  • Compositions and methods for protein expression and delivery
    Patent number: 11510881
    Abstract: Methods and compositions that provide an environment that promotes enhanced protein expression and/or folding are provided. More particularly, engineered thermostable ferritin assemblies capable of encapsulating polypeptides, nucleic acids or small molecules, which includes a modified ferritin subunit which lacks an unstructured carboxy-terminal sequence are provided. Methods and compositions for delivery of protein therapeutics are also provided.

  • Light-Activated Two-Component Protein Binding Matrix
    Publication number: 20170349546
    Abstract: A binding pair for chromatographic separation or purification of a molecule of interest, where one binding member of the pair is an isomerizable organic molecule and the other binding member of the pair is an isomer-specific affinity agent bound to a molecule of interest. The binding pair associates and disassociates upon exposure to a binding agent, such as using light, decreased intensity of light, darkness, heat, stress, ions, an isomerizable affinity agent, change in pH, or a combination thereof.
