Stearyl-(homoarginine)8 (trifluoroacetate salt)

Stearyl-(homoarginine)8 is a cell-penetrating peptide conjugated to stearic acid (Cay-10011298) that has been used in the generation of liposomes for plasmid DNA or siRNA delivery in vitro. Liposomes containing stearyl-(homoarginine)8 and in complex with plasmid DNA enter NIH3T3 cells via the endocytosis pathway. Liposomes containing a high density, but not a low density, of stearyl-(homoarginine)8 and encapsulating plasmid DNA increase plasmid DNA expression without being degraded by lysosomes in NIH3T3 cells. Stearyl-(homoarginine)8-containing liposomes encapsulating siRNA targeting the mRNA encoding GAPDH decrease GAPDH levels in primary human aortic smooth muscle cells. Solubility: Water: Slightly soluble: 0.1-1 mg/ml.
