Application

Trileucine (Leu-Leu-Leu), an endosome escape moiety, may be used for pH-dependent endosomal membrane disruption to release agents such as antisense oligonucleotides (AONs) inside cells. Trileucine is used to evaluate the absorption characteristics of reversed phase liquid chromatography (HPLC) media.

Pseudorevertants able to use L-leucyl-L-leucyl-L-leucine as a leucine source have been isolated from a Salmonella typhimurium strain carrying stable (nonreverting) mutations in pepN, pepA, and pepB. These strains carry mutations at a locus pto (peptidase T overproducer) tightly linked to
