Bactenecin vs PGLa

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

Bactenecin
Antimicrobial Peptide

Bactenecins are a diverse family of antimicrobial peptides from bovine neutrophil granules. The family includes both the small cyclic dodecapeptide Bac1 (with one disulfide bond) and the larger linear proline-rich Bac5 and Bac7....

PGLa
Antimicrobial Peptide

PGLa is a 22-residue alpha-helical antimicrobial peptide co-isolated with magainin-2 from the skin of the African clawed frog Xenopus laevis. Individually, PGLa and magainin-2 show modest antimicrobial activity, but when combined at equimolar ratios, they exhibit synergistic kill...
