Safety Data Sheet



Use this Dye Reagent Concentrate to refill the Bio-Rad Protein Assay, a simple, accurate method for total protein measurement. This colorimetric assay based on the Bradford method is compatible with many common lab reagents.

Flexible assay formats:

  • Use the standard assay for protein concentrations between 200 and 1,400 µg/ml (20–140 µg total protein)
  • Use the low-concentration assay for protein concentrations < 25 µg/ml (1–20 µg total protein)
  • Use 96-well microplates for rapid assays
