  • METHOD FOR PRODUCING RECOMBINANT HYALURONIDASE
    Publication number: 20250136964
    Abstract: Disclosed is a method for producing hyaluronidase or a variant thereof. Specifically, the method is capable of changing the N-glycan levels under culture conditions including a controlled concentration of glucose in the culture medium and a decreased culture temperature for a specific culture time period, thereby increasing the specific activity by 10% or more and improving the quality and production yield.
    Type: Application
    Filed: November 7, 2024
    Publication date: May 1, 2025
    Applicant: ALTEOGEN Inc.
    Inventors: Soon Jae PARK, Kyuwan KIM, Sang Hoon YUN, Jeong Soo CHO, Kibum PARK, Minsoo BYUN, Hyung-Nam SONG, Ji-Sun KIM, Ki Seok NAM
