A bioassay is an analytical method to determine the concentration or potency of a substance by its effect on living animals or plants (in vivo), or on living cells or tissues(in vitro). A bioassay can be either quantal or quantitative, direct or indirect. If the measured response is binary, the assay is quantal, if not, it is … See more A bioassay is a biochemical test to estimate the potency of a sample compound. Usually this potency can only be measured relative to a standard compound. A typical bioassay involves a stimulus (ex. drugs) … See more Direct assay In a direct assay, the stimulus applied to the subject is specific and directly measurable, and the response to that stimulus is … See more Environmental bioassays are generally a broad-range survey of toxicity. A toxicity identification evaluation is conducted to determine what the … See more The first use of a bioassay dates back to as early as the late 19th century, when the foundation of bioassays was laid down by German physician Paul Ehrlich.
