A "96-well" plate is a flat plastic plate used in laboratories for various experiments, particularly in biology and chemistry. It contains 96 small wells arranged in an 8x12 grid, allowing researchers to conduct multiple tests simultaneously. Each well can hold a small volume of liquid, making it efficient for high-throughput screening. These plates are commonly used in applications like enzyme-linked immunosorbent assays (ELISA), cell culture, and DNA amplification. They are compatible with automated systems and can be used with various detection methods, such as fluorescence and absorbance, to analyze samples quickly and accurately.
