Mart Toots, an accomplished inventor based in Össu, Estonia, has made significant contributions to the field of biotechnology. With a total of five patents to his name, he has been at the forefront of developing advanced methods for creating stable mammalian cell lines, driving innovation in this essential area of biological research.

Latest Patents

One of Toots' most recent patents, “Platform for Developing Stable Mammalian Cell Lines,” outlines a groundbreaking approach for generating parental cell lines suitable for targeted integration. This innovative method involves the introduction of binding sites for the BPV1 E2 protein to landing pad vectors, enabling precise localization of the vector to a transcriptionally active region within the genome. The process allows for the selection of cells with high expression levels of reporter genes, which can subsequently be utilized in the development of cell lines that express other recombinant proteins through recombination-mediated cassette exchange (RMCE). The landing pad constructs include crucial recombination target sites for site-specific recombinases, simplifying the replacement process with expression constructs that contain the same recombination target sites. This method results in the generation of producer cell lines with less effort compared to traditional methods that rely on random integration.
