Comparison of yield and purity of RNA samples prepared by EMNE, F&T, and BPC method.

aThe RNA purity was estimated by calculating the ratio between the absorbance at 260 nm and 280 nm. bThe RNA concentration was quantified using a spectrophotometer at 260 nm. cThe cultured cells were harvested from culture of 3 ml (BPC & F&T methods) and 1 ml (EMNE method for B. braunii), respectively.
