Molecular weight
Fluorescamine is intrinsically non-fluorescent but reacts rapidly with primary aliphatic amines, including those in peptides and proteins, to yield a blue-green-fluorescent derivative. The Amplite® fluorescamine protein assay kit provides a simple method for quantifying protein concentration in solutions. This Amplite® fluorescamine protein assay kit can be performed in a convenient 96-well or 384-well microtiter-plate format and easily adapted to automation with no separation steps required. The assay can be completed within 30 minutes. With the Amplite® fluorescamine protein assay kit, as little as 3 ug/mL of BSA can be detected.

Example protocol


Protocol summary

  1. Prepare  fluorescamine working solution (25 µL)
  2. Add BSA standards or test samples (75 µL)
  3. Incubate at room temperature for 5 - 30 minutes
  4. Read fluorescence intensity at Ex/Em = 380/470 nm

Important notes
Thaw all the kit components at room temperature before starting the experiment.


BSA standard

For convenience, use the Serial Dilution Planner:

Dilute the appropriate amount of BSA Standard 1 mg/mL (Component C) into PBS by performing 1:2 serial dilutions to get serial dilutions of BSA standard (BS7 - BS1).


Add the whole content of DMSO (Component B) into the bottle of Fluorescamine (Component A), and mix well. Note: 2.5 mL of fluorescamine working solution is enough for 1 plate.

BL 75 uL PBS
TS 75 uL Test Sample
  1. Prepare BSA standards (BS), blank controls (BL), and test samples (TS) according to the layout provided in Tables 1 and 2. For a 384-well plate, use 30 µL of reagent per well instead of 75 µL.

  2. Add 25 µL of  fluorescamine working solution to each well of BSA standard, blank control, and test samples to make the total assay volume of 100 µL/well. For a 384-well plate, add 10 µL of fluorescamine working solution into each well instead, for a total volume of 40 µL/well.

  3. Incubate the reaction at room temperature for 5 to 30 minutes, protected from light.

  4. Monitor the fluorescence increase with a fluorescence plate reader at Ex/Em = 380/470 nm.
