Adeno-associated virus (AAV) is a widely used viral vector for the delivery of genetic material in gene therapy. Vector development and production at an industrial scale requires an efficient method for accurate quantification of viral capsids. Unfortunately, traditional techniques such as ELISA, HPLC, and ddPCR are time consuming and labor-intensive. This podcast introduces a rapid, label-free method for the direct capture and quantitation of various AAV serotypes using the Octet® Bio-Layer Interferometry (BLI) platform with Octet® AAVX Biosensors. These biosensors deliver results in as little as 15 minutes and can be used to quantitate AAV capsids in both crude and purified samples.
