Protein A Chromstar® FF is an affinity chromatography medium for antibody purification, which separates through the specific interaction between antigen and antibody. This chromatography medium is used for the purification of monoclonal and polyclonal antibodies.
Protein A Chromstar® FF offers a variety of options. It is easy to scale up and has high throughput performance advantages:
Recombinant protein A is produced in E. coli and engineered with directional conjugation to enhance binding capacity: Epoxy-based conjugation ensures low ligand shedding. Recombinant protein A has similar specificity for the IgG Fc region as native protein A, allowing for increased selection and yield.
The process scale-up of this affinity chromatography resin is simple and easy to operate.
