Novel Uses of a Saponin and Method for Its Isolation

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to the identification and use of special saponins with acetyl residues from the plant Gypsophila elegans M. Bieb., specifically for enhancing the delivery (transfection) of nucleic acids, lipids, peptides, or proteins into cells. These saponins significantly increase transfection efficiency, performing even better than existing standards like Lipofectamin. The patent also describes a new method to isolate these saponins from plant roots.

Use CasesContent extracted from patent full text and abstract with AI.

• Improving gene therapy by increasing the efficiency of DNA/RNA delivery into human or animal cells.
• Enhancing the delivery of therapeutic nucleic acids, peptides, or proteins in research or clinical settings, such as cancer therapy or regenerative medicine.
• Boosting the performance of commercial transfection reagents in laboratory and industrial biotechnology applications.
• Facilitating the production of genetically modified cells or organisms for biomedical and agricultural applications.
• Advancing research in functional genomics and cell biology by improving lab transfection protocols.

BenefitsContent extracted from patent full text and abstract with AI.

• Transfection efficiency is much higher than with previous saponins or leading commercial reagents like Lipofectamin.
• Applicable both in vitro (lab settings) and in vivo (live animals or humans), broadening its utility.
• Low toxicity at active concentrations, making it safe for sensitive biological applications.
• Can be used alongside existing transfection reagents as a performance booster, making it compatible with current lab workflows.
• The isolation method allows scalable extraction of promising saponins from a renewable plant source.

Patent Abstract

The present invention relates to the novel use of saponins comprising 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.
