A METHOD OF DETERMINING A COMPOSITIONAL OR FUNCTIONAL CHARACTERISTIC OF A CELL CULTURE MEDIA

摘要

A method of determining variation between a query cell culture media and a reference cell culture media is provided. The method comprises the steps of incubating a reference cell with an aliquot of the query culture media and at least three chemical cell stressors in wells of a microtitre plate and determining an environmental response of the reference cell in the presence of the query cell culture media and each of the plurality of chemical cell stressors. A query cell culture media specific environmental response fingerprint is generated comprising the plurality of chemical cell stressor specific environmental responses. The query cell culture media- specific environmental response fingerprint is compared with a reference media-specific environmental response fingerprints corresponding to a reference cell culture media and generated using the reference cell. Variation between the query cell culture media and the reference cell culture media is then determined based on the level of correlation between the query cell culture media-specific environmental response fingerprint and the reference media- specific environmental response fingerprints.
