AAV Vector Gene Therapy Testing for Cell and Gene Therapy
Digital PCR for Viral Vector Development, Characterization, and Quantitation
Cell and gene therapies are utilized to treat genetic diseases by introducing genetic material into the patient in order to alter cell function. These therapies can be delivered in vivo using viral vectors modeled on adenoviruses, adeno-associated viruses, or retroviruses, with the goal of either replacing, editing, adding to, or silencing the targeted gene.
The production of sufficient quantities of viral vectors is important in affecting gene transfer. In this step, characterization and quantification become key in viral vector manufacturing for therapies.
Digital PCR is becoming an indispensable tool in the analysis of viral vectors for cell and gene therapy applications. The absolute quantification afforded by digital PCR – as opposed to the relative quantification using qPCR – provides researchers with the ability to precisely quantify and characterize viral vectors.
From sample extraction to analysis for viral vectors
The Nio+ system offers a fast, easy-to-use platform for quantification of genetic targets. In order to detect and quantify multiple genetic targets in a single run, the Nio+ system also offers the highest multiplexing available on the market today. When coupled with a sample preparation platform such as the Maxwell® RSC instruments from Promega, users are provided with a seamless end-to-end workflow – from sample preparation to analysis.
