Dear all. I would like to perform a biomass analysis of plant tissues. I need, basically, to determine in a quantitative way the amount of starch, cell wall, nucleic acids, proteins, lipids, soluble metabolites, total content of carbon, total content of nitrogen. I have funds to perform this analysis, but need to perform than in the next 30-45 days (at least have the samples being analyzed). The number of samples is around 36, including Arabidopsis and other 2 species of similar size. I do not have students to go abroad to run the analysis nor have anyone in here to analyze mass spectra results, so they should come interpreted. Many thanks.
