Title of Abstract: Solid-Phase Purification of Synthetic DNA Sequences.

Description of Technology: Scientists at FDA have developed a high-throughput method for purifying full-length phosphorothioate and native DNA sequences. This method comprises a modified silica gel that enables capture of DNA sequences functionalized with a novel linker specifically designed for exclusive capture of full-length sequences. This Start Printed Page 19739technology has been shown to generate DNA sequences of high purity without the need of expensive equipment and associated accessories. This discovery may improve the availability of pure DNA sequences for clinical and/or synthetic biology applications.

Potential Commercial Applications:

  • A high-throughput purification technique for producing small and large quantities of highly pure DNA sequences.

Competitive Advantages:

  • Cost effective.
  • High-throughput capabilities.
  • Time saving.
  • High purity.

Development Stage:

  • In vitro data available.
