A rapid and sensitive method of detecting pectinesterase activity following electrophoresis or isoelectric focusing in polyacrylamide gels is described. The method uses ruthenium red and requires no addition of substrate when making the gels, thus obviating direct enzyme-substrate contact during electrophoresis. Because of its versatility, the method can be(More)
Our objective was to evaluate the changes of mangrove forest coverage of Mexico and adjacent land cover types in the coastal zone between 1970 and 2005 by remote sensing techniques.
