Latest Patents

HyunJoo Lee's latest patents include a method for selecting a high expression recombinant cell line. This invention relates to a method of selecting high producer clones by utilizing an expression vector. The expression vector comprises a gene expression cassette with a selectable marker gene linked to polyA and another gene expression cassette encoding a recombinant protein of interest. This innovative method allows for the selection of high producer clones from cell populations at least 10 times fewer than existing methods. It also enables the use of a lower concentration of MTX compared to conventional gene amplification strategies, thereby shortening the development period of cell lines and reducing labor and costs.

Another notable patent is for a human host cell designed for producing recombinant proteins with high quality and quantity. This invention involves a human host cell generated from the fusion of a human embryonic kidney-derived cell and a human B-cell-derived cell through genetic engineering techniques. The stable characteristics of this human host cell make it an efficient tool for producing heterologous desired recombinant protein-based pharmaceuticals.
