ProA™ Trust

Alkali-tolerant rProtein A Resin
ProATM Trust is an alkali-tolerant Protein A affinity resin showing the high binding capacity
without significant activity loss after incubation with NaOH.
The ligand is derived from the IgG-binding domains of the Staphylococcus aureus Protein A.
It was engineered in order to provide higher binding capacity and alkali-tolerance than wild type Protein A1.
ProATM Trust is optimized to perform the cleaning-in-place (CIP) procedures.​
