Latest Patents

Tada's latest patents include groundbreaking innovations such as an antibody-encoding recombinant DNA and its use. This invention involves transforming a bacterium of the genus Bacillus by introducing a vector that incorporates DNA encoding an antibody. The resulting transformant is cultivated in a medium to produce and accumulate the antibody in an active form in the culture liquid. This method allows for the easy production of recombinant antibodies in large amounts, thanks to successful secretory expression using Bacillus.

Another notable patent is related to recombinant human lymphotoxins that possess an N-terminal extended linker. This invention discloses a novel recombinant human lymphotoxin mutein that combines with an antibody at an inactive site of the LT molecule. It liberates the LT molecule easily from the antibody after incorporation into tumor cells. The recombinant human LT mutein is prepared by introducing a polydeoxyribonucleic acid containing a nucleotide sequence coding for a specific amino acid sequence into a replicable vector. This innovation is useful for tumor-selective carcinostatics and enhances the activity of LT while reducing its side effects.
