RAP tag: A new protein purification approach

A research team from the University of Tsukuba described a new approach for protein labelling and purification using plant cells. Using the RAP tag and PMab-2 antibody, this affinity purification approach showed high affinity and specificity. Moreover, they showed that plant-produced monoclonal antibodies maintain their characteristics and their production can optimized to reduce the cost of antibody-based approaches.
