生物活性

Cercosporin is produced by a plant pathogen, Pseudocercosporella capsellae. Cercosporin is a potent photosensitizer with a short activation wavelength, mostly suitable for superficial photodynamic therapy (PDT) treatments, especially when it is necessary to avoid perforations[1]. Cercosporin contains the perylenequinone structural features necessary to PKC activity with an IC50 of 0.6-1.3 μM[2].

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.
