  • Publication number: 20240336936
    Abstract: The present disclosure relates to methods for producing lentiviral vector-producing cells. Specifically the methods utilize two plasmids, rather than four, to provide the required packaging elements and transfer vector to a cell, allowing for the production of a large number of lentiviral producer cells, including suspension-based cells, and the production of high amounts of lentivirus. These methods allow for the production of cells that can be later induced to produce lentivirus, and can be tailored to include a specific gene of interest.

  • Publication number: 20240210385
    Abstract: A method of characterizing a lentivirus, comprising: providing a sample comprising a lentivirus population comprising a fully loaded lentivirus, a partially loaded lentivirus, and/or an empty lentivirus; contacting a substrate with the sample to capture the lentivirus population; contacting the captured lentivirus population with a first fluorescent agent comprising a first fluorescent label and a first binding molecule that binds an envelope protein of the lentivirus, a second fluorescent agent comprising a second fluorescent label and a second binding molecule that binds a capsid protein of the lentivirus, and a third fluorescent agent comprising a third fluorescent label that binds a payload; illuminating the captured lentivirus population with light to excite the fluorescent agents; detecting fluorescent lights emitted from the fluorescent agents at different wavelengths; and characterizing the lentivirus according to the detected fluorescent lights.
