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™ .
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.
SG-Lysine-C™ endopeptidase, from Lysobacter enzymogenes, is a serine protease highly specific in cleaving peptide bonds at the carboxy side of lysine. Highly purified preparations of SG-Lysine-C™ are chemically modified making the enzyme resistant to autolysis and stabilizing its enzymat..

Trypsin is a serine protease that cleaves peptides on C-terminal end of lysine and arginine amino acid residues. The pH optimum of trypsin is pH 7.0-8.0. Trypsin is inhibited by serine protease inhibitors including TLCK (N-p-tosyl-L-lysine chloromethyl ketone), PMSF (phenylmethanesulfonyl fluoride),..

Gene/Protein:
G-Biosciences Immobilized Soybean Trypsin Inhibitor (STI) resin is designed for the efficient removal of trypsin, chymotrypsin and elastase proteases from protein digests. The action of the Immobilized STI resin will stop enzymatic reactions, in addition to removing the proteases and simplifying the..
