working principle of polyacrylamide linear polymer

  • Polyacrylamide Polymer - an overview | ScienceDirect Topics

    An electric field is applied to the gel and causes the proteins to migrate towards the other end of the strip. Individual proteins migrate until they reach their isoelectric point. In the second dimension, sodium dodecyl sulfate (SDS) polyacrylamide polymer networked gels are used. In this separation mechanism, the proteins are separated based upon size.
