Clavanin vs Human Neutrophil Peptide 1

Clavanin vs Human Neutrophil Peptide 1 — 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....

Human Neutrophil Peptide 1
Antimicrobial Peptide

Human Neutrophil Peptide 1 (HNP-1) is the most abundant alpha-defensin in human neutrophil granules, where it constitutes up to 30% of total protein content. Alpha-defensins HNP-1, -2, -3, and -4 are the human versions of the ancestral defensin family....
