Study Notes
Bioassay Purpose and Concepts
- The primary purpose of a bioassay is to determine the potency or concentration of a substance, such as a drug or hormone, by measuring its effect on living organisms or tissues.
Dose-Response Curve
- A dose-response curve in bioassay is a graphical representation of the relationship between the dose of a substance and the resulting biological response or effect.
Endpoint in Bioassay
- An endpoint in bioassay refers to the specific biological response or effect being measured, such as death, growth, or changes in behavior.
- An example of an endpoint commonly used in bioassays is lethality, where the dose of a substance required to cause death in a certain percentage of test organisms is measured.
Advantage of Bioassay over Chemical Analysis
- An advantage of using a bioassay over chemical analysis to measure potency is that bioassays can detect the biological activity of a substance, which may not be fully captured by chemical analysis.
