A PCR plate is a specialized laboratory tool used in the process of Polymerase Chain Reaction (PCR). It is designed to hold multiple samples in small wells, allowing for simultaneous amplification of DNA. Typically made from materials like polypropylene, PCR plates are compatible with thermal cyclers, which are machines that control temperature changes necessary for the PCR process. These plates come in various formats, including 96-well and 384-well configurations, to accommodate different experimental needs. Each well is designed to minimize evaporation and contamination, ensuring accurate and reliable results. PCR plates are essential for applications in molecular biology, genetics, and diagnostic testing.
