Latest Patents

Shirahama holds a patent for a "Protein highly producing recombinant animal cell, method for preparing the same, and method for mass-producing protein using the same." This patent describes a method where a gene encoding a production amount-potentiating factor is introduced into an animal cell to transform it. Alternatively, both a protein production gene and the gene encoding the production amount-potentiating factor can be introduced into the animal cell. The production amount-potentiating factor used in this method has caspase activity inhibiting activity and/or protein biosynthesis activity potentiating action, such as baculovirus P35. The animal cell is cultured under conditions that prevent apoptosis, allowing for the mass production of the desired protein.
