Modern biopharmaceutical technologies typically of decolorization resin use biological microbial fermentation processes, enzyme-catalyzed reactions, or biologically metabolites obtained by cell culture.

Bio-pharmaceuticals separation--Ion exchange and adsorption Resin & system
Ion learning exchange and adsorption method is a cost-efficient separation technique that has been widely used in the pharmaceutical industry. It is primarily a way to achieve separation and purification on a large scale with ion exchange systems with complex and designable ion exchange resins. It removes impurities, concentrates the target, and produces highly pure pharmaceuticals.
