials may remain in downstream or later manufacturing intermediates after harvest or purification. This role excludes materials originating from the production cells or host cell line itself, such as host cell proteins, host cell DNA, cell debris, or other host-cell-derived material. The term cell culture-derived therefore refers to the culture environment and non-cellular materials present in that environment, not to cells, cell parts, or host-cell molecules.
Examples
- the cell culture-derived impurity role of residual insulin from a cell culture medium supplement remaining in a harvested process intermediate; the cell culture-derived impurity role of residual antibiotic from a selection medium remaining in a downstream intermediate; the cell culture-derived impurity role of residual antifoam agent carried from a bioreactor culture into a harvest pool; the cell culture-derived impurity role of residual surfactant from a culture medium additive detected in a process intermediate; the cell culture-derived impurity role of residual inducer used during recombinant protein expression and carried into a clarified harvest; the cell culture-derived impurity role of residual nutrient feed component remaining in a harvested cell culture fluid;
