Latest Patents
Junker holds a patent for the "Isolation of purified TGF-β1 and TGF-β2 from bone tissue." This patent describes a method for purifying bone-derived TGF-β proteins through a series of processes, including anion exchange, cation exchange, and reverse phase HPLC. The method also includes optional filtration and Heparin-Sepharose processes. The filtration process is designed to select proteins with a molecular weight between approximately 10 kilodaltons and 100 kilodaltons. The anion exchange process utilizes a strongly cationic resin with quaternary amine functional groups, while the cation exchange process employs a strongly anionic resin with sulfonic acid functional groups. The TGF-β proteins can be eluted from the reverse phase HPLC column using an acetonitrile solution combined with aqueous trifluoracetic acid. This purification process yields highly enriched TGF-β1 and TGF-β2 proteins.
