      Description
      OverviewA chemically modified trypsin that is resistant to autolysis and degradation. Trypsin specifically hydrolyzes amides, peptides and proteins at the C-terminus side of arginine and lysine residues. This mass spectrometry grade trypsin is methylated, TPCK treated, and affinity purified. It is specifically designed for digestion of proteins for sequencing and peptide fragment analysis by mass spectrometry. A trypsin to protein ratio of 1:100 to 1:20 is recommended for mass spectrometry protocols. Note: 1 SET = 5 X 20 µg of modified trypsin, and 1 ml of resuspension buffer.

      DescriptionA chemically modified trypsin that is resistant to autolysis and degradation. Trypsin specifically hydrolyzes amides, peptides and proteins at the C-terminus side of arginine and lysine residues. This mass spectrometry grade trypsin is methylated, TPCK treated, and affinity purified. It is specifically designed for digestion of proteins for sequencing and peptide fragment analysis by mass spectrometry.
      FormLyophilized
      Recommended reaction conditions
      Materials Provided: • Trypsin, Porcine, MS Grade (Kit Component No. KP31816-20UG): 5 vials, 20 µg each • Trypsin Resuspension Buffer (Kit Component No. KP31854-0.5ML): 1 vial, 0.5 ml Preparation Before Use: Before opening the trypsin centrifuge the tube at 15,000 x g for 5 min. Suspend the MS Grade Trypsin in the Trypsin-Suspension Buffer. Recommended reconstitution concentration 0.5-1 µg/µl. IMPORTANT NOTE: In some cases, after reconstitution, there is insoluble material, which is a non-protein and will not interfere with trypsin activity. If you prefer to remove it, centrifuge the tube briefly and transfer the supernatant to a clean tube. Guidelines for use: For mass spectrometry sequence analysis, MS Grade Trypsin to protein ratio of 1:20 to 1:100 is recommended. Use freshly reconstituted MS Grade Trypsin in any sequence analysis. Any unused trypsin may be stored at -70°C and used within two weeks. Avoid repeated freeze-thaw cycle after re-suspension, which may lead to performance loss. Any available protocol can be used for digestion of proteins with MS Grade Porcine Trypsin.
