WIPO Patent Application WO/2023/138668
Kind Code:
A1
Abstract:
The present invention relates to a stable macromolecular type I recombinant collagen and a use thereof. The macromolecular type I recombinant collagen of the present invention is formed by performing multiple repetitions by using a short amino acid sequence derived from natural human type I collagen as a repeating unit, the short amino acid sequence being GAPGAPGSQGAPGLQ, and the number of repetitions being 75-110 times. The macromolecular type I recombinant collagen of the present invention has extremely good stability in an aqueous solution and can be stored in an aqueous solution for a long period of time.
