    Abstract. Agarose and polyacrylamide gel electrophoresis systems for the molecular mass-dependent separation of hyaluronan (HA) in the size range of approximately 5-500 kDa were investigated. For agarose-based systems, the suitability of different agarose types, agarose concentrations, and buffer systems was determined.

    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.
