CL4H6(CAT: I024872) is a Ph-sensitive cationic lipid. CL4H6 is a major component of lipid nanoparticles (LNPs) that can be used to target and deliver siRNA and induce effective gene-silencing responses. In vitro studies, CL4H6 was found to effectively target hepatocyte and endosomal escapes, safely and efficiently delivering myocardial associated transcription factor/serum response factor (MRTF/SRF) -B siRNA into human conjunctiva fibroblasts.
