Substratos enzimáticos
Substratos enzimáticos são moléculas sobre as quais as enzimas atuam para catalisar reações químicas. O substrato liga-se ao sítio ativo da enzima, onde passa por uma transformação específica para formar o produto da reação. Os substratos enzimáticos são ferramentas essenciais na pesquisa para estudar a cinética enzimática, especificidade e mecanismo de ação. Eles também são usados em ensaios diagnósticos e estudos bioquímicos. Na CymitQuimica, oferecemos uma seleção diversificada de substratos enzimáticos de alta qualidade para apoiar suas pesquisas em enzimologia e bioquímica.

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.Fórmula:C11H6N2O3S2Pureza:Min. 97.0 Area-%Peso molecular:278.31 g/molRef: 3D-W-201759
