Guide (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs).
Labeling of Protein:
1.The protein concentration was adjusted to 1 mg/mL for 100 μL.
2. A 100 μL aliquot of the protein solution was mixed with Cyanine3 maleimide tetrafluoroborate (8 μg) in DMSO.
3. Incubated overnight at 4°C in the dark.
4. Labeled proteins were desalted using a G25 desalting column to remove excessive Cyanine3 maleimide tetrafluoroborate.
5. Fluorescence intensities (FI) of labeled proteins were measured at excitation and emission wavelengths of 550 nm and 570 nm, respectively.
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. .
