  8. How can we get Trypsin sequence information for Product T6567, Trypsin from porcine pancreas?

    If you are looking for trypsin sequence information, you have to go to the NCBI Protein Data Bank.

  9. How can we digest protein using Product T6567, Trypsin from porcine pancreas?

    As per Sigma R and D the information is as follows: In order to efficiently digest a protein with trypsin, it must be denatured and the disulfide bonds modified by reduction and alkylation, or at least reduced. Many intact proteins are highly resistant to digestion with trypsin. If you do not want to reduce and alkylate, you can then just boil the protein with 5 mM DTT or 20 mM 2ME for 10 minutes, and then quickly cool on ice to denature the protein. This may result in a precipitate, but the trypsin will still digest the protein and it will clear within an hour or two. You can also dissolve the protein in 6 M guanidine-HCl or 8 M urea. Reduce and alkylate using the PROT-RA kit or other suitable method. Then they would have to dilute the solution to less than 2 M of either denaturant and then add the trypsin. This is the method that we use routinely in the lab.

Evaluation of Recombinant, Chemically Treated Trypsin in Proteomics and Protein Characterization Assays

The field of proteomics is continually looking for new ways to investigate protein dynamics within complex biological samples. Recently, many researchers have begun to use RNA interference (RNAi) as a method of manipulating protein levels within their samples, but the ability to accurately determine these protein amounts remains a challenge. Fortunately, over the past decade, the field of proteomics has witnessed significant advances in the area of mass spectrometry. These advances, both in instrumentation and methodology, are providing researchers with sensitive assays for both identification and quantification of proteins within complex samples. This discussion will highlight some of these methodologies, namely the use of Multiple Reaction Monitoring (MRM) and Protein-AQUA.
