Optimizing the particle and pore size of the Eshmuno® base matrix along with the immobilization of the Merck proprietary ligand enables a significant increase in dynamic binding capacity. Eshmuno® A resin shows higher dynamic binding capacity than other commercially available media. The sharp breakthrough curve allows for higher loading of Fc-containing protein to be purified, thereby maximizing column throughput.
