MICROSPHERES CONTAINING CONDENSED POLYANIONIC BIOACTIVE AGENTS AND METHODS FOR THEIR PRODUCTION |
摘要 |
The present invention relates to novel compositions comprising microspheres and/or nanospheres containing condensed polyanionic bioactive agents, such as DNA. The polyanionic bioactive agent in the microspheres and/or nanospheres is preferably condensed using a polycationic condensing agent, such as poly-L-lysine. The present invention further relates to methods for producing the microspheres and/or nanospheres containing condensed polyanionic bioactive agents.
