Explanation:
The sample is first denatured followed by the gel electrophoresis. Animal derived or synthetic antibody is produced which has the ability to bind to the protein.
The electrophoresis membrane is then washed by primary antibody before the excess antibody is washed off.
Then the secondary antibody is added to get attached to the primary antibody and then it can be visualized by immunofluorescence or some other method.
Most living things do not leave fossils behind because we decompose before we are covered by sediments. Fossils are formed when plant or an animal dies and is buried in mud. So this does not tend to happen as often.
