RGEN Repligen Corp

Repligen Corporation (NASDAQ:RGEN), a life sciences company focused on bioprocessing technology leadership, today announced the commercial launch of its CTech™ SoloVPE® PLUS System, the most advanced UV-based Variable Pathlength Technology system now available to biopharmaceutical manufacturers. The SoloVPE PLUS System is engineered to offer unparalleled accuracy, speed, and ease-of-use for at-line ultraviolet-visible (UV-Vis) concentration measurement in complex biological production workflows, from process development scale through cGMP manufacturing.

As the bioprocess industry shifts toward higher drug concentration formulations to improve efficiency and reduce production costs, there has been a growing need for faster, more reliable and more accurate analytical tools. The SoloVPE PLUS System addresses this need, utilizing variable pathlength spectroscopy to deliver precise concentration measurements in under 30 seconds, without the need for dilution or background correction.

This innovative technology is a significant addition to Repligen’s process analytics portfolio, advancing the company’s at-line capabilities and complementing both its in-line, real-time FlowVPX® System and fully integrated RPM™ (Real-time Process Management) TFF Systems. Applications for the SoloVPE PLUS System include measurement of protein concentration (such as for antibody-based drugs, including ADC drug-to-antibody ratio), quantitation of nucleic acids (DNA/RNA) and measurement of mRNA in mRNA-based therapeutics.

Olivier Loeillot, President and Chief Executive Officer at Repligen said, “The next-generation SoloVPE PLUS System is a success for our development team, delivering on the goal to achieve a new level of speed, precision and reproducibility. It’s an exciting advance for Repligen - and just the first of many new product launches we have planned for 2025.”

Kola Otitoju, Senior Vice President and Global Head of Process Analytics, said, “Repligen is at the forefront of PAT innovation, and the new SoloVPE PLUS System showcases our ability to evolve our bioprocessing technologies to meet our customers’ needs. The SoloVPE PLUS System delivers on the key performance factors required to support faster decision-making and greater efficiency, helping our customers improve both their productivity and bottom line."

The SoloVPE PLUS System offers several key advantages over current UV-Vis spectroscopy offerings in the market:

• Streamlined Workflow. Reduces process steps by 70%, from a seven-step process to just two - measure and report.
• Accelerated Acquisition Speed. Doubles the speed of data collection, delivering results in half the time compared to the legacy SoloVPE System.
• Enhanced Sensitivity and Reproducibility. Measures the widest range of concentrations without dilution—mAbs from 0.01 mg/mL to 320 mg/mL, with an R²≥ 0.999.
• Minimized Error-Prone Steps. Direct measurement of samples eliminates the need for dilution or additional sample preparation.
• Optimized Data Management. The CTech™ ViPER® ANLYTX Software integrates SQL for data storage and retrieval, and OPC-UA for standardized communication, enabling a streamlined, agile, and connected system that supports real-time access and scalable bioprocessing operations.
