Following indicated culture conditions, HeLa-fR cells were washed 3 times with 1x PBS (pH 7.4).
Following indicated treatments, samples were incubated with the detection reagent for 1 h at 37°C and analyzed for fluorescence (Excitation: 508 nm and Emission: 527 nm).
Following indicated treatments, cells were washed thrice with ice-cold phosphate buffered saline (PBS) and lysed in ice-cold lysis buffer (50 mM Tris-Cl, pH 7.5, with 120 mM NaCl, 10 mM NaF, 10 mM sodium pyrophosphate, 2 mM EDTA, 1 mM Na3VO4, 1 mM PMSF, 1% NP-40 and protease inhibitor cocktail (Roche Diagnostics, Germany).
Following indicated treatment, C4-2B3 and C4-2B4 cells were stained with 1 μg/ml AO in complete media for 15 min, then washed with 1 × PBS, trypsinized, resuspended at 1 × 10 cells per ml cold 1 × PBS, and analyzed by flow cytometry.
Following indicated treatments, cells were washed thrice with ice-cold phosphate buffered saline (PBS) and lysed in ice-cold lysis buffer (50 mM Tris-HCl, pH 7.5, with 120 mM NaCl, 10 mM sodium fluoride, 10 mM sodium pyrophosphate, 2 mM EDTA, 1 mM sodium orthovanadate, 1 mM phenylmethylsulfonyl fluoride, 1% NP-40, and protease inhibitor cocktail).
Briefly, following indicated treatments, cells were trypsinized and incubated with 5 μM CM-H2DCFDA in PBS for 30 min in the 37°C incubator.
Any one of the following indicates active infection: A single ELISA test positive result, followed by a PCR positive result.

A visit to a Web site with a fiercely loyal following indicates that a growing number of people are downloading not just individual songs but entire albums, cover artwork and liner notes included, in less time and with less hassle than it would take to download the songs individually.
UPDATE 4: SpaceX CEO Elon Musk shared the following, indicating that the attempted recovery of the reusable stage one rocket failed – the rocket landed on the autonomous barge, but it impacted too hard to survive to be used again.
Hydrochemistry analysis indicates a high nitrate concentrations (discussed in the following), indicating that agricultural seepage is responsible for water quality degradation.
