A fast and easy one-step purification strategy for plant-made antibodies using Protein A magnetic beads

Abstract

A major difficulty to reach commercial- scale production for plant-made antibodies is the complexity and cost of their purification from plant extracts. Here, using Protein A magnetic beads, two monoclonal antibodies are purified in a one-step procedure directly from non-clarified crude plant extracts. This technique provides significant savings in terms of resources, operation time, and equipment.
