Description
Agarose suitable for general analytical and preparative electrophoreses procedures. Agarose is used to separate nucleic acids electrophoretically because agarose gels have larger pore sizes than cross linked acrylamide gels at low concentrations. Agarose gels tend to be more solid, but less elastic, than cross-linked acrylamide gels. Agarose gels are also used in immunoelectrophoresis (IEP) and double-diffusion Ouchterlony plates to demonstrate antibody-antigen reactions. Used in chromatographic separations by either beading the agarose or cross-linking it. Also to make gel plates or overlays for cells in tissue culture.
