Lipopeptide CPE4 (TFA)

Lipopeptide CPE4 TFA is a PEG-modified peptide E4 [ (EIAALEK) 4]. Lipopeptide CPE4 TFA is capable of coiled-coil formation when attached to liposomes. Lipopeptide CPE4 TFA triggers membrane fusion between liposomes and living cells with concomitant efficient cytosolic delivery of a variety of compounds such as fluorescent dyes Propidium Iodide (PI) and TO-PRO-3 iodide (HY-117070), and Doxorubicin (DOX) (HY-15142A). Lipopeptide CPE4 TFA can be used for drug delivery research[1].
