Patents by Inventor Alexander Vlassov

Alexander Vlassov has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20210190809
    Abstract: Purifying target biomolecules, such as nucleic acids or proteins, from a biological source is a time intensive process and is typically performed by a skilled technician or scientist owing to the highly technical nature of the work. Systems, devices, and methods disclosed herein enable the automated bioprocessing and purification of target biomolecules from a biological source. For example, an instrument and disposable cartridge are provided for automatedly isolating and purifying nucleic acids (such as plasmid DNA from a bacterial culture) or for isolating protein from any biological sample. Such an exemplary instrument and cartridge can work in concert to timely release, mix, and move the target biomolecule and various reagents and buffers through a target biomolecule purification process, resulting in a purified target biomolecule with less manual oversight than traditional approaches.

  • Patent number: 10900038
    Abstract: Modification formats having modified nucleotides are provided for siRNA. Short interfering RNA having modification formats and modified nucleotides provided herein reduce off-target effects in RNA interference of endogenous genes. Further modification formatted siRNAs are demonstrated to be stabilized to nuclease-rich environments. Unexpectedly, increasing or maintaining strand bias, while necessary to maintain potency for endogenous RNA interference, is not sufficient for reducing off-target effects in cell biology assays.
