FAQ
What are neutralizing antibodies (NAbs)?
Neutralizing antibodies are antibodies that bind to a viral vector and block its ability to enter target cells and deliver its genetic payload. In AAV gene therapy, NAbs can reduce or completely prevent successful transduction.
Why is NAb testing important in AAV gene therapy?
NAb testing helps identify patients with pre-existing immunity and evaluate immune responses following treatment. Understanding NAb levels is critical because neutralizing antibodies can impact the safety and efficacy of AAV-based therapies.
How do cell-based AAV NAb assays work?
Cell-based NAb assays measure the ability of antibodies in a sample to inhibit AAV-mediated transduction. By quantifying the reduction in biological activity, researchers can determine the presence and level of neutralizing antibodies.
Why use a cell-based assay for NAb detection?
Cell-based assays provide a functional assessment of neutralizing activity rather than simply measuring antibody binding. This makes them particularly valuable for understanding the biological impact of anti-AAV immune responses.
What makes Svar's NAb assays different?
Svar's cell-based assays are designed to provide biologically relevant measurements of neutralizing activity, enabling researchers to evaluate the functional effect of anti-AAV antibodies on vector performance.
Can Svar develop customized NAb assay solutions?
Yes. Svar Life Science can support customized assay development to meet specific gene therapy and vector assessment requirements.
