  • Labeled solid supports for organic synthesis
    Patent number: 8129517
    Abstract: The disclosed invention pertains to improved oligonucleotide manufacturing methods, including novel support compositions that are optionally labeled, their methods of preparation and use. The compositions and methods are particularly well suited for high throughput oligonucleotide manufacturing in that the automated support recognition facilitates loading of the wells with the proper supports. In addition, the labeled supports can be used to confirm that each well of a multi-well plate, such as a 96 or 384 well plate, was properly loaded.
