WMicroTracker – 24/7 Automated Data Collection

The WMicroTracker provides the capability to measure the locomotor activity of nematodes including C. elegans and parasitic worms, cultured in multi-well plates. You can get detailed measurements of motion and viability, including path tracking, distance and speed measurements.

This system is also designed for high-throughput screening assays (Figure 1) to evaluate the biological effects of potential compounds/drugs, RNAi/morpholino, as well as for mutant phenotyping studies in small animals

With the WMicroTracker's 24/7 automated data collection capability, you can:

  • Automatically track and quantify worm movement (Figure 1).
  • Load your experiment, set your parameters and walk away. Your data will be ready for you at the end of the programmed time.
  • Perform live worm assays for several weeks at a time with high reproducibility of data.

Figure 1. The WMicrotracker ONE gives you data comparable to a thrashing assay, only 10 times faster. The WMicrotracker ONE quantifies the locomotor activity of a worm population in a 96 well plate with 30-70 animals per well. Data acquisition and analysis are automated and simultaneous. All activity is normalized to N2 controls.

WMicroTracker Toxicity Assay

Figure 2. Toxicity assay. The dose-response effect of oxidative stress on C. elegans locomotor activity over time can be observed. Worms were exposed to a reactive oxygen species (ROS) generating compound. Each concentration was tested four times, using 30-70 animals per well in a 96-well plate.

Figure 3. Lifespan assay. The decreased lifespan of skn-1 mutants can be observed. Samples were recorded for 1 hour once per day, four times per condition.

WMicroTracker Chemotaxis Assay

Figure 4. Chemotaxis Assay. Worm chemotaxis toward benzaldehyde was automatically recorded. Three concentrations of benzaldehyde were placed on an agar substrate in a multiwell plate, using 30-70 animals per well.
