Application

Polyadenylic acid-Polyuridylic acid (polyAU) is a double stranded homodimer studied for potential therapeutic activity, especially when coupled with radiotherapy. PolyA/U is used in comparative physiochemical studies with other duplex and single-stranded polymers such as poly-A and poly-U.
