Extracted RNA yield and purity. Yield and absorption ratios for the different extraction methods were determined. For each method, 6 cyanobacteria aliquots were used for RNA extraction and 1 μl analysed using the NanoDrop ND-1000 UV/Vis spectrophotometer. The resulting bars shown are the average, and the standard deviation, from values obtained for each extraction method.
