1. Preparation of HKGreen-4I working solution 1.1 Preparation of stock solution: Dilute 1 mg of HKGreen-4I with 150 μL of anhydrous DMSO to prepare a 10 mM stock solution. It is advised to aliquot and store HKGreen-4I storage solution at -20°C or -80°C in the dark. 1.2 Creating a functional solution Use preheated serum-free cell culture medium or PBS dilution stock solution to prepare a 1-10 μM HKGreen-4I working solution. Note: Please prepare the HKGreen-4I working fluid for usage by adjusting its concentration to suit the current circumstances. 2. Cell staining (suspension cells) 2.1 Centrifuge the cells, add PBS, and wash twice for five minutes each time. The density of cells is 1×106/mL. 2.2 Add 1 mL of the HKGreen-4I working solution, then let it sit at room temperature for a duration of 5 to 30 minutes. 2.3 Centrifuge for 3–4 minutes at 400 g, then remove the supernatant. 2.4 After adding PBS, wash the cells twice for five minutes each. 2.5 Re-suspend the cells in 1 milliliter of PBS or serum-free media, and use a flow cytometer or fluorescence microscope to observe. 3. Staining adherent cells in cells 3.1 Use sterile coverslips to cultivate adherent cells. 3.2 Aspirate extra culture medium after removing the coverslip from the medium. 3.3 Cover the cells fully with 100 μL of the dye working solution, shake gently, and allow incubate for five to thirty minutes. 3.4 Use a flow cytometer or fluorescence microscope to observe after aspirating the dye working solution and washing it twice in culture media for a total of five minutes each time.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 6 mg/mL (9.00 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 60.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 3 mg/mL (4.50 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 30.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: ≥ 1.75 mg/mL (2.63 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
