Determining the exact cause/effect relationship between a treatment and a cellular outcome is not a simple matter, but is critical for really understanding how therapeutic treatments affect target cells or exercise any off-target effects.

  1. Dosage (usually addressed by a dilution series)
  2. Exposure time
  3. Mechanism of Action
  4. Cell Type

In a recent Promega Webinar, A Cytotoxicity Assay That Fits Your Timeline, Promega scientist Dr. Andrew Niles presented the CellTox™ Green Cytotoxicity Assay—a new tool that gives researchers more power to answer the question “Is my compound or treatment toxic?” Continue reading “The 64 billion dollar question: Is my compound or treatment toxic?”
