Signal/background ratios for OD and RFU readouts.

M. tuberculosis was grown in 96-well plates for the indicated length of time. Measurements were taken on days 3, 4, 5 and 6. Signal to background ratio was calculated by dividing the RFU or OD590 measurements from 80 test wells by the average signal in the background control wells containing 7H9-Tw-OADC plus 2% DMSO.

结核分枝杆菌（Mycobacterium tuberculosis）于96孔板中培养至指定时长。分别于第3、4、5、6天进行检测。信噪比（Signal-to-background ratio）通过以下方式计算：将80个检测孔的相对荧光单位（RFU，Relative Fluorescence Unit）或590纳米光密度（OD590，Optical Density at 590 nm）的检测值，除以含7H9-Tw-OADC与2%二甲基亚砜（DMSO，Dimethyl sulfoxide）的背景对照孔的平均信号值。
