We’ve put a new spin on a classic sample prep technique with over 100 years of history, precipitation. Our solutions combine innovative protein precipitation protocols with the ProTrap XG tool to deliver high purity, high yield, and highly consistent samples, ideal for downstream mass spectrometry analysis.


In protein analysis, it is well recognized that mass spectrometry data is only as good as the samples used. Highly pure samples yield better outcomes and promote longevity in instrument life span.

With sample preparation playing such a critical role in both top-down and bottom-up protein analysis workflows, Proteoform Scientific is committed to answering the unmet needs in generating high purity samples.
