Cecropin vs Kalata B1

Cecropin vs Kalata B1 — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Cecropin
Antimicrobial Peptide

Cecropins are a family of antimicrobial peptides first discovered in 1980 by Hans Boman in the silkmoth Hyalophora cecropia. Cecropin A was the first AMP characterized from an insect, establishing the paradigm of innate immune peptide-based defense....

Kalata B1
Antimicrobial Peptide

Kalata B1 is the prototype cyclotide - a cyclic peptide with a head-to-tail backbone cyclization and three disulfide bonds forming a cystine knot topology. Isolated from the plant Oldenlandia affinis, which is traditionally used in Africa to accelerate childbirth (uterotonic use)...
