Load the sample into the NucleoCassette, using the built-in piston to aspirate a pre-defined volume of approximately 50 μL. Place the NucleoCassette into the NucleoCounter and press "Run". In about 30 seconds, the total cell count will be calculated and shown on a built-in display.
RESULTS AND DISCUSSION
Using optional NucleoView software connected to your PC, you may additionally store and export results, as well as view an image of the stained cells. Results may be plotted as Optical Density (OD600) against Cell concentration (cells/mL) or Dry Cellular Weight (g/L) against Cell concentration (cells/mL).
Figure 2: NucleoCounter YC-100 raw image of yeast cells in suspension ( Saccharomyces cerevisiae ) after Reagent YC-100 treatment using 100-fold dilution. Cell count is approx. 8 x 107/mL. The objects have similar fluorescence intensities and are uniform in size, indicating minimal cell disruption. The yeast cells are uniformly dispersed throughout the entire image. The yeast cells may be manually monitored in the NucleoCassette measurement chamber using fluorescence microscopy with appropriate filters for propidium iodide.
Clean up is simple. After use, the NucleoCassette can be disposed of as biological waste, with the PI dye safely enclosed. Unlike flow systems and hemacytometers, the system requires no cleaning, maintenance, or calibration. For in-lab demo, contact New Brunswick Scientific.
