chymotrypsin lyophilized powder / recombinant human chymotrypsin for mass spectrometry
Chymotrypsin / Recombinant Chymotrypsin / Enzyme / RCT / peptide mapping
DESCRIPTION
Chymotrypsin Enzyme
Chymotrypsin is a recombinant serine endopeptidase expressed in E.coli, purified with HPLC, the
gene sequence is same as that human chymotrypsin. The recombinant chymotrypsin hydrolyzes at the
carboxyl side of aromatic amino acids: Tyr, Phe and Trp. Cleavage may also be observed, but at a
lower rate, at Leu and Met. Chymotrypsin activity is optimal in the pH range of 7.0–9.0. This sequencing
grade enzyme can be used alone or in combination with other proteases to produce protein digests for
peptide mapping applications or protein identification by peptide mass fingerprinting or MS/MS spectral
matchingIt is suitable for digestion reactions in-solution or in-gel.
ADVANTAGES
Animal origin free:The use of recombinant chymotrypsin eliminates the content of other proteins, the
risk of virus presence, and other potential adventitious agents found in animal-derived chymotrypsin.
Stable:A sterile recombinant chymotrypsin lyophilized powder eliminates the contamination risks and
decreases the chance of activity loss in the process of transport and storage.
High purity:1.Recombinant Chymotrypsin provides increased specificity and eliminates
contaminating activities found in enzymes purified from pancreas.
2.No anion trypsin or cation trypsin.
3. One single main band at 25kD by SDS-PAGE.
SPECIFICATION
Serine endopeptidase that specifically hydrolyzes peptide bonds at the C-termini of Tyr, Phe, and Trp.
Leu, Met, Ala, Asp, and Glu are cleaved at a lower rate. Acts also upon amides and esters of susceptibl
amino acids.
APPLICATION
Hydrolysis of proteins by chymotrypsin alone or in combination with other proteases. Suitable for peptide
mapping, fingerprinting, and sequence analysis.
For peptide digestion, use a ratio (w/w) of approximately 1:60 for chymotrypsin:peptide. Perform peptide
digests in 100 mM Tris HCl containing 10 mM CaCl2, pH 7.8, at 30 °C. Self digestion may occur if
temperatures above 37 °C are used. A known peptide such as melittin should be used as a control for all
Experiments.
