Extraction contamination analysis. Absorption spectra in the UV-region for purified RNA using 6 different extraction methods. For each method, 6 cyanobacteria aliquots were used for RNA extraction. From all obtained RNA samples, 1 μl was analysed using the NanoDrop ND-1000 UV/Vis spectrophotometer. The resulting lines shown are averaged from values obtained for each extraction method.
