Temporin A
Based on 1 Customer Validation
Temporin A is a short alpha-helical antimicrobial peptide isolated from the skin of the frog Rana temporaria. Temporin A is effective against a broad spectrum of Gram-positive bacteria. Temporin A interacts directly with the cell membrane of the microorganism and it is non-toxic to erythrocytes at concentrations that are antimicrobial. Temporin A also has antifungal activities (against yeast-like Candida albicans).

Biological Activity
Temporin A (TA) is a small, basic, highly hydrophobic, antimicrobial peptide amide (FLPLIGRVLSGIL-NH2) found in the skin of the European red frog, Rana temporaria. It has variable antibiotic activities against a broad spectrum of microorganisms, including clinically important Methicillin-sensitive and -resistant Staphylococcus aureus as well as Vancomycin-resistant Enterococcus faecium strains[2].
