  • Uses of a saponin and method for its isolation
    Patent number: 11708388
    Abstract: The present invention relates to the novel use of saponins having acetyl residues on one of their sugar residues. These saponins are able to enhance the transfection efficiency to a surprisingly much higher extent than already known saponins and even than Lipofectamin.
    Type: Grant
    Filed: July 10, 2018
    Date of Patent: July 25, 2023
