BIOLOGICAL ASSAYS Meaning and
Definition
-
Biological assays refer to experimental techniques used in the field of biology and medicine to measure and quantify the biological activity or response of a substance or organism. These assays are designed to assess the biological effects of different substances, such as drugs, hormones, toxins, enzymes, or other biological molecules, and determine their potency, efficacy, toxicity, or effects on living systems.
Biological assays can be conducted using various methods and techniques, including in vivo assays (performed in a living organism), in vitro assays (performed outside a living organism in controlled laboratory conditions), or ex vivo assays (performed outside an organism but using living cells or tissues). These assays often involve the use of specific bioassay systems, such as cell cultures, animal models, or biochemical tests.
The results of biological assays are measured by quantifying various biological endpoints, such as cell viability, enzyme activity, gene expression, receptor binding, or physiological responses. These measurements help researchers and scientists understand the interactions between substances and living systems, evaluate the effectiveness of drugs or treatments, assess the toxicity of chemicals or pollutants, and determine the mechanisms of action or biological pathways involved.
Overall, biological assays play a crucial role in the development of new drugs, evaluating the safety and efficacy of treatments, understanding biological mechanisms, and advancing our knowledge of living systems.

Etymology of BIOLOGICAL ASSAYS
The etymology of the word "biological" can be traced back to the Greek word "biologikos", which combines "bios" meaning "life" and "-logikos" meaning "related to study or theory". Therefore, "biological" refers to anything related to the study or theory of life.
The term "assay" has a Latin origin. It comes from the Latin word "exagium", meaning "weighing" or "balancing", which evolved into "assai" in Old French and "assay" in Middle English. Originally, assay referred specifically to the testing or assaying of the purity of precious metals, such as gold and silver.
When combined, "biological assays" refers to methods or techniques used to determine or measure the biological activity, potency, or concentration of a substance, such as a drug or hormone, in a living system.
