We developed a new cationic lipid suitable for use as a DNA carrier in the presence of 10% sera. The novel compound (abbreviated as Arg-Chol) contains cholesterol and a dipeptide consisting of glycine and sterically protected arginine. The efficiency of reporter gene transfection using liposomes based on this new reagent was compared with that of liposomes made with other cationic derivatives of cholesterol. Lipoplexes formulated with the newly synthesized lipid mediate in vitro transfection of B16(F10) murine melanoma cells in the presence of 10% sera more efficiently than in other cell lines and compared with other cholesterol derivatives studied.

Созданы новые упаковочные клетки F18/pJD, содержащие вирус-помощник на базе трансформационно-дефектного мутанта адаптированного к уткам варианта пражского штамма вируса саркомы Рауса (td daPr-RSV-C), которые продуцируют репликативно-дефектньш ретровирусный вектор с титром IO 6 КОЕ/мл. Делетирование цис-активкых последовательностей-ψ упаковочной области и обращенных повторов Е, фланкирующих src, каптированного варианта ретровируса при создании конструкции вируса-помощника позволило получить пул векторного вируса, свободный от последовательностей вируса-помощникаι
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
