General description
Trypsin is applicable for tissue disaggregation, due to its effective action and tolerance towards different cell type and serum-induced neutralization.
Application
For trypsin digestion of peptides, use a ratio of about 1:100 to 1:20 for trypsin:peptide. The typical use for this product is in removing adherent cells from a culture surface. The concentration of trypsin necessary to dislodge cells from their substrate is dependent primarily on the cell type and the age of the culture. Trypsins have also been used for the re-suspension of cells during cell culture, in proteomics research for digestion of proteins and in various in-gel digestionsns†. Additional applications include assessing crystallization by membrane-based techniques and in a study to determine that protein folding rates and yields can be limited by the presence of kinetic traps.
Trypsin from porcine pancreas has been used to digest chicken bones. It has also been used in the isolation of luteal endothelial cells.
Biochem/physiol Actions
Trypsin cleaves peptides on the C-terminal side of lysine and arginine residues. The rate of hydrolysis of this reaction is slowed if an acidic residue is on either side of the cleavage site and hydrolysis is stopped if a proline residue is on the carboxyl side of the cleavage site. The optimal pH for trypsin activity is 7-9. Trypsin can also act to cleave ester and amide linkages of synthetic derivatives of amino acids. EDTA is added to trypsin solutions as a chelating agent that neutralizes calcium and magnesium ions that obscure the peptide bonds on which trypsin acts. Removing these ions increases the enzymatic activity.
Serine protease inhibitors, including DFP, TLCK, APMSF, AEBSEF, and aprotinin, amongst others, will inhibit Trypsin.

Preparation Note
This product is a lyophilized powder soluble in Hank′s Balanced Salt Solution at 25 mg/mL.
For applications that require EDTA, solubilizing trypsin should be done with a buffered salt solution contaiing no Ca2+ or Mg2+.

Other Notes
One BAEE unit will produce a ΔA253 of 0.001 per min at pH 7.6 at 25° C using BAEE as substrate. One BTEE unit = 320 ATEE units. Reaction volume = 3.2 mL (1 cm light path).
Trypsin consists of a single chain polypeptide of 223 amino acid residues, produced by the removal of the N-terminal hexapeptide from trypsinogen which is cleaved at the Lys - lle peptide bond. The sequence of amino acids is cross-linked by 6 disulfide bridges. This is the native form of trypsin, beta-trypsin. BETA-trypsin can be autolyzed, cleaving at the Lys - Ser residue, to produce alpha-trypsin. Trypsin is a member of the serine protease family.
Disclaimer
Solutions in 1 mM HCl are stable for 1 year in aliquots and stored at -20°C. The presence of Ca2+ will also diminish the self-autolysis of trypsin and maintain its stability in solution. Trypsin will also retain most of its activity in 2.0 M urea, 2.0 M guanidine HCl, or 0.1% (w/v) SDS.
