Study Notes
Bioassay Definition
- Bioassay is a method to estimate the concentration or potency of a substance by observing its effects on a biological system.
Types of Bioassays
- Direct Assays: Directly measure a specific response caused by the substance.
- Indirect Assays: Based on either quantitative or quantal (all-or-none) responses. Quantitative responses are measurable while quantal measure the presence or absence of a response.
Applications of Bioassays
- Standardization: Used to standardize drugs, toxins, and other substances when chemical methods are unavailable or inadequate.
- Clinical Diagnosis: Can assist in diagnosing medical conditions.
- Scientific Necessity: Necessary when the active components of a substance are unknown or hard to isolate chemically.
Accuracy Comparison
- Bioassays are generally less accurate than chemical assays.
