AAV purity and VP ratio determination by CE-SDS
AAV capsid protein purity and VP ratio are critical quality attributes in viral vector development. Their reliable measurement is key to ensuring batch consistency, supporting comparability studies and strengthening CMC strategies.
In this application note, we present an optimised CE-SDS method with laser-induced fluorescence (LIF) detection, developed to enhance sensitivity, peak resolution and quantitative robustness under GxP conditions.

Key highlights of the method
- LOQ established at 8 × 10⁹ vg/mL
- Clear separation of VP species
- Detection of low-level impurities (~5%)
- 0.7% RSD across two instruments and two days
- Sample stability confirmed after 19h at 10°C
Why it matters for your AAV programme?
Robust VP ratio determination supports:
- Confident batch-to-batch comparison
- Clear data interpretation during process optimisation
- Stronger comparability assessments
- Reliable CMC documentation
Reliable VP ratio assessment is essential for robust CMC and AAV development strategies.
Strengthen your AAV analytical strategy with a high‑performance CE‑SDS approach designed for robust viral vector characterisation.
