Description	Biochem/physiol Actions	Product #
Cecropin A ≥97% (HPLC), powder	Antibacterial peptide originally identified in moths (Hyalophora cecropia) and later in pig intestine.	C6830
Cecropin B ≥97% (HPLC), powder	Antibacterial peptide originally identified in moths (Hyalophora cecropia) and later in pig intestine.	C1796
Cecropin P1 Porcine ≥95% (HPLC), powder	Antibacterial peptide originally identified in moths (Hyalophora cecropia) and later in pig intestine.	C7927
Defensin HNP-1 human ≥80% (HPLC)	This is an endogenous antibiotic peptide and monocyte chemotactic peptide produced by human neutrophils. Defensins are a family of 3-4 kDa (29-34 amino acids) peptides found in the granules of mammalian phagocytes. The members of this family are variably arginine-rich and share six conserved cysteine residues that participate in intramolecular disulfide bonds.	D2043
Defensin HNP-2 human ≥95% (HPLC)	This is an endogenous antibiotic peptide and monocyte chemotactic peptide produced by human neutrophils. Defensins are a family of 3-4 kDa (29-34 amino acids) peptides found in the granules of mammalian phagocytes. The members of this famuly are variably arginine-rich and all share 6 conserved cysteine residues that participate in intramolecular disulfide bonds.	D6790
Magainin I ≥97% (HPLC)	Antibiotic peptide. Thought to preferentially bind to anionic phospholipids abundant in bacterial membranes with the formation of dynamic peptide-lipid supramolecular pore and cell permeabilization, magainins are positively charged and amphiphatic. Binding to artificial neutral membranes has also been demonstrated.	M7152
Magainin II ≥97% (HPLC)	Antibiotic peptide. Magainins are positively charged and amphiphatic. Thought to preferentially bind to anionic phospholipids abundant in bacterial membranes with the formation of dynamic peptide-lipid supramolecular pore and cell permeabilization. Binding to artificial neutral membranes has also been demonstrated.	M7402
[Ala^8,13,18]-Magainin II amide ≥97% (HPLC)	Magainin analog with greater anti-microbial activity.	M8155
