Substrats d'enzymes
Les substrats enzymatiques sont des molécules sur lesquelles les enzymes agissent pour catalyser des réactions chimiques. Le substrat se lie au site actif de l'enzyme, où il subit une transformation spécifique pour former le produit de la réaction. Les substrats enzymatiques sont des outils essentiels dans la recherche pour étudier la cinétique enzymatique, la spécificité et le mécanisme d'action. Ils sont également utilisés dans les essais diagnostiques et les études biochimiques. Chez CymitQuimica, nous offrons une sélection diversifiée de substrats enzymatiques de haute qualité pour soutenir vos recherches en enzymologie et biochimie.

Dehydroluciferin
CAS :Dehydroluciferin is a synthetic analogue of luciferin, which is naturally found in fireflies. It has a high resistance to degradation by the target enzymes and is used as a substrate in chemiluminescent assays. Dehydroluciferin reacts with luciferase to produce light that can be measured using a photomultiplier tube. The light emission is proportional to the amount of enzyme activity present in the sample and may be used to determine the presence of specific enzymes in test samples. This compound also reacts with disulfide bonds, which are found in proteins, such as cytochrome P450, that are involved in metabolism.Formule :C11H6N2O3S2Degré de pureté :Min. 97.0 Area-%Masse moléculaire :278.31 g/molRef: 3D-W-201759
