Electroblotting is a method in molecular biology/biochemistry/immunogenetics to transfer proteins or nucleic acids onto a membrane by using PVDF or nitrocellulose, after gel electrophoresis.  The protein or nucleic acid can then be further analyzed using probes such as specific antibodies, ligands like lectins, or stains. This method can be used with all polyacrylamide and agarose gels. An alternative technique for transferring proteins from a gel is capillary blotting. @BiologicalLifesciences
