Better Surface Chemistry for Better Separation MoreLess
Sepax Technologies, Inc. is a specialized company that operates in the biotechnology market, providing high-tech solutions for the separation and analysis of biomolecules. Their products are primarily used in the pharmaceutical and biotech industries, serving clients who require precise and reliable methods for analyzing complex biological substances.
The company's main offerings include Proteomix® HIC Butyl columns and Monomix™ MC SEC resins. The Proteomix® HIC Butyl columns are used for high-resolution hydrophobic interaction separation of biomolecules, such as monoclonal antibodies (mAb), Antibody Drug Conjugates (ADCs), and their fragments. Simply put, these columns help to separate complex biological substances based on their hydrophobicity, or their tendency to repel water.
The Monomix™ MC SEC resins, on the other hand, are used for size exclusion chromatography (SEC), a method used to separate biomolecules based on their size. These resins are particularly stable and versatile, with a broad pH tolerance range and compatibility with many commonly used solvents and buffers.
Sepax Technologies also offers a full chromatographic separation solution for ADCs, which includes a range of products for the analysis of ADCs aggregate, monomer, fragment, and free drug. This comprehensive solution allows for detailed analysis of ADCs, which are complex molecules used in targeted cancer therapies.
The company's business model is based on selling these high-tech products and solutions to clients in the biotech and pharmaceutical industries. They also offer technical support to their clients, ensuring that their products are used effectively and efficiently.
