Fluorescence image of 4T1 cells incubated with 0.49 µg/mL GO-PEG, 1 μM HPPH (free HPPH) or equivalent amount of GO-PEG-HPPH (1 µM HPPH and 0.49 µg/mL GO-PEG) after 24 h. The cellular uptake of GO-PEG-HPPH and HPPH is investigated with 4T1 murine mammary cancer cells. The cells are incubated with GO-PEG-HPPH and free HPPH at equivalent HPPH concentration (1 µM) for 24 h and then observed with a confocal microscope. Cells treated with GO-PEG-HHPH shows stronger fluorescence signal than those treated with free HPPH. In fact, the fluorescence of HPPH is rather weak[1].

溶剤 & 溶解度
DMSO : 2 mg/mL (3.14 mM; ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (3.93 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (3.93 mM); Suspended solution
This protocol yields a suspended solution of ≥ 2.5 mg/mL (saturation unknown). Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

4T1 cells are cultured in 96-well cell culture plates at 1×104/well for 24 h and then treated with GO-PEG-HPPH, HPPH, or GO-PEG at a series of concentrations (0.078125, 0.15625, 0.3125, 0.625, 1.25, 2.5, 5, 10, and 20 μM). Then, 20 µL of MTT solution (5.0 mg/mL) is added to each well. After the 4 h incubation with the MTT, the media are removed and 100 µL of DMSO is added to solubilize the formazan crystals. The cell toxicity efficacy is measured with a microplate reader at an absorbance of 570 nm[1].

Mice[2]
Tumor-bearing mice are injected in the tail vein with 0.4 μmol/kg HPPH or 5 mg/kg Porfimer sodium (PII), followed 18-24 h later by illumination to a total light dose of 48 J/cm2 or 132 J/cm2 delivered at a light dose-rate of 14 mW/cm2. Control mice are treated with photosensitizer or light alone. Mice receiving a combination PDT regimen are treated initially with 0.4 μmol/kg HPPH or 5 mg/kg PII followed 18-24 h later by light dose of 48 J/cm2 given at 14 mW/cm2; 9 days later, mice are again injected with photosensitizer and tumors are illuminated with light at a dose of 132 J/cm2 given at 14 mW/cm2[2].
