How long can you keep prepared TAE buffer?

Prepared TAE buffer can be stored at room temperature for up to a month, but it is best kept in the refrigerator for longer shelf life, typically up to six months. It's important to store it in a clean, airtight container to prevent contamination. Always check for any signs of contamination or precipitate before use, as these can impact experimental results. If in doubt, it's best to prepare fresh buffer.
