2.5 Comprehensive
Nonreplicating Stress
Deconvolution
1. See Subheading 2.1, items 1–15.
2. NR deconvolution base medium: Prepare 500 mL of NR complete medium as described in Subheading 2.1, item 12 (for
M. tuberculosis wild type) or Subheading 2.1, item 13 (for
M. tuberculosis ΔpanCDΔlysA) with the following modifications: do not adjust pH and omit adding butyrate and NaNO 2 .
3. NR deconvolution media A–H: Aliquot 40 mL of NR deconvolution base medium into 8 Â 50 mL sterile tubes labeled A–
H. Add 20 μL of 99% w/v butyrate to appropriate tubes
according to Table 2. Adjust pH of all tubes to 5.0 or 7.0
according to Table 2. Filter sterilize all eight deconvolution
media. NaNO 2 is added to appropriate deconvolution media at
0.5 mM immediately prior to initiating experiment.

3. One or more of the following control compounds: rifampicin,
isoniazid, ethionamide, ethambutol, streptomycin, kanamycin,
and/or para-aminosalicylic acid at 10 mM in DMSO.
2.10 Data Analysis
1. Data analysis software such as Microsoft Excel, Prism 6.0
(GraphPad), or Collaborative Drug Discovery (CDD).
2. See Subheading 2.4 for CFU assays.
