Agarose gel concentration

Tips to save agarose gel powder in high concentration agarose gels:

Agarose gel concentration is determined by the molecular size of DNA/RNA samples. For example, 0.8% agarose gel concentration should be used for Southern blot gels because genomic DNA are a group of very long DNA molecule mixture. On the other hand, PCR genotyping agarose gel concentration is usually much higher, such as 3%. The cost of agarose powder is not an issue if you run high agarose gel concentration once a month. But you just can not ignore its cost if you run high agarose gel concentration every day straight.
