Defensin vs Temporin

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

Defensin
Antimicrobial Peptide

Defensins are a superfamily of small, cysteine-rich cationic antimicrobial peptides that form a critical component of innate immunity across virtually all multicellular organisms. In humans, alpha-defensins (HNP-1 to -4 in neutrophils; HD-5, HD-6 in intestinal Paneth cells) and b...

Temporin
Antimicrobial Peptide

Temporins are a family of short (10-14 amino acid) cationic antimicrobial peptides isolated from the skin secretions of the European common frog (Rana temporaria). First described by Simmaco et al....
