Custom Antigens for today’s unmet needs & tomorrow’s innovation
Antigen and Protein Purification Experts
Logical Antigen specialises in the customised development of high-quality antigens and biologicals for research and manufacturing of diagnostic products. Antigens are a key component in the manufacture of in vitro diagnostic (IVD) test reagents, often used in controls to confirm test performance. However, unmet needs currently exist in relation to protein derived material availability, suitability and consistent performance. We aim to drive scientific and clinical innovation through agile and client-focused antigen manufacturing.
Our team of experts have decades of experience in protein purification and are ready to discuss customised options.

Precision- engineered antigens, developed for your diagnostic success
Leveraging advanced biotechnology platforms tailored to complex biological requirements and the highest standards of quality, we can design, develop, and produce customised antigens tailored specifically to the needs of IVD manufacturers.
A tailored approach ensures antigens retain their functional and immunological relevance to achieve maximum performance in your applications. Starting with the end in mind, Logical Antigen focusses on quality controlled, reliable processes that deliver long term supply sustainability at large scale.


Our Capabilities
Our capabilities are based on refined extraction, isolation, and purification techniques from native biological sources, to preserve structural conformation, post-translational modifications, and biological activity. The expert team also offers recombinant antigen development services to support diverse project requirements and achieve superior performance through novel downstream purification protocols.
