Cardiotoxin Analog (CTX) IV (6-12)

Cardiotoxin Analog (CTX) IV (6-12) is a membrane active peptide that specifically targets negatively charged phospholipid membranes (such as phosphatidylserine and phosphatidylinositol) and can be isolated from the venom of the Taiwan cobra. Cardiotoxin Analog (CTX) IV (6-12) is a snake venom cardiotoxin that binds to cell membranes and embeds into lipid bilayers through hydrophobic interactions and electrostatic attraction, thereby destroying the stability of membrane structure. Cardiotoxin Analog (CTX) IV (6-12) can induce membrane lipid disorder and cell lysis, exhibiting hemolysis and cytotoxicity[1][2].
