  • Publication number: 20260083883
    Abstract: Recombinant human type III collagen for promoting angiogenesis, and a preparation method and an application method thereof are provided, which relate to the field of genetic engineering technologies. The amino acid of the recombinant human type III collagen is as shown in SEQ ID NO: 1. The method replaces nine different sites of a full-length natural type III collagen with a GFOGER sequence from type I collagen specifically binding to integrin sites, thereby enhancing promote angiogenic function without changing a total length of natural full-length amino acids. Meanwhile, the method replaces four natural integrin sites with lower adhesion rates, thus the recombinant type III collagen have higher adhesion, to further promote angiogenesis. Through this modification method, the angiogenesis rate will be increased by more than 37%, and the molecular weight of protein translated by the recombinant human type III collagen is moderate, making it easy to prepare.

  • Patent number: 12451528
    Abstract: A method of in-situ electrolyte preparation in a flow battery includes providing a vanadium-based electrolyte solution having vanadium ions of predominantly vanadium V4+ to a first electrode and a second electrode of at least one cell of a flow battery. The vanadium V4+ at the first electrode is converted to vanadium V3+ and the vanadium V4+ at the second electrode is converted to vanadium V5+ by providing electrical energy to the electrodes. A reducing agent is then provided to the vanadium V5+ at the second electrode to reduce the V5+ to vanadium V4+. The vanadium V3+ at the first electrode is then converted to vanadium V2+ and the vanadium V4+ at the second electrode is then converted to vanadium V5+ by providing electrical energy to the electrodes. A simple method to produce predominantly vanadium V4+ electrolyte from a V5+ source, such as V2O5, is also taught.
