Each vial content 20 ug of the product.
Is Product T6567, Trypsin from porcine pancreas, TPCK treated?
The product has been treated with TPCK to remove chymotryptic activity, further purified through affinity chromatography, and lyophilized, resulting in convenient use and highly specific cleavage. This information is on the product page under application.
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.
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.
