  • Eliciting macroporosity in polyacrylamide and agarose

    Preparation of highly porous polyacrylamide has recently been described (Righetti et al., Electrophoresis, 1992, 13, 587–595). In this report we add new observations on the conditions of promoting macroporosity in polyacrylamide gels and extend the possibility of eliciting this phenomenon to agarose matrices by the combined use of polyethylene glycol and glycerol.

  • Running agarose and polyacrylamide gels

    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.
