The Pierce Coomassie Plus Assay Reagent is a single, ready-to-use solution for measuring protein concentration. Following a simple procedure, absorbance is measured at 595nm. The assay costs only pennies per sample and can be performed in either test tube or microplate format. The Pierce Coomassie Plus Assay Reagent provides increased linearity of response and only half the protein-to-protein variability of other commercial Bradford assay formulations.


Features:

  • Colorimetric—measure with a standard spectrophotometer or plate reader (595nm)
  • Easy to use—single reagent; no working reagent preparation required
  • Fast—almost immediate color development
  • Broad range—detects protein concentration in the range 1 to 1500 µg/mL
  • Better—improved linearity and response-uniformity compared to traditional Bradford formulations
  • Flexible—microplate and cuvette protocols provided
