The enzyme Hyaluronidase catalyses the degradation of hyaluronic acid (hyaluronan), a major component of the extracellular matrix. In medicine hyaluronidase is used in combination with other drugs to lower the viscosity of hyaluronic acid, to increase the tissue permeability, to speed drugs dispersion and delivery. In cosmetic medicine it’s also used to dissolve hyaluronic acid dermal fillers. As market demand continues to rise there is an increasing need for manufacturing processes that are not only efficient but also robust and compatible with current Good Manufacturing Practice (GMP) standards. This need is especially critical when proteins are expressed in complex biological systems.

In this study, we present our developments in ligand discovery aimed at the targeted purification of Hyaluronidase. Using Navigo Pure’s proprietary Precision X® ligand libraries, we identified a set of affinity ligands tailored for the selective capture of this enzyme. The ligands were evaluated in the context of CHO supernatant and were characterized in terms of their binding affinity, target specificity and overall capture performance.

Our findings demonstrate that the selected ligands effectively enrich the target molecule while minimizing non-specific interactions, establishing a foundation for streamlined purification workflows. The underlying ligand platform Precision X® developed by Navigo Pure is designed to extend the advantages of Protein A affinity chromatography, traditionally applied to antibody purification, to the broader space of non-antibody biologics. Through our Precision Capturing® technology, we offer a novel and proprietary approach that enables simplified process architectures while maintaining high standards for yield and purity. This platform is particularly wellsuited for the purification of targets, where conventional methods often fall short in scalability, reproducibility, or regulatory compliance.

By enabling a more predictable and scalable purification strategy, Precision Capturing® provides a powerful tool for bioprocess development teams aiming to meet the rigorous demands of clinical and commercial manufacturing. It offers not only a high degree of operational robustness but also flexibility in adapting to diverse expression systems and process scales. This positions our platform as a unique solution for next-generation biologics manufacturing, supporting the advancement of novel peptide-based therapeutics from research through to GMP-compliant production.

The ongoing clinical success of incretin-based peptide therapeutics, particularly glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonists, has firmly established their therapeutic relevance in the treatment of type 2 diabetes and obesity. These peptides have demonstrated superior efficacy in improving glycemic control and promoting weight loss and remain the only class of drugs approved for both indications. Their dual effectiveness, coupled with favorable safety profiles, has intensified pharmaceutical and biotechnological interest in their large-scale production and commercialization. As market demand continues to rise, there is an increasing need for manufacturing processes that are not only efficient but also robust and compatible with current Good Manufacturing Practice (GMP) standards. This need is especially critical when peptide drug precursors are expressed in complex biological systems such as E. coli or yeast.

In this study, we present our initial developments in ligand discovery aimed at the targeted purification of two clinically validated incretin mimetics: Tirzepatide, a dual GIP/GLP-1 receptor agonist, and Semaglutide, a potent GLP-1 receptor agonist. Using Navigo Pure’s proprietary Protein A-derived ligand libraries, we identified a set of affinity ligands tailored for the selective capture of these therapeutic peptides. These ligands were evaluated in the context of clarified E. coli lysates, and were characterized in terms of their binding affinity, target specificity, and overall capture performance.

Ferritin is a critical protein complex essential for iron storage and release in living organisms. Ensuring high purity and effective isolation of Ferritin is vital for its various biomedical and industrial applications. However, due to its low presence in human plasma, the purification of Ferritin can be very challenging.

The small amount of Ferritin (13-400 ng/mL) present in plasma makes purification a significant challenge for purification techniques. However, we have successfully overcome this challenge. Our next-gen Affinity Chromatography (AC) methods enable the isolation and purification of Ferritin with exceptional precision, ensuring high purity and yield even from very small initial amounts. This achievement underscores our commitment to leveraging cutting-edge technology to solve complex biochemical problems.

The development of AC for Ferritin purification is a significant bioprocessing advancement. This technique improves the efficiency of Ferritin isolation and ensures the production of high-quality Ferritin for applications in medical diagnostics and therapy. It can serve as a blueprint for many other antibodies, non-antibodies and proteins with clinical potential facing purification obstacles.

The custom affinity resin was developed using the Precision Capturing® technology. The platform brings the benefits of Protein A affinity chromatography to the space of non-antibody proteins. Precision Capturing® enables a simpler process architecture resulting in optimized purity and yield. It is a unique and innovative affinity technology for DSP development to achieve a robust, predictable, scalable, and GMP-compliant purification procedure.
