Enjoy all of the advantages of Proteomics Grade Trypsin in a 15-minute digestion. A staple of MS sample preparation, efficient tryptic digestion is essential to successful proteomic analyses. While traditional digests require up to 18 hours, the same digest can be accomplished in only 15 minutes using the Trypsin Spin Column, Proteomics Grade.
This ultra-micro spin column contains highly purified, TPCK-treated porcine trypsin immobilized on a spherical 20 micron silica support, chemically modified to minimize non-specific adsorption. This product is ideal for rapid protein digestion of small volumes (100 μl or less). Eluted peptides are ready for MS analysis, and require no additional clean-up.

"Multi-stage" search strategies have become widely accepted for peptide identification and are implemented in a number of available software packages. We describe limitations of these strategies for validation and decoy-based statistical analyses and demonstrate these limitations using a set of
Enzymes of the Rnf family are believed to be bacterial redox-driven ion pumps, coupling an oxidoreduction process to the translocation of Na+ across the cell membrane. Here we show for the first time that Rnf is a flavoprotein, with FMN
To study the endogenous counterpart of LEC-6, a major galectin in Caenorhabditis elegans, the proteomic analysis of glycoproteins captured by an immobilized LEC-6 column was performed using the nano liquid chromatography-tandem mass spectrometry (LC-MS/MS) technique. A protein recovered in a

Proteomics-based quantification methods for differential protein expression measurements are among the most important and challenging techniques in the field of mass spectrometry. Though numerous quantification methods have been established, no method meets all the demands for measuring accurate protein expression

This work uses electrospray ionization mass spectrometry (ESI-MS) in conjunction with hydrogen/deuterium exchange (HDX) and optical spectroscopy for characterizing the solution-phase properties of cytochrome c (cyt c) after heat exposure. Previous work demonstrated that heating results in irreversible denaturation for
