Description

Phenidone, an orally active dual inhibitor of cyclooxygenase (COX) and lipoxygenase (LOX), ameliorates rat paralysis in experimental autoimmune encephalomyelitis. Phenidone is a potent hypotensive agent in the spontaneously hypertensive rat[1][2]. Phenidone is used as a photographic developer[3].

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.
