Online Activation.

Unlike batch activation, online activation with STYROS™ Activated Affinity Simulated Monolith™ columns is more controllable and more reproducible.
Minute amounts of rare proteins can be immobilized on the proper size column while monitoring the process through a detector.
The immobilization time is reduced from days to hours.
The proteins are less likely to become denatured as a result of long shaking and mechanical forces.

Once immobilized, the protein becomes more stable if kept under proper conditions.

Many immobilization procedures, both on line and in batch have been described in details in the published literature.

These columns are offered in many sizes both in PEEK and Stainless Steel.
