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.

Blue-OUT™ is a unique product that washes the interfering Coomassie and fluorescent protein stains from gel pieces prior to their treatment for protein sequencing or mass spectrometry.   Also supplied in the InGel™ Blue kit for the tryptic digestion and peptide extraction of Cooma..

SG-Chymotrypsin (Human, Recombinant)™ is recombinant human chymotrypsin expressed in E. coli and purified by HPLC method. Chymotrypsin hydrolysis at the carboxyl side of aromatic amino acid residues including Tyrosine, phenylalanine and Tryptophan. Cleavage occurs at lower rate at Leucine and..
$0.00
SG-Chymotrypsin™ is a serine endopeptidase, which predominantly cleaves peptide bonds on the carboxy side of tyrosine, phenylalanine and tryptophan. In addition, chymotrypsin has a low catalytic activity against the carboxy side of leucine, methionine, alanine, aspartic and glutamic acids. It ..
