Poster Session
Real-Time Monitoring of AAV Empty: Full Capsid Separations using Near Infrared High-Precision Tunable Laser Spectroscopy
Date/Time: Wednesday, May 14, 2025, 5:30pm – 7:00pm CT
Location: Poster Hall I2
Adeno-associated virus (AAV) vectors are a cornerstone of gene therapy, but their efficacy and safety depend heavily on the ratio of empty-to-full capsids. Traditional analytical methods for monitoring this critical quality attribute (CQA) during purification processes, such as ultracentrifugation and mass photometry, can be time-intensive and laborious, while rapid methods such as AEX-HPLC and SEC-MALS can typically not resolve partial from full capsids. Here, we present a novel approach utilizing Near Infrared (NIR) High-Precision Tunable Laser Spectroscopy (HPTLS) for real-time monitoring of AAV empty-to-full capsid ratios using chromatography. Nirrin Technologies’ proprietary HPTLS technology enables high-resolution spectral separation of capsid species, providing quantification of full and empty capsids in real-time. This method eliminates the need for extensive sample preparation while maintaining accuracy comparable to traditional methods. The integration of HPTLS into downstream bioprocessing workflows enhances process control, enabling rapid decision-making and reducing production timelines. This work demonstrates the potential of HPTLS to transform AAV purification through non-invasive, real-time analytics.
Real-time Monitoring of AAV
Atlas enables real-time insights on buffer quantitation, high-concentration proteins and AAV’s delivering improved process control, faster process development and advanced manufacturing.
The Atlas™
Replace Assumptions With Real Data.It’s Time.
Atlas reveals issues before they become big problems, providing rapid, on-demand, at-line analysis throughout the bioprocess. Only 15 µL of sample gets you data for excipients, surfactants, high-concentration proteins and monoclonal antibodies simultaneously in 1 minute. This is data which previously would’ve taken weeks. With Atlas, it’s all about you. Run your samples at line and get answers right when you need them. No sample prep, no complex analysis, just data you can trust.
