Triton <scp>CG</scp> ‐110 as an alternative for cell lysis in manufacturing of <scp>adeno‐associated virus</scp> ‐based gene therapy

Triton X-100 is one of the most widely used detergents for cell lysis in gene therapy product manufacturing. However, due to the aquatic toxicity of the degradation product, Triton X-100 is regulated by the European Chemical Agency as a substance of very high concern. In this study, we aim to identify eco-friendly detergent alternatives to replace Triton X-100. Tween 20, Tween 80, n-Dodecyl-β-D-maltoside (DDM), and Triton CG-110 were tested and compared with Triton X-100. Triton CG-110 demonstrated similar performance during the harvest and subsequent purification process for multiple AAV vectors at different scales. Therefore, Triton CG-110 represents an effective and environmentally safe detergent alternative to Triton X-100.
