Beta-Defensin 2 vs Kalata B1

Beta-Defensin 2 vs Kalata B1 — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Beta-Defensin 2
Antimicrobial Peptide

Human beta-defensin 2 (HBD-2) is an inducible antimicrobial peptide expressed by skin keratinocytes, respiratory epithelium, and gut epithelium in response to microbial infection and pro-inflammatory cytokines. Unlike the constitutively expressed HBD-1, HBD-2 expression is strong...

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)...
