TMB (Soluble Substrate)

Affinity Electrophoresis as a Method for Determining Substrate-Binding Specificity of Carbohydrate-Active Enzymes for Soluble Polysaccharides

Affinity electrophoresis is a simple and rapid tool for the analysis of protein-binding affinities to soluble polysaccharides. This approach is particularly suitable for the characterization of the carbohydrate-active enzymes that contain

High-Throughput Tetramethylbenzidine (TMB) Screen for Peroxidases

Peroxidases catalyze the decomposition of hydrogen peroxide coupled to the oxidation of a variety of organic and inorganic substrates. Produced by a broad variety of natural sources, most peroxidases use heme or vanadium as a cofactor

底物 substrate

接受酶的作用引起化学反应的物质称为该酶（或其酶的反应）的底物。例如淀粉是淀粉酶的底物。过氧化氢是过氧化氢酶的底物。酶反应为可逆时，生成物也是逆反应的底物。此外辅酶也是酶的底物之一。有时候称代谢的起始物质为底物，例如某微生物的呼吸底物、发酵底物等。
