Commercially available antibodies often contain substances (e.g. BSA, glycine, tris, azide) that interfere in labeling reactions with enzymes or fluorophores.

The AbSelect™ Purification Kit quickly removes these contaminants of antibody labelling. It can also be used to purify antibodies from crude samples such as ascites fluid or immune serum.

The antibody to be purified or cleaned up ideally is in a volume of 100ul to 0.5ml. Up to 500µg of antibody can be purified in each run. The AbSelect method involves capture of the antibody on protein A resin and the removal of unwanted substances by a simple wash procedure. The purified antibody product is then eluted and neutralized.

The components of the AbSelect kit are fully compatible with the Lightning-Link™ conjugation system (available separately), which allows the purified antibody to be rapidly labeled with the signal of your choice!
