AT A GLANCE
Protocol summary
- Prepare Prolite™ Orange working solution (50 µL)
- Add BSA standards and/or test samples (50 µL)
- Incubate at room temperature for 30 minutes
- Read fluorescence intensity at Ex/Em = 485/590 nm
Important notes
Thaw all the kit components at room temperature before starting the experiment.
PREPARATION OF STOCK SOLUTION
Protein Enhancer stock solution (500X):
Add 100 µL of Protein Enhancer Buffer (Component E) into the vial of Protein Enhancer (Component C). Note: 20 µL of Protein Enhancer stock solution (500X) is enough for make 10 mL working solution. Unused Protein Enhancer stock solution (500X) should be stored in single use aliquots at -20 oC.
PREPARATION OF STANDARD SOLUTION
For convenience, use the Serial Dilution Planner: https://www.aatbio.com/tools/serial-dilution/11105
Note: Standards and test samples should be prepared in Protein Enhancer working solution.
PREPARATION OF WORKING SOLUTION
1. Protein Enhancer working solution:
Add 20 µL of Protein Enhancer stock solution (500X) into 10 mL of Assay Buffer (Component D) and mix them well.
2. Prolite™ Orange Working Solution:
Add 10 µL of Prolite™ Orange (Component A) into 5 mL of Assay Buffer (Component D) and mix them well. Note: 5 mL of Prolite™ Orange working solution is enough for 1 plate. Prepare enough Prolite™ Orange working solution fresh for each experiment.

Protein assay
- Add 50 µL of BSA standard, blank control, and test samples (See table 1 and 2) into a solid black 96-well plate. Note: For a 384-well plate, add 20 µL of samples.
- Add 50 µL/well of Prolite™ Orange working solution into BSA standard, blank control, and test samples to make the total assay volume of 100 µL/well. Note: For a 384-well plate, add 20 µL of Prolite™ Orange working solution into each well.
- Incubate the reaction for 10 to 30 minutes at 37 oC, protected from light.
- Monitor the the fluorescence increase with a fluorescence plate reader at Ex/Em = 485/590 nm.
