pubmed:abstractText |
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 nitrilotriacetic acid. This staining has the potential for complete reversibility using stronger chelating agents such as EDTA or diethylenetriaminepentaacetic acid, to allow for recovery of the protein. Specific staining produces an intense luminescent signal from those metal-binding proteins which have been modified either chemically or via site-directed mutagenesis. Gels were photographed using a time-resolved fluorescence camera system.
