Targeting and intestinal-absorption controlled liposome having sugar chain and therapeutic drug for cancer and diagnostic drug containing the liposome

摘要

An object of the present invention is to provide a liposome having a sugar chain bonded thereto, the sugar chain having an activity of specifically binding to various lectins (sugar chain recognizing proteins) present on the cell surfaces of various tissues and thus being capable of actually distinguishing a cell and a tissue in vivo, thereby efficiently delivering a medicinal drug or a gene.
