Apidaecin vs Plectasin

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

Apidaecin
Antimicrobial Peptide

Apidaecins are proline-rich antimicrobial peptides from the hemolymph of honeybees (Apis mellifera). Unlike membrane-disrupting AMPs, apidaecins kill bacteria exclusively through intracellular ribosome targeting after transporter-mediated uptake, similar to Bac7 and PR-39....

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....
