Biological Assays

Meaning

Biological assays are analytical procedures used to qualitatively or quantitatively measure the effect of a substance, such as a hormone, drug, or compound, on a living system, cell, or tissue. These controlled experiments are indispensable in endocrinology and pharmacology for determining the potency, efficacy, and concentration of bioactive molecules. They provide functional data on how a substance interacts with biological receptors or pathways, offering a dynamic view beyond simple structural analysis. Reliable bioassays are essential for standardizing hormone preparations and evaluating their clinical impact.
