Title |
DsigB_replicate1 |
Sample type |
SRA |
|
|
Source name |
10403S isogenic mutant
|
Organism |
Listeria monocytogenes |
Characteristics |
strain: 10403S lacking sigB
|
Treatment protocol |
RNAProtect bacterial reagent (Qiagen, Valencia, CA) was added according to the manufacturer’s instructions to the cultures grown to stationary phase; treated cells were stored at -80ºC (for no longer than 24 h) until RNA isolation was performed.
|
Growth protocol |
Bacteria were grown in 5 ml Brain Heart Infusion (BHI) broth (BD Difco, Franklin Lakes, NJ) at 37ºC with shaking (230 rpm) for 15 h, followed by transfer of a 1% inoculum to 5 ml pre-warmed BHI. After growth to OD600 ~ 0.4, a 1% inoculum was transferred to a 300 ml nephelo flask (Bellco, Vineland, NJ) containing 50 ml pre-warmed BHI. This culture was incubated at 37ºC with shaking until cells reached stationary phase (defined as growth to OD600 = 1.0, followed by incubation for an additional 3 h). Two independent growth replicates and RNA isolations were performed for each strain.

Extracted molecule |
total RNA |
Extraction protocol |
Bacterial cells were treated with lysozyme followed by 6 sonication cycles at 18W on ice for 30s. Total RNA was isolated and purified using the RNeasy Midi kit (Qiagen) according to the manufacturer’s protocol; RNA molecules <200 nt in length are not recovered well with this procedure, according to the manufacturer. RNA was eluted from the column using RNase-free water. Total RNA was incubated with RQ1 DNase (Promega, Madison, WI) in the presence of RNasin (Promega) to remove remaining DNA. Subsequently, RNA was purified using two phenol-chloroform extractions and one chloroform extraction, followed by RNA precipitation and resuspension of the RNA in RNAse free TE (10 mM Tris, 1 mM EDTA; pH 8.0; Ambion, Austin, TX). UV spectrophotometry (Nanodrop, Wilmington, DE) was used to quantify and assess purity of the RNA.
