In vitro preparation of amelogenin nanoparticles carrying nucleic acids.
Amelogenin, a matrix protein involved in biomineralization of enamel, can self-assemble to form nanospheres in a pH-dependent manner. Nucleic acids (single-stranded, double-stranded, and plasmid DNA, as well as RNA) could be co-precipitated with amelogenin, demonstrating a strong binding of nucleic acids to amelogenin. The amounts of co-precipitated nucleic acids were analyzed and binding levels u
