The goal of this stage is to introduce methyl groups that will modify and protect naturally occurring EcoRI sites in the double-stranded cDNA. - [Read Construction of cDNA Libraries Protocol.]
Protocol describes monosaccharide analysis by methanolysis. The method gives more complex chromatograms than the corresponding alditol acetate method, because up to four methyl glycosides can be produced from each monosaccharide. However, the method is easier to perform. - [Read Monosaccharide Analysis by Methanolysis Protocol]
The activity of ß-glucuronidase (GUS) can be accurately determined in intact plant tissue using 4-methylumbelliferyl ß-D-glucuronide (4-MUG) as a substrate. Upon hydrolysis by GUS, the fluorochrome 4-methyl umbelliferone (4-MU) is produced. This method is based on the permeability of both 4-MUG and 4-MU through plant tissue. It consists of incubation of the tissue with the reagent and quantification of the fluorescence emitted by 4-MU in the solution. GUS activity in each sample can be... - [Read Quantitative GUS Activity Assay in Intact Plant Tissue Protocol]
