Waters ProteinWorks Digest Kits

Waters has launched a new line of ProteinWorks digest kits that simplify, accelerate, and standardize the LC-MS quantification of proteins via the surrogate peptide approach. The kits contain pre-measured, lot-traceable reagents, a 96-tube flexible sample collection module, and easy-to-follow protocols. This enables 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.
