ELISA Technologies for Microplates

Microplate readers measure the results of enzyme-linked immunosorbent assays or "ELISA" tests and other light absorption-based tests. ELISA assays form the basis of modern diagnostics testing and immunology research. In the simplest of terms, a sample is treated to a sequence of chemical processes, usual rinses, which are designed to generate a measurable color change to indicate the presence of a chemical of interest.  This color change is measured optically by a microplate reader. Many assays generate a color change that can be read by measuring the absorbance of the result at a specific wavelength. Other assays, such as fluorescent, may generate a fluorescent signal to be measured using a different technology.
