Enzyme Assays - Preferred

Concept UI	M0534301
Scope note	Methods used to measure the relative activity of a specific enzyme or its concentration in solution. Typically an enzyme substrate is added to a buffer solution containing enzyme and the rate of conversion of substrate to product is measured under controlled conditions. Many classical enzymatic assay methods involve the use of synthetic colorimetric substrates and measuring the reaction rates using a spectrophotometer.
Preferred term	Enzyme Assays
Entry term(s)	Assay, Enzymatic Assay, Enzyme Assays, Enzymatic Assays, Enzyme Enzymatic Assay Enzymatic Assays Enzyme Assay

Indirect Enzyme Assays - Narrower

Concept UI	M0534302
Scope note	Sensitive detection methods using enzymes to indirectly measure substances that would normally be difficult to quantitate.
Preferred term	Indirect Enzyme Assays
Entry term(s)	Assay, Indirect Enzymatic Assay, Indirect Enzyme Assays, Indirect Enzymatic Assays, Indirect Enzyme Enzymatic Assay, Indirect Enzymatic Assays, Indirect Enzyme Assay, Indirect Enzyme Assays, Indirect Indirect Enzymatic Assay Indirect Enzymatic Assays Indirect Enzyme Assay
