Figure 2. DNA amount measured at 260 nm after DNA extractions (a: van Soolingen procedure, b: Invisorb Spin Tissue Mini Kit from Invitek, c: PowerSoil DNA isolation Kit from MoBio) from big (+++: 10 log₁₀ cells), medium (++: 9 log₁₀ cells), and small (+: 8 log₁₀ cells) pellets of MAP K-10 (A, n=54), and M. tuberculosis H37Ra (B, n=54) cells.

Error bars are standard deviation. LOQ are limit of quantification of the spectrophotometer.
