The Chromatography resins are key materials in biopharmaceutical production and research laboratories for purifying and separating biomolecules such as proteins, antibodies, and nucleic acids. These resins function as the stationary phase in chromatography systems, enabling selective binding of target molecules while contaminants are washed away. Common resin types include ion exchange resins, which separate molecules based on charge; affinity resins, which target specific molecular interactions; and size-exclusion resins, which separate molecules based on size. Chromatography resins are essential in the manufacturing of high-purity therapeutics, vaccines, and diagnostic reagents. They are designed for high chemical stability, mechanical strength, and long service life, ensuring reproducible and reliable results over multiple purification cycles. Advances in chromatography resin technology have enhanced separation efficiency, scalability, and selectivity, making them vital tools in modern biotechnology and pharmaceutical production. Their versatility and performance make chromatography resins indispensable for laboratory, research, and industrial applications.
