What is bioassay and types of bioassay?
Bioassay is Assessment of a biological substance. Bioassay or biological standardization is a type of scientific experiment typically conducted to measure the effects of a substance on a living organism and is essential in the development of new drugs and in monitoring environmental pollutants.
What are the different types of bioassay?
There are two types of bioassays: (1) direct assays and (2) indirect assays. In direct assays, the doses of the standard and test preparations are “directly measured” for (or until) an “event of interest”.
How do you use bioassay?
Bioassays are procedures which estimate the amount of radioactive material deposited in the body, either by direct measurement, using sensitive x-ray detectors placed over the chest (lung counting) and/ or other organs, or by detection of radioactivity in the excreta (feces and urine).
What is the principle of bioassay?
4. The basic principle of bioassay is to compare the test substance with the International Standard preparation of the same and to find out how much test substance is required to produce the same biological effect, as produced by the standard.
What is the importance of bioassay?
Bioassays provide valuable information concerning the potency of biological products. This is essential for evaluating batch-to-batch consistency and stability. Bioassay data are crucial at all stages in the development of biological products, from early research work to final quality control of finished products.
What are the advantages of bioassay?
The advantages of modern high-throughput bioassays are their speed, efficiency, repeatability, and specificity.
What are the disadvantages of bioassay?
A disadvantage of animal bioassays as they are currently performed is that they generally are not designed specifically to provide information on biochemical and physiologic mechanisms operating during the production of tumors.
What is example of bioassay?
One well known example of a bioassay is the “canary in the coal mine” experiment. To provide advance warning of dangerous levels of methane in the air, miners would take methane-sensitive canaries into coal mines. If the canary died due to a build-up of methane, the miners would leave the area as quickly as possible.

Why do we perform bioassay?
The primary purposes of bioassays are to measure the pharmacological activity of new or chemically undefined substances, as well as to determine side-effect profiles, including toxicity.
