HPPH is a second-generation photosensitizer, which acts as a photodynamic therapy (PDT) agent. 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 show a stronger fluorescence signal than those treated with free HPPH. The fluorescence of HPPH is rather weak[1].
Tumors are treated with an immune-enhancing PDT regimen followed by a tumor-controlling PDT regimen can lead to enhancement of anti-tumor immunity, while retaining effective control of primary tumor growth. To test this hypothesis, a combination treatment regimen is devised in which Colo26-HA tumor-bearing BALB/c mice are treated with an HPPH-PDT regimen known to lead to enhanced anti-tumor immunity (0.4 μmoles/kg HPPH followed 18 h later by illumination with 665 nm light for a total dose of 48 J/cm2). Following illumination, mice are rested for 9 days; on the ninth day, mice are injected with HPPH. On day 10 following the first treatment, tumors are treated with a tumor control treatment regimen (illumination with 665 nm light for a total dose of 132 J/cm2 given)[2].

Cell experiment: |
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]. |

Animal experiment: |
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]. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
