MabPolishTM DUO

>>Introduction >>Product Charactistics >>Ordering Info >>How to Order


MabPolish DUO is a class of novel resins with inert shell in the outer-layer of the bead (see the diagram below). The shell has size-exclusion effect that blocks molecules based on their molecular weights. Impurities smaller than a mAb can penetrate the shell and then be captured by the mixed-mode ligand inside the bead. It is a very gentle method with little loss of product.

The figure above shows the effectiveness of blocking IgG by the size-exclusion shell.

Key Features Application Guide
MabPolishTM DUO 150A
MabPolishTM DUO 400A
Shelled anion mixed-mode resin.

The shell of 150A can block molecules of 150 KDa.

The shell of 400A can block molecules around 400 KDa

Flow-through mode to capture impurities smaller than IgGs at a wide range of pH and conductivity.

MabPolish DUO 400 range can be run at faster flow velocity to remove high molecular weight species with low loss of target antibodies.
MabPolishTM DUO 150C
MabPolishTM DUO 400C
Shelled cation mixed-mode resin.

The shell of 150C can block molecules of 150 KDa.

The shell of 400C can block molecules around 400 KDa.

MabPolish DUO can be used in flow-through mode to remove impurities of less than 150 KDa from monoclonal antibodies or other antibody materials. Examples of the possible application scenario could be:
