Featured testing–Trace elements

Increase control and visibility to the trace element profile of your cell culture media and feeds. Proactively track historical trends and create predictive media formulations, all with a goal to reduce lot-to-lot variability.

Our trace element testing helps create greater understanding of which trace elements your specific process or cell line may be most sensitive to. This data can provide an edge to increase your bioproduction success.


Unexpected sources of key driver trace elements have been identified in all classes of raw materials. Our trace elemental testing service offers QC validated* tests on finished good media (11 trace elements) and cell culture raw materials (16 trace elements). Services are offered on catalog and custom formulations (AGT, DPM, and liquid). Our technical team can also collaborate with customers on a case-to-case basis, to characterize cell culture media and manage raw material variability. For more details contact:
