PN5

Product Description

PN5 is a novel antimicrobial peptide originally isolated from pine needles of Pinus densiflora. This 11-amino-acid peptide displays an α-helical amphipathic structure with broad-spectrum antimicrobial activity against both Gram-positive and Gram-negative bacteria. Research investigations have examined PN5 in studies of bacterial membrane permeabilization mechanisms, LPS neutralization pathways, NF-κB and MAPK signaling modulation, and anti-inflammatory responses in septic models.

The peptide maintains stability in the presence of proteolytic enzymes and does not induce bacterial resistance development in serial passage studies. PN5 is used in controlled laboratory environments for investigating antimicrobial peptide mechanisms of action, bacterial cell membrane interactions, immunomodulatory pathways, and alternative approaches to antibiotic resistance research.

Supplied as pharmaceutical-grade lyophilized powder with third-party verified purity testing for qualified research institutions conducting in vitro research applications only.
