Characteristics
|
EnzyBeads™ Trypsine offers a broad range of applications including protein identification and protein sequencing studies. Trypsin cleaves peptide bonds at the carboxylic side of lysine and arginine residues, creating peptides in the size range required for mass spectrometry analysis. The optimal pH of trypsin is between 7 and 9. EnzyBeads™ Trypsine are able to digest large as well as very small quantities of proteins (e.g few nanograms). A sample version of EnzyBeads™ Trypsine can be provided for testing (10 digestions).
