A microtiter plate is a flat plate with multiple wells used for conducting various laboratory experiments, particularly in the fields of biochemistry and molecular biology. Each well can hold small volumes of liquid, typically ranging from a few microliters to several milliliters, allowing for high-throughput screening of samples. These plates are commonly made from plastic and can be designed to accommodate different types of assays. Microtiter plates come in various formats, such as 96-well, 384-well, or even 1536-well configurations, depending on the number of samples needed. They are often used in applications like enzyme-linked immunosorbent assays (ELISA), cell culture, and drug discovery, making them essential tools in research and clinical laboratories.
