Mass Spectrometry & Sequencing

We offer a variety of reagents for mass spectrometry and sequencing including mass spectrometry grade Trypsin and highly purified preparations of other proteases, including SG-Lysine-C.

Our InGel is a highly reliable method for the proteolytic digestion of proteins in gel for subsequent analysis by mass spectrometry. InGelArray is also available for high throughput in gel digestion of protein spots for mass spectrometry. FOCUSFASTsilver produces crystal clear backgrounds and maximal peptide recovery needed for critical analysis by mass spectrometry.


A large selection of mass spectrometry and sequencing accessories are also available. Our Proteomic Grade Water removes contamination worries and improves reliability of 2D gel analysis. Trypsin Digestion Mix provides optimal buffered conditions for in gel trypsin digestion. Proteomic grade microfuge tubes can also be found among our accessories.
