The invention discloses an artificial
oil body carrier for the
targeted therapy of mastocarcinoma as well as a preparation method and an application thereof. With the preparation method, a pJO1-oleZH2
plasmid is converted to enter the host
cell of
escherichia coli BL21 (DE3), oleZH2 proteins are produced by induction, and oil and the oleZH2 proteins are mixed to prepare an artificial
oil body carrier. Invitro and invivo experiments confirm that the artificial
oil body carrier disclosed by the invention can be effectively applied to
target therapy, and the oil body carried covered with fluorescent substances can reflect HER2 / neu positive
cancer cells so as to specifically detect the mastocarcinoma
cell excessively expressing HER2 / neu. The artificial oil body carrier has the advantages of simple preparation process, extra small environmental
pollution, good stability in blood cells or serum, small volume and the like, is cheap and efficient, is convenient to operate and is easy to transport. The artificial oil body carrier can be used for covering anti-mastocarcinoma drugs of different types of oil
solubility, can effectively kill mastocarcinoma cells after being coated on drugs and can carry out
specific detection and
target therapy for mastocarcinoma cells.
