Chelex extraction

Chelex extraction is a laboratory method used to isolate DNA from samples, such as blood or tissue. It involves mixing the sample with a special resin called Chelex that binds metal ions which can damage DNA. When heated, the Chelex resin helps break cell structures and releases DNA into solution. The process is quick and straightforward, removing many impurities and leaving behind purified DNA ready for analysis. Chelex extraction is commonly used because it is cost-effective, requires minimal equipment, and produces DNA suitable for various genetic tests.
