Chromogenic substrate s-2484
WebFeb 1, 2001 · Abstract. Background: Proteinase activities are often measured using chromogenic substrates that are much smaller than physiological substrates. Methods: The hydrodynamic size of macromolecular substrates (macrosubstrates) prepared by linking small chromogenic substrates to polyethylene glycol was determined by gel … WebUsing the chromogenic substrate S-2444, the spectrometric determination of urokinase (EC 3.4.21.31) in urine subjected to gel filtration was evaluated. Pure urokinase solutions were used to standardize analytical conditions. A low molecular mass (relative molecular mass < 5000) heat resistant (60 min, 97 degrees C) activity could be removed ...

WebApr 12, 2024 · In this work, the chromogenic reaction mechanism of wool was elucidated using free amino acids and the mixture as substrates. The oxidized products were characterized by IR, MALDI-TOF MS and LC-MS. The results indicate that the tyrosine or tryptophan could be oxidized by laccase, generating different radicals.
