Cascade ultrafiltration systems—Integrated processes for purification and concentration of lysozyme

This paper demonstrates the feasibility of using cascade ultrafiltration systems run at constant flux for efficient purification of lysozyme from chicken egg white. Integration of high-resolution purification with concentration is a key requirement in the purification of lysozyme, which is present at very low purity and concentration in egg white. A three-stage cascade ultrafiltration system, which focused on purification alone, gave a …
