    2012-12-15 · Agarose gels have a large range of separation, but relatively low resolving power. By varying the concentration of agarose, fragments of DNA from about 200 to 50,000bp can be separated using standard electrophoretic techniques. SDS PAGE uses an anionic detergent (SDS) to denature proteins and the protein molecules become linearized.
