  • Method for producing fibroin-like protein
    Patent number: 11117937
    Abstract: A method for producing a fibroin-like protein is provided. A fibroin-like protein is produced by a method of culturing Escherichia coli having a gene encoding the fibroin-like protein in a medium, inducing expression of the gene encoding the fibroin-like protein, and collecting the fibroin-like protein, wherein accumulation of an organic acid at the time of inducing the expression is reduced, and wherein the gene is expressed under control of a tryptophan promoter.
    Type: Grant
    Filed: May 25, 2018
    Date of Patent: September 14, 2021
    Assignees: AJINOMOTO CO., INC., SPIBER INC.
    Inventors: Kentaro Nakase, Yoshinori Takashima, Takeshi Nagahiko
  • Fibroin-Like Protein Production Method

  • Fibroin-Like Protein Variant and Cell Culture Method
    Publication number: 20190016763
    Abstract: A technique for efficiently culturing cells such as stem cells is provided. Cells such as stem cells are cultured using a cell culture vessel coated with a fibroin-like protein into which a cell adhesion sequence containing RGD (Arg-Gly-Asp) is inserted.
