The term "384-well" refers to a type of microplate used in laboratory settings, specifically for high-throughput screening and assays. Each plate contains 384 small wells, allowing researchers to conduct multiple experiments simultaneously. This format is efficient for testing various samples or conditions, making it popular in fields like biotechnology and pharmaceutical research. 384-well plates are typically made from materials like polystyrene and can be used for various applications, including cell culture, enzyme assays, and DNA analysis. Their design enables automated liquid handling systems to dispense reagents accurately, enhancing the speed and reliability of experimental results.
