GC Enhancer Buffer VERY useful. Shorter fragments? <2-3kb? May or may not need GC enhancer -> Lowers accuracy (a bit). LOW template amount (0.1 to 0.5 ng/25 . uL. PCR reaction) -> Make it easier for the . Simply put, gel electrophoresis is a technique used to separate molecules such a DNA, RNA and proteins according to size.. Requires an electric current as these molecules are negatively charged. We’ll be looking at separating long strands of DNA into smaller fragments..
