Popis: | A method is described for the rapid analysis of the nucleotides, guanosine 5′-diphosphate-3′-diphosphate (ppGpp) and guanosine 5′-triphosphate-3′-diphosphate (pppGpp), by high-performance liquid chromatography. It has been found that the inclusion of magnesium acetate in the potassium phosphate buffer facilitates elution of these highly phosphorylated compounds from the Partisil strong anion-exchange resin and allows their determination under isocratic conditions. The application of this methodology to formic acid extracts of bacterial cells is demonstrated. |
