生物活性

Desferricoprogen is a hydrophobic fungal iron chelator siderophore. Desferricoprogen reduces atherosclerotic plaque formation and inhibits lipid peroxidation in aortic roots in ApoE−/− mice on an atherogenic diet. Desferricoprogen can lower the level of oxidized LDL (oxLDL) and inhibit oxLDL-induced HO-1, CD36, and TNF-α mRNA expression. Desferricoprogen inhibits TNF-α-induced endothelial cell activation, VCAM-1, ICAM-1 experssion and preserves endothelial monolayer integrity. Desferricoprogen can be used for the research of atherosclerosis[1][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.
