HepatoFluor™: An In Vitro Fluorescence Assay for Hepatocyte Viability and Function


  • Determine viability of hepatocyte cultures.
  • Measure hepatocyte life span in culture.
  • Study hepatocyte stem cells.
  • Determine hepatocyte mitochondrial dysfunction.
  • Study liver cell interactions.
  • Determine the response of hepatocytes to different agents.
  • Incorporates a non-destructive, highly accurate alamarBlue™ fluorescence reagent.
  • Uses a fluorescence plate reader or multimode plate reader with an excitation filter at 560nm and an emission filter at 590nm.
  • Non-subjective, instrument-based and quantitative readout procedure.
  • Easily multiplexes with other fluorescent labels/markers.
  • Combine with gene expression assays etc or other endpoints for more information from a single sample.
  • Flexibility to use the investigators own growth medium and protocols.
  • High throughput capability.
  • Results in 1-3 hours after adding reagent.
  • Simple, time efficient and cost effective.

Principle of Using STEMFluor to Measure Cell Proliferation using a Fluorescence Resazurin Readout

HepatoFluor™ can be used for multiple species and different sources of hepatocytes (e.g. fresh, cryopreserved, male, female, mixed and hepatocyte cell lines such as HepG2).

  • Incorporates the measurement of non-fluorescent Resazurin (alamarBlue™) to fluorescent Resorufin in an oxidation/reduction reaction that occurs only in live cells. The amount of fluorescence (relative fluorescence units, RFU) is dependent on the metabolic status of the cells and therefore is not only a measure of metabolic viability, but cell proliferation or inhibition.
  • After culture, add 10μL of reagent, mix and measure signal between 30 minutes and 4 hours in a fluorescence plate reader.
  • Uses a plate fluorometer or multi mode plate reader to measure fluorescence with an excitation filter 560nm and an emission filter of 590nm.

For Research Use Only. Not for clinical diagnostic use.
Fluorescence or multimode plate reader with a 560nm excitation and 590nm emission filter.

  • AlamarBlue™/Resazurin Reagent
  • 3% SDS solution to stop the reaction.
  • Resorufin to standardize the assay.
  • Non-sterile, black, 96-well plates for assay standardization.
  • Sterile, black, 96-well plates, for hepatocyte culture.
  • Sterile, adhesive foil covers to maintain sterility of unused wells.
PLEASE NOTE. The investigator has the flexibility to culture hepatocytes using their own hepatocyte growth and/or maintenance medium. However, HepatoGro™ medium can be purchased separately from Preferred Cell Systems™.
