Method Two complementary approaches were taken to quantify cytosolic and plastid ribosomes: The first approach used qRT–PCR. The second approach used relative quantitative proteomics based on emPAI values (Ishihama et al, 2005) to estimate the abundance of ribosomal proteins in the polysome gradient fractions.
