AbSelect™ Antibody Concentration and Clean-Up Kit

Antibodies are sometimes only available at low concentrations and often contain low molecular weight substances that interfere in labeling reactions with enzymes, biotin, streptavidin and fluorophores. The AbSelect™ Antibody Concentration and Clean-Up Kit can be used to:

1. Quickly and easily concentrate antibodies and proteins
2. Remove non-protein additives such as sodium azide, tris and glycine
3. Perform a simple buffer exchange for more favourable conjugation conditions

The AbSelect™ Antibody Concentration and Clean-Up Kit method utilizes a simple spin column to easily and quickly remove excess buffer from the antibody thereby providing a more concentrated antibody solution.

Benefits of the AbSelect Concentration and Clean-up kit:

• Easy and quick to use
• High recoveries, around 60-100%
• Suitable for Lightning-Link Ab labeling kits and for other kits

Kit Contents:

• 3 spin cartidges/collecting tube assemblies
• 1 bottle of AbSelect™ conjugation buffer

The antibody will be retained by the filter, while the buffer can be exchanged by centrifugation into a more suitable one.

Please note that if other proteins (e.g. BSA, Gelatin) are present, they will be retained by the filter as well and concentrated.
