“From our collaborations with scientists, it’s clear that a better
approach to bioanalysis sample preparation is needed for therapeutic
proteins. Today's methods are fraught with variability due to a lack of
The kits are also expected to allow biopharmaceutical scientists to more easily deploy methods to contract organizations as well as transfer methods from one laboratory to another.
Precise Protein Digestion with ProteinWorks eXpress™ Digest Kits
ProteinWorks eXpress Digest Kits contain pre-measured, lot-traceable reagents, a 96-tube flexible sample collection module and easy-to-follow protocols enabling reproducible, fast digestion and accurate, sensitive protein quantification in both immunopurified and whole, non-immunopurified plasma and serum samples. The ProteinWorks product portfolio includes an optional, optimized µElution™ SPE kit and protocol designed to increase assay sensitivity, reduce matrix interferences, and improve LC-MS system robustness.
The exceptional reproducibility of the ProteinWorks Kits suggests that a high degree of intra- and inter-laboratory standardization is achievable - making method transfer easier and more successful.

Protein Bioanalysis by LC-MS
Bioanalysis with liquid chromatography (LC) and mass spectrometry (MS) determines drug concentrations in biological fluids yielding data about the time course of a drug's action in the body.
With emphasis on the process of getting biotherapeutic proteins to patients faster, Waters continues to focus on the needs of patients and improving healthcare delivery with novel pre-analytic solutions and LC-MS instrumentation that empower laboratories to tackle the complexity and challenges of large molecule quantification.
