| Description | DescriptionClostripain also known as Clostridiopeptidase B or Endoproteinase Arg-C is a proteinase that cleaves peptide bonds on the carboxyl side of arginine. This protein is a heterodimer composed of a heavy and a light chain that are held together via strong noncovalent forces. As a proteolytic DescriptionClostripain also known as Clostridiopeptidase B or Endoproteinase Arg-C is a proteinase that cleaves peptide bonds on the carboxyl side of arginine. This protein is a heterodimer composed of a heavy and a light chain that are held together via strong noncovalent forces. As a proteolytic enzyme it can be used for isolation of various cell types by tissue dissociation.Clostripain exists in two different forms, an oxidized, native condition and a reduced activated form that differ in enzymatic activity. The native clostripain can be activated with reducing agents (e.g. DTT, Cysteine) resulting in a higher activity of the enzyme.ApplicationClostripain NB is used in combination with Collagenase NB 1 and/or Neutral Protease NB, suitable for cell isolation from various tissue types.SpecificationsContains chromatographically highly purified clostripain.Clostripain, native state activity: ≥ 5.0 U/mg (BAEE)Clostripain, activated activity: ≥ 50.0 U/mg (BAEE)Clostripain activity, native state, per vial: ≥ 200 U/vial (BAEE)Clostripain activity, activated, per vial: statusEC 3.4.24.3 • Mr ca. 59 000 • CAS [9028-00-6]References and DefinitionsUnit definition:Clostripain, native state (BAEE assay): 1 Unit catalyzes the cleavage of 1 µmol Nα-Benzoyl-L-arginine ethyl ester per minute at 25 °C, pH 7.8.Clostripain, activated (BAEE assay): 1 Unit catalyzes the cleavage of 1 µmol Nα-Benzoyl-L-arginine ethyl ester per minute at 25 °C, pH 7.8.
