To enhance biopharmaceutical manufacturing efficiency and reduce costs, particularly for the purification of large biomolecules such as monoclonal antibodies (mAbs) and viral vaccines, Pinshan Biotech has developed the next-generation PolyExion Extra series of high-performance ion exchange chromatography resins. These products utilize microfluidic chip technology for precise microsphere fabrication, featuring a polystyrene/divinylbenzene (PS-DVB) matrix with exceptional mechanical strength, chemical stability, uniform particle size, and open super-porous structure. Through surface hydrophilic modification to minimize non-specific adsorption and unique surface functionalization technology, the resins deliver advantages including high flow rate, high resolution, high binding capacity, and low backpressure.
