Detection of calcium binding proteins on polyacrylamide gels using time-resolved lanthanide luminescence photography.

Abstract excerpt

Methods were developed for using the luminescent lanthanides Tb3+ and Eu3+ for the specific staining of calcium-binding proteins, as well as the nonspecific staining of proteins, on polyacrylamide gels. These methods involve equilibration of the gel after electrophoresis in solutions containing the appropriate lanthanide and a weak competitive chelating agent, such as N-(2-hydroxyethyl)iminodiacetic acid or...
