The CBP affinity tag （Calmodulin Binding Protein affinity tag） is a useful tool in protein research that is typically fused to the N- or C-terminus of a protein. The CBP affinity tag exhibits high specificity in binding to its cognate affinity partner, enabling targeted purification of the tagged protein. And it significantly improves the purification efficiency of proteins when used in tandem affinity purification techniques.
