Pyropheophorbide-a (Standard)

Pyropheophorbide-a (Standard) is the analytical standard of Pyropheophorbide-a. This product is intended for research and analytical applications. Pyropheophorbide-a (Ppa) is a photosensitizer used in photodynamic therapy (PDT) for tumors. Pyropheophorbide-a exhibits phototoxic effects on tumor cells, such as cervical cancer cells, and also has anti-lipogenesis activity. Pyropheophorbide-a shows potential for research in the fields of cancer and age-related macular degeneration (AMD). Pyropheophorbide-a derivatives also demonstrate inhibitory activity against tumor cells.

For research use only. We do not sell to patients.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
