| Analysis Note: | Contaminant: <0.5% free 4-nitraniline |
| Application: | Use Chromozym® PK as a substrate for the determination of serine proteases, specifically plasma kallikrein in citrated plasma. |
| Biochem/physiol Actions: | Chromozym PK is cleaved by plasma kallikrein into a residual peptide and free 4-nitraniline, which is measured at 405 nm. The absorbance difference per minute is used for the determination of the kallikrein activity in U/ml. |
| General description: | Chromozym® PK is a non-radioactive amidolytic chromogenic substrate mostly used in kinetic analysis of plasma kallikrein. |
