Amsphere A3 is a new protein A resin to be used in the downstream purification process of therapeutic antibody drug manufacturing.
JSR has developed Amsphere A3 by combining its proprietary polymer technology - polymer particles with hydrophilic surface chemistry, large surface area, and optimized porosity - and recombinant protein biotechnology.
Amsphere A3 is characterized by high dynamic binding capacity, alkaline resistance, high flow rate adaptability, sharp elution profile, high impurity removal, and easy packing.
Lots of biotech/pharmaceutical companies and CDMOs all over the world have already been using Amsphere A3 to manufacture antibody drugs using large scale columns.
JSR is willing to provide technical services to help optimize the process.
