Übersicht

AF647 NHS Ester is a far-red fluorescent dye with good photostability. Its fluorescence signal decays slowly during long-duration experiments and maintains stable fluorescence for extended periods, which is beneficial for long-term tracking and observation of biomolecules. It has a high fluorescence quantum yield. The activated ester group of this dye can react with amino groups (primarily primary amines) on target biomolecules to form stable amide bonds, thereby labeling biomacromolecules with AF647 fluorescent moieties.

Spectral properties: 

Excitation/absorption maximum: 651 nm 

Emission maximum: 671 nm 

Extinction coefficient (ε): 265000 

Fluorescence quantum yield (Φ): 0.33 

Precautions for Fluorescent Products: 

1. Activated esters are prone to hydrolysis. After taking out from the refrigerator, allow the vial to warm to room temperature in a dry environment before opening. Since the reagent quantity is small, gently tap the vial several times before opening to ensure all powder falls to the bottom.

2. It is recommended to prepare the stock solution fresh at first use. Use the dissolved reagent as soon as possible to guarantee experimental performance.

3. Fresh anhydrous DMSO is required for dissolution. Water contamination will cause hydrolysis of the activated ester and compromise experimental results.

4. The prepared stock solution is susceptible to hydrolysis upon exposure to water. If not fully consumed in one experiment, aliquot the solution (e.g., 5–8 μL per tube), seal with parafilm, wrap with aluminum foil, place in a well-sealed plastic bag containing desiccant, and store hermetically at ≤ -20°C protected from light.

5. It is recommended to optimize cell density, dye/probe concentration and incubation time in preliminary tests before formal experiments to determine optimal experimental conditions.
