  • Silk gland recombinant expression vector of silkworm () expressing human epidermal growth factor, preparation method and use thereof
    Patent number: 12509712
    Abstract: Disclosed is a silk gland recombinant expression vector of silkworm expressing human epidermal growth factor, a preparation method and use thereof. The recombinant expression vector is formed by fusing truncated silk fibroin light chain N-terminal domain, C-terminal domain, optimized human epidermal growth factor and silkworm nuclear polyhedrosis virus enhancer, and removes the redundant part of the extra domain of endogenous silk protein contained in the fusion protein to the maximum extent.
    Type: Grant
