counterions, gel electrophoresis

Using the gel electrophoresis device, I found the simple concept not so simple. This was using Agarose gel analysis. Agarose with a direct current, is the most commonly used method for analyzing DNA fragments between 0.1 and 25 kb, while pulse-field gel electrophoresis enables analysis of DNA fragments up to 10,000 kb. Our experiment usedContinue reading “counterions, gel electrophoresis”
