Acrylamide solution is suitable for use in electrophoresis. It may be used in the preparation of gel buffer for the determination of molecular weight of polypeptide chains by polyacrylamide gel electrophoresis. It may be used in the electrochemical polymerization of pyrrole. It may be used to prepare the pH 7.6 gels, required for the determination of molecular weights of histone by sodium dodecyl sulfate gel electrophoresis.
