uses of nonionic polyacrylamide and agarose gel

  • What is the difference between agarose and

    Agarose gels are used with DNA, due to the larger size of the biomolecules (DNA fragments are often thousands of kDa). For protein gels, polyacrylamide gives good resolution, as the far smaller size (50 kDa is typical) is more suited for the tighter intermolecular gaps of the gel.
