  • WNT/SFRP COMPLEXES, WNT-CONTAINING COMPOSITIONS, WNT-EXPRESSING CELLS, AND METHODS OF MAKING, PURIFYING, AND USING SAME
    Publication number: 20210380649
    Abstract: This disclosure describes isolated protein complexes including a Wnt and a sFRP; compositions including a Wnt; a cell overexpressing a Wnt and a sFRP; compositions including a cell overexpressing a Wnt and a cell overexpressing a sFRP; methods of making the protein complexes, compositions, and cells; and methods of using the isolated protein complexes, compositions, and cells. This disclosure further describes methods of forming a complex including a Wnt and a sFRP and methods for isolating a Wnt. Also described herein are methods that may be used to purify a Wnt without the use of a detergent.

  • Recombinant sweet protein mabinlin
    Patent number: 6051758
    Abstract: Recombinant materials for the production of practical amounts of the sweet protein, mabinlin are provided. In addition, transgenic plants which have inherently sweetened edible parts result from modifying native plants containing edible parts to express the mabinlin gene. Single-chain forms of this protein which retain their sweetening property are also provided.
