Purification of Disassembled Capsid Protein by Hydroxyapatite Chromatography Enhances Virus‐Like Particle Recovery

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Virus‐like particles (VLPs) are a promising modality with extensive applications in prophylactic and therapeutic vaccine design. Human Papillomavirus (HPV) vaccines are one such example where VLP vaccine applications have led to the successful reduction in HPV‐associated diseases, such as cervical cancer.

Nuclease‐Free Scalable Purification of Physalis Mottle Virus‐Like Particles Expressed in Escherichia coli

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Plant virus‐like particles (VLPs) are promising nanotechnology platforms, but their translation requires purification strategies suitable for large‐scale production. Here, we developed a nuclease‐free downstream process for Physalis mottle virus (PhMV) VLPs expressed in Escherichia coli, combining ammonium sulfate precipitation, low‐pH ...

Fluid‐induced slip on a rate‐and‐state fault during co‐ and post‐injection: The interplay of fluid pressure diffusion and poroelastic stress

Deep Underground Science and Engineering, EarlyView.
Fault slip can occur ahead of the injection pressure front due to poroelastic stress. Our model captures the interaction of pressure, stress, and friction, providing new insights into injection‐induced seismicity and post‐injection fault slip. Shut‐in operations can either mitigate or accelerate seismic events depending on fault conditions and ...
