Phylloseptin vs Plectasin

Phylloseptin vs Plectasin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Phylloseptin
Antimicrobial Peptide

Phylloseptins are a family of short, C-terminally amidated alpha-helical antimicrobial peptides isolated from the skin secretions of South American Phyllomedusa frogs. Unlike the related dermaseptins from the same genus, phylloseptins are shorter (19 residues) and show a distinct...

Plectasin
Antimicrobial Peptide

Plectasin is a 40-residue defensin-like antimicrobial peptide discovered in 2005 from the saprophytic fungus Pseudoplectania nigrella. It was the first AMP isolated from a fungal organism....
