Abstract
The safety of biopharmaceutical products is a critical research topic in the pharmaceutical field, with viral contamination risk being particularly significant. Given the complex origins of raw materials and the diversity of production processes for biologics, ensuring the absence of potential viral residues has become a core challenge for the industry. This study aims to establish a comprehensive and efficient viral safety testing strategy to address viral contamination issues in biopharmaceutical products. By integrating multiple modern analytical techniques, including nucleic acid amplification technology (PCR), reverse transc ription PCR (RT-PCR), and protein-based immunological methods, a multi-tiered viral screening system was constructed. Additionally, next-generation sequencing (NGS) technology was introduced, which substantially enhanced the ability to detect unknown viruses. The results demonstrate that this testing strategy can effectively identify both known and potentially unknown viruses, exhibiting high sensitivity and specificity in practical applications. Furthermore, validation experiments conducted on typical biologics further confirm the applicability and reliability of this strategy in complex matrices. A major innovation of this study lies in the combination of traditional detection methods with cutting-edge molecular biology technologies, resulting in a broader coverage and more efficient viral safety evaluation system. This provides crucial technical support for quality control in the biopharmaceutical industry and lays the foundation for the development of future relevant standards.
