Descrizione generale
Chymotrypsin Sequencing Grade is isolated as a specific protease in pure form from bovine pancreas.
Specificità
Serine endopeptidase that specifically hydrolyzes peptide bonds at the C-terminial of Tyr, Phe, and Trp. Leu, Met, Ala, Asp, and Glu are cleaved at a lower rate. Acts also upon amides and esters of susceptible amino acids. The specificity of Chymotrypsin Sequencing Grade is tested with melittin as a substrate.
Applicazioni
Use Chymotrypsin Sequencing Grade for the hydrolysis of proteins by chymotrypsin alone or in combination with other proteases. It is suitable for peptide mapping, fingerprinting, and sequence analysis.
Qualità
Purity: Free of impurities that may interfere with the specific cleavage or separation of peptides in reversed-phase HPLC.
Nota sulla preparazione
Working concentration: The recommended amount of enzyme is 1/200 to 1/20 of the quantity of protein by weight.
Storage conditions (working solution): 2 to 8 °C
A solution in 1 mM HCl can be stored for up to one week at 2 to 8 °C.
Inhibitors: Aprotinin, DFP, PMSF, phenothiazine-N-carbonyl chloride, TPCK, ZPCK, α2-macroglobulin, α1-antitrypsin, soybean trypsin inhibitor, and chymostatin. No inhibition by APMSF.

Ricostituzione
Dissolve lyophilized chymotrypsin sequencing grade in 1mM HCl. The proteins to be sequenced are dissolved in digestion buffer (100mM Tris-HCl, 10mM CaCl2, pH 7.8).

The protocol consists of running a native gel with in-gel digestion by proteases, subsequent mass spectrometrical determination of protein sequence and modifications, followed by electro-elution and conformational analysis using melting point and circular dichroism. Finally, the eluted protein is tested
