Elizabeth Blackwell was accepted by accident at Hobart College (then Geneva Medical College). The dean and faculty that evaluated potential students put her candidacy up for a vote with the 150 men currently enrolled.
An assay is an investigative (analytic) procedure in laboratory medicine, pharmacology, environmental biology and molecular biology for qualitatively assessing or quantitatively measuring the presence or amount or the functional activity of a target entity (the analyte). Enzyme activity assay: Enzymes may be tested by their highly repeating activity on a large number of substrates when loss of a substrate or the making of a product may have a measurable attribute like color or absorbance at a particular wavelength or light or chemiluminiscence or electrical/redox activity.
Bioassay (commonly used shorthand for biological assay or assessment), or biological standardization is a type of scientific experiment.A bioassay involves the use of live animal or plant (in vivo) or tissue or cell (in vitro) to determine the biological activity of a substance, such as a hormone or drug.n this type of bioassay, response of the test substance taken first and the observed response is tried to match with the standard response. Several responses of the standard drug are recorded till a close matching point to that of the test substance is observed. A corresponding concentration is thus calculated.
