What is the Origin of Potency Assay?

This term originates in pharmaceutical quality control and bioassay development, where measuring biological effect, rather than just mass, is necessary for biologics and hormones. It reflects the need to test function in vivo or in vitro using responsive biological systems.

What is the Mechanism of Potency Assay?

The mechanism involves exposing a responsive biological system—like a cell line expressing a specific hormone receptor or an animal model—to serial dilutions of the test substance. The resulting biological response, such as receptor activation or hormone secretion, is then compared against a known reference standard to calculate the relative potency, often expressed in International Units (IU) or similar biological units. This validates the therapeutic concentration.

Potency Assay

Meaning

A potency assay is a quantitative biological test designed to determine the effective strength or biological activity of a substance, such as a therapeutic peptide or hormone preparation, rather than just its chemical purity. In hormonal wellness, this ensures that administered compounds elicit the expected physiological effect at the stated dose, which is crucial for managing sensitive endocrine systems. This measurement confirms functional equivalence.

Numerous pharmaceutical vials, containing precise liquid formulations, represent hormone optimization and metabolic health solutions. These sterile preparations are critical for peptide therapy, TRT protocols, and cellular function in the patient journey.
