Calculate specific activity of enzyme
Specific enzyme activity (usually stated simply as ‘specific activity’) is the number of enzyme units per ml divided by the concentration of protein in mg/ml. Specific activity values are therefore quoted as units/mg or nmol/min/mg (if unit definition B is applied). Specific activity is an important measure of enzyme … See more Enzymology would be less complicated if everyone used the same unit definition. A standard unit definition is given below: 1 unit (U) is the amount of enzyme that catalyses the … See more Activity is quoted in units per ml (U/ml), in other words nmol per min per ml (if unit definition B has been adopted). Thus activity values … See more The activity value (units/ml) for your enzyme is the most important parameter when you are developing an assay. This is because the volume (i.e. number of units) that you add will … See more In this section we discuss why one enzyme may have different measured activity values in different labs. By this we mean real differences in measured activity, not apparent differences caused by the use of … See more WebJan 16, 2024 · Enzyme activity is the amount of substrate converted by the enzyme in moles per unit time. It measures the amount of active enzyme present in a mixture at a given time. On the other hand, specific activity is the activity of the enzyme per mg of total enzyme. It measures the purity of the enzyme in a mixture.
