Making the working solution of Lucifer Yellow CH (dilithium salt).
1. Preparation of stock solution To make a 1 mg/mL stock solution of Lucifer Yellow CH (dilithium salt), dissolve 1 mg of Lucifer Yellow CH (dilithium salt) in 1 mL of DDH2O. Note: After aliquots, the Lucifer Yellow CH (dilithium salt) storage solution should be kept in the dark at -20°C or -80°C. 2. Utilizing the pre-heated serum-free media or PBS, dilute the stock solution into 0.5–1% Lucifer Yellow CH (dilithium salt) working solution. Note: Before using, please make sure that the concentration of the Lucifer Yellow CH (dilithium salt) working solution is appropriate for the current circumstances. Staining of cells 1. Preparation of cells Suspension cells: Centrifuge cells to collect them, then add PBS and wash twice for five minutes each time. Adherent cells: Add islet digested cells after discarding the culture medium. Centrifuge, remove supernatant, add PBS, and wash twice for five minutes each time. 2. Add 1 mL of the working solution for 5–30 minutes (Lucifer Yellow CH, dilithium salt). 3. Discard the supernatant after centrifuging at 400 g for three to four minutes at 4°C. 4. To wash the cells twice, five times apiece, add PBS. 5. Re-suspend the cells in 1 milliliter of PBS or serum-free water, and observe using a flow cytometer or fluorescence microscope. Note: 1. After aliquoting, the Lucifer Yellow CH (dilithium salt) storage solution should be kept out of the light at -20°C or -80°C. Frequent freezing and thawing should be avoided. It can be kept for one month at -20°C and six months at -80°C. 2. You may adjust the Lucifer Yellow CH (dilithium salt) working solution concentration according to your specific needs. 3. This product should not be used for clinical diagnosis or treatment, nor should it be included into food or medication. It is intended only for research use. 4. Please wear disposable gloves and a lab coat for your health and safety. |

Contrasting observations exist which indicate that in plants the fluorescent dye lucifer yellow CH (LYCH) either can be used as a tracer for endocytosis or as a substrate for an anion transporter located at the vacuolar membrane. In addition, LYCH as a disulphonated substance may represent an analogue of sulphonated or sulfated natural compounds like some flavonoids. We performed uptake experiments with LYCH into isolated rye vacuoles and observed saturable (Km = 0.3-0.6 mM) vacuolar transport and accumulation of the dye against the concentration gradient only when MgATP was present. GTP and, to a low extent, UTP could substitute for ATP, while the non-hydrolysable ATP analogue AMP-PNP did not drive LYCH uptake. Vanadate and probenecid, the latter substance is known to inhibit organic anion transport at the liver canalicular membrane, both strongly decreased the vacuolar uptake of LYCH, while bafilomycin A1, a specific inhibitor of the vacuolar H+-ATPase, had no effect. Together with the fact that abolishment of the delta pH via CCCP had only a weak influence on LYCH accumulation, our results indicate that this compound is taken up into rye vacuoles by a directly energized process. Uptake of LYCH was strongly inhibited by other sulfated compounds including sulfobromophthalein and the flavones apigenin 7,4'-disulfate and luteolin 7,4'-disulfate arguing for the presence of a vacuolar transporter for structurally different sulphonated or sulfated compounds. Glucuronates like the rye-specific flavone luteolin 7-O-diglucuronide also strongly decreased uptake of the dye, whereas only a weak effect was observed in the presence of glutathione and a glutathione conjugate, suggesting that LYCH uptake is not mediated via the vacuolar glutathione conjugate pump.
