Coffea arabica DNAx: low concentration, low purity Nanodrop ND-1000 Spectrophotometer setup nucleic acid DNA-50 blank: 1.5 μL CE buffer samples 1.5 μL Results All 260/230 and all but one 260/280 ratios below 1.8 (low purity) Most probably poor sample quality (leaves molded, black) and samples were also unsufficiently ground.
