Data Sheet Material Safety Data Sheet (MSDS)

An anti-microbial peptide (AMP) of the cathelicidin family, originally discovered in pig neutrophils. Tritrpticin has potent and broad anti-microbial activity against Gram-positive and Gram-negative bacteria, some fungi, and protozoa.

Tritrpticin is thought to exist in a range of conformations in solution, and recognise its targets with high selectivity and efficiency whilst displaying low haemolytic activity. The peptides three sequential tryptophan residues flanked by two prolines and four arginines are important for the peptides interaction with membranes and for its mechanism of action. The presence of these three tryptophan and four arginines residues, also class Tritrpticin as a member of the Arg/Trp-rich family of AMPs.
