Protocol: Tox21 Assay Protocol Summary:

Two ul of enzyme-substrate mix was dispensed into medium binding white/solid 1536-well plates (Greiner Bio-One North America Inc., Monroe, NC) using a BioRaptr Flying Reagent Dispenser (FRD, Beckman Coulter, Brea, CA). Compounds dissolved in DMSO and positive control (furafyllline) were transferred to the assay plates at 23 nl using a Pintool station (Wako, San Diego, CA). The assay plates were incubated at room temperature for 10 min. Then 2 ul of NADPH regeneration solution was added to each well of the assay plates using an FRD and incubated at room temperature for 1 h. The reaction was stopped by adding 4 ul of detection reagent using an FRD and after 20 min incubation at room temperature the luminescence signal was measured using a ViewLux plate reader (Perkin Elmer, Shelton, CT). Data were expressed as relative luminescence units.

Comment: Disclaimer:

Although all reasonable efforts have been made to ensure the accuracy and reliability of the data, caution should be exercised when interpreting the results as artifacts are possible from nonspecific effects such as assay signal interference. The curve fitting and activity calls presented here are based on the NCATS analysis methods. Alternative analysis methods and interpretations of the data are available at EPA (http://actor.epa.gov) and NTP (http://tools.niehs.nih.gov/cebs3/ui/).

Compound Ranking:

1. Compounds are first classified as having full titration curves, partial modulation, partial curve (weaker actives), single point activity (at highest concentration only), or inactive. See data field "Curve Description". For this assay, apparent inhibitors are ranked higher than compounds that showed apparent activation.
2. For all inactive compounds, PUBCHEM_ACTIVITY_SCORE is 0. For all active compounds, a score range was given for each curve class type given above. Active compounds have PUBCHEM_ACTIVITY_SCORE between 40 and 100. Inconclusive compounds have PUBCHEM_ACTIVITY_SCORE between 1 and 39. Fit_LogAC50 was used for determining relative score and was scaled to each curve class' score range.

Protocol: The fix-reporter plasmid was conjugated into this strain which the stably integrates into the chromosome using the mini-Tn7 system (PMID: 15908923). This plasmid consists of the fixK promoter, which is a target of the fixLJ pathway driving expression of GFP.
The day before screen an overnight culture of B. multivorans strain VC7102, with fix reporter, is set up in tryptic soy broth (TSB) at 37 degrees C with shaking. The day of the screen the overnight culture is diluted 1:100 in fresh tryptic soy broth.
The day of the screen, 30 microL of tryptic soy broth (TSB) is pipetted into columns 1-22 of a 384-well plate (Corning 3764) using the Combi multidrop dispenser. To column 24, 30 microL of TSB containing 78 microM of Benserazide TSB is added for a positive control. To column 23, 30 microL of TSB containing with DMSO (0.078% v/v in TSB) is added for a negative control. 300 nL of each compound are pin-transferred to each plate. For every compound plate 2 replicate assay plates are set up. 30 microL of the 1:100 diluted-B. multivorans strain VC7102 is added to each well using the Combi. Initial OD600 and GFP are measured using the PerkinElmer EnVision. Plates are stacked 5 high, covered with lids and incubated at 37 degrees C overnight (~18 h).
The following day, assay plates are read using a PerkinElmer EnVision (600 nm filter and GFP).
Positive control: Benserazide 39 microM in column 24 (No positive control was used for plates 2089 & 2090; Plates 2091-2093: columns 1 & 24)
Negative control: DMSO 300 nL/well in column 23 (For plates 2089 & 2090 negative controls were located in columns 2 & 24; plates 2091-2093: columns 2 & 23)

Comment: Analysis method:
For each compound well, the initial GFP value was subtracted from overnight GFP value to calculate the deltaGFP. The mean and standard deviation of the negative control wells deltaGFP (column 23) on both replicate plates was calculated. Wells with replicate average deltaGFP at least 3 standard deviations above the plate negative control deltaGFP average were scored as potential positives.

To determine activity scores, Z-scores were calculated for each replicate separately based on the replicate negative control deltaGFP plate average and standard deviation. The replicate average deltaGFP Z-scores were used for activity scores, with activity score of 100 set to Z-score = 4 and activity score = 0 (no activity) set to Z-score = 0. Z-scores > 4 were considered activity score = 100, and Z-scores < 0 were considered activity score = 0.

Protocol: Tox21 Assay Protocol Summary:

The ERR cells were dispensed at 2,000 cells/5 ul/well in 1536-well white plates using a Multidrop dispenser. After the assay plates were incubated at a 37 C/5% CO2 incubator for 6 hours, 23 nL of compounds dissolved in DMSO, positive and negative controls or DMSO only was transferred to the assay plate by a pin tool. The plates were incubated at 37 C for 17.5 hours. 1 ul/well of CellTiter-Fluor reagent was added into the assay plates using a Flying Reagent Dispenser. After 30 min incubation at 37 C/5% CO2, the fluorescence intensity in the plates was measured using a ViewLux plate reader.
