Clavanin vs Theta-Defensin

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

Clavanin
Antimicrobial Peptide

Clavanin is a histidine-rich alpha-helical antimicrobial peptide originally isolated from the tunicate Styela clava. It is active at low pH, suggesting a role in intracellular killing of phagocytosed bacteria....

Theta-Defensin
Antimicrobial Peptide

Theta-defensins are the only known cyclic peptides produced in the animal kingdom. Found in rhesus macaques and other Old World primates, they are formed by ligation of two 9-residue alpha-defensin gene products into an 18-residue macrocyclic structure....
