Fig. 2From: A quantitative method to measure geranylgeranyl diphosphate (GGPP) and geranylgeranyl monophosphate (GGP) in tomato (Solanum lycopersicum) fruitChromatograms for GGPP and GGP at different pHs using an ethylene-bridged C18 column. A, D Chromatograms for GGPP and GGP at pH 2.7 (formic acid 0.05%); B, E chromatograms for GGPP and GGP at pH 5.8 (acetic acid 0.01% + 20 mM ammonium acetate); C, F chromatograms for GGPP and GGP at pH 10.0 (ammonia 0.05%). The organic mobile phase was acetonitrile in all casesBack to article page
