Buforin II vs Tachyplesin

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

Buforin II
Antimicrobial Peptide

Buforin II is a 21-residue antimicrobial peptide derived from histone H2A in the stomach of the Asian toad Bufo gargarizans. Unlike most AMPs that kill bacteria by membrane disruption, Buforin II translocates across bacterial membranes without causing lysis and kills by binding n...
