The separated molecules are transferred or blotted onto a second matrix, generally a nitrocellulose or polyvinylidene difluoride (PVDF) membrane.ģ- Blocking nonspecific sites: The membrane is blocked to prevent any nonspecific binding of antibodies to the surface of the membrane.Ĥ- The transferred protein is then probed with a combination of antibodies: one antibody specific to the protein of interest (primary antibody) and another antibody specific to the host species of the primary antibody (secondary antibody). Your sample could be tissue, cells, or another solution that you want to extract and analyze its protein.Ģ- Electrophoretic separation of proteins: The procedure is to separate the macromolecules in a sample using gel electrophoresis. Western Blotting Stepsġ- The first step in a western blotting is preparing samples: The samples are prepared and loaded onto a gel. Proteins that are resolved on sodium dodecyl sulfate- polyacrylamide gel electrophoresis (SDS-PAGE) gels are typically transferred to adsorbent membrane supports under the influence of an electric current in a procedure that is known as Western blotting (WB) or protein blotting. The transfer of proteins or nucleic acids to microporous membranes is referred to as “blotting” and this term encompasses both “spotting” (manual sample deposition) and transfer from planar gels.
