  • Dewaxing buffer containing a water-soluble organic solvent and methods of use thereof
    Patent number: 8753836
    Abstract: Dewaxing buffers containing a water-soluble organic solvent, methods for use thereof, and kits incorporating dewaxing buffers. The dewaxing buffers contain a water soluble organic solvent that has a boiling point of at least 80° C. The dewaxing buffers described herein can be used to quickly and efficiently remove embedding paraffin from slide-mounted tissue sections in an aqueous buffer solution at elevated temperature without fear of paraffin redeposition of the slides. In addition, the dewaxing buffers described herein can be used to perform dewaxing and HIER in a single step, which can substantially reduce protocol time and lower the risk of sample loss or damage.
    Type: Grant
