Lucifer Yellow CH dipotassium is a high-intensity fluorescent probe containing free hydrazyl groups. Lucifer Yellow CH can react with fatty aldehydes at room temperature. Lucifer Yellow CH serves as a biological tracer to monitor neuronal branching, regeneration, gap junction detection and characterization, and selective ablation of cells after aldehyde fixation. Lucifer yellow CH displays the maximum excitation/emission of 430 nm/540 nm, respectively.

Preparation of Lucifer Yellow CH (dipotassium) working solution
1 Preparation of the stock solution
Dissolve Lucifer Yellow CH (dipotassium) in DDH₂O to obtain 1 mg/mL of Lucifer Yellow CH (dipotassium).
Note: It is recommended to store the stock solution at -20°C -80°C away from light and avoid repetitive freeze-thaw cycles.
2. Preparation of Lucifer Yellow CH (dipotassium) working solution.
Dilute the stock solution in serum-free cell culture medium or PBS to obtain 0.5% of Lucifer Yellow CH (dipotassium) working solution.
Note: Please adjust the concentration of Lucifer Yellow CH (dipotassium) working solution according to the actual situation.

Cell staining
1. Cell preparation:
For suspension cells: Centrifuge at 1000 g at 4°C for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time.
For adherent cells: Discard the cell culture medium, and add trypsin to dissociate cells to make a single-cell suspension. Centrifuge at 1000 g at 4°C for 3-5 minutes and then discard the supernatant. Wash twice with PBS, 5 minutes each time.
2. Add 1 mL of Lucifer Yellow CH (dipotassium) working solution, and then incubate at room temperature for 5-30 minutes.
3. Centrifuge at 400 g at 4°C for 3-4 minutes and then discard the supernatant.
4. Wash twice with PBS, 5 minutes each time.
5. Resuspend cells with serum-free cell culture medium or PBS, and then detect by fluorescence microscope or flow cytometer.

Precautions
1. It is recommended to store the stock solution at -20℃ or -80℃ away from light and avoid repetitive freeze-thaw cycles.
2. Please adjust the concentration of Lucifer Yellow CH (dipotassium) working solution according to the actual situation.
3. This product is for R&D use only, not for drug, household, or other uses.
4. For your safety and health, please wear a lab coat and disposable gloves to operate.
