Overview

Viral vector-based gene therapies are large drug product formulations comprised of protein and nucleic acid components containing over 200,000 atoms. Waters liquid chromatography (LC) combined with optical detection (UV, MALS) and mass spectrometry (MS) provide the analytical means to accurately characterize and quantify these heterogeneous structures and their attributes, at both component and intact levels. Routine measurements include viral titer, aggregate/impurities analysis, viral protein ratios, peptide mapping & modification analysis, encapsidation efficiency, and genome integrity.


Applications

Waters provides precision engineered SEC, HILIC, and IEX columns tailored for AAV and adenovirus applications, and robust HPLC/UHPLC/UPLC systems that can highly resolve viral vector components. Larger capsids especially susceptible to shear are separated more gently using field-flow fractionation (FFF).

AAV capsids are made of three viral proteins that self-assemble in a 1:1:10 ratio. Post-translational modifications (PTMs) can impact product performance. Workflows for PTM & impurities analysis support capsid engineering, process development and release testing.

Size exclusion chromatography with multiangle light scattering (SEC-MALS) and UV detection enables measurement of multiple AAV attributes, including titer, size-distribution, molar mass, aggregate, and empty/full ratio. Asymmetric field flow fractionation with MALS (FFF-MALS) allows for measurement of larger capsids.

Genome integrity testing ensures the viral vector genome contains only the intended genetic sequence and is free from mutations or rearrangements. Alkaline gel electrophoresis has historically been used but lacks resolution. Higher-resolution LC methods are highly desired for accurate measurement.

a) Overlayed mass spectrum of AAV8 zoomed into to the 2.5–6 MDa mass range with 100 % empty, and full capsid treated with 30-minute incubations at 4, 22, 35, and 50 °C. b) Charge spectrum of AAV8 zoomed into the 2.5–6 MDa mass range with 100 % empty, and full capsid treated with 30-minute incubations at 4, 22, 35 and 50 °C.
Full (blue) and empty (red) titers determined by RT-MALS during elution (34 – 48 minutes) and strip (> 48 minutes) in the final linear gradient. Buffer ionic strength is represented by the dashed black line.
Zoomed views of an AAV2 chromatogram as obtained with stainless- steel hardware (4.6 x 150 mm, 5 µm particle, red trace) versus hHPS hardware (XBridge Premier GTx BEH SEC 450 Å 2.5 µm 4.6 x 150 mm Column, black trace). Separations were performed with a mobile phase containing a standard ionic strength buffer (10 mM phosphate pH 7.4 + 200 mM KCl).
Relative quantification of VP proteins was measured by optical detection, including (A) UV and (B) Fluorescence (FLR). Peak annotation shows the assignment and calculated relative abundance of the detected components. With FLR detection, the S/N of VP3 is almost five times higher than the S/N of using UV detection with a 10-fold higher mass load, suggesting an approximately 50-fold improvement in sensitivity.
