A natural polysaccharides schizophyllan (SPG) can form a stoichiometric complex with polynucleotides. The complexed polynucleotide shows better anti-nuclease resistance than naked ones, indicating that the complex can be used as an olig-DNA carrier, especially to transport antisense DNA to intracellular mRNAs. In the present work, we attached β-cyclodextrin (βCyD) to SPG and a galactose moiety was connected to the βCyD by use of adamantine vs. βCyD interaction. The attached galactose increased the cellular ingestion when the complex was administeted to Hep G2, owing to the presence of asialoglycoprotein receptor on the cellular surface.
