In vitro removal of beta-2-microglobulin from uremic blood with an immunoadsorption wall.

Dialysis-related amyloidosis (DRA), caused by the accumulation of beta-2-microglobulin (β-2M), remains a major concern in long-term renal replacement therapies. For years, we have developed an immunoadsorption wall (iWall) for the removal of β-2M. In this study, we employed a new approach taking advantage of the melting of a buffer ice rod to improve the conditions associated with the manufacturing of an iWall and tested its performance with uremic serum and blood.
