Used primarily in molecular biology for gel electrophoresis, it is ideal for separating large DNA fragments due to its low gelling and melting temperatures. It is also employed in techniques like pulsed-field gel electrophoresis and for creating gels that can be easily remelted without damaging sensitive biomolecules. Additionally, it finds application in cell culture as a matrix for 3D cell growth and in microbiology for embedding microorganisms without harming them. Its biocompatibility makes it suitable for drug delivery systems and tissue engineering scaffolds.
