Defensin vs Tachyplesin

Defensin vs Tachyplesin — 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...

Tachyplesin
Antimicrobial Peptide

Tachyplesin I is an 18-residue disulfide-bridged beta-hairpin AMP from the hemocytes of the Japanese horseshoe crab (Tachypleus tridentatus). It exhibits potent antimicrobial, antiviral, and antitumor activity....
