A laboratory crosslinker is a specialised device used to create covalent bonds between molecules, typically through the use of UV light. This process, known as crosslinking, is essential for applications in molecular biology, biochemistry, and polymer science. Crosslinkers facilitate the bonding of DNA, RNA, or proteins to surfaces, membranes, or other molecules, enhancing the stability and functionality of the biomaterials. Commonly used in research labs, crosslinkers are crucial for procedures like DNA-protein interactions, immunoassays, and surface modifications. Their precise control over exposure time and intensity ensures accurate and reproducible results, making them indispensable for various scientific workflows.
