In Vitro

Pheophorbide A (10 µM) increases lymphatic endothelial cells (LECs) sprouting, proliferation and tube formation[1].
Pheophorbide A-mediated photodynamic therapy (Pa-PDT) inhibits cellular growth on Hep3B, in a dose-dependent manner with an IC50 of 1.5 μM[2].
Pheophorbide A (2 µM, 24 h) induces apoptosis in Hep3B cells after photo-activation[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Pheophorbide A-mediated photodynamic therapy (Pa-PDT) (10 mg/kg (i.v.) or 30 mg/kg (i.p.)) significantly inhibits tumor growth in C3H mouse model with subcutaneous injection of AT-84 cells[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male immunocompetent C3H mouse (six-week-old, inoculated subcutaneously with AT-84 cells)[3]
Dosage: 10 mg/kg intravenous (i.v.) or a 30 mg/kg intraperitoneal (i.p.) injection
Administration: IV or IP; after 24 h, PDT was performed
Result: Pa-PDT, especially i.v. Pa-PDT, significantly inhibited tumor growth up to 70%, while the i.p. Pa-PDT-induced inhibition was up to 43.4% relative to the control group at the end of period.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
