生物活性

Protegrin-1 is an orally active antibacterial peptide. Protegrin-1 activates ERK, COX2, NFκB, inhibits Apoptosis, and NO production. Protegrin-1 has antibacterial activity against S. aureus, E. faecium, E. coli, P. aeruginosa and K. Pneumoniae, with MBC values between 10 and 20 µM. Protegrin-1 has antiviral activity against dengue NS2B-NS3. Protegrin-1 has anti-inflammatory activity. Protegrin-1 is used in the study of inflammatory diseases and infections[1][2][3][4][5][6][7][8].

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.
