Description: The Strep-tag II is an eight-residue minimal peptide sequence that exhibits intrinsic affinity toward streptavidin and can be fused to recombinant proteins in various fashions. The Strep-tag II exhibits affinity for streptavidin even when it is placed amidst a polypeptide sequence.The original Strep-tag had to be fused to the C-terminus of the recombinant protein in order to maintain a free peptide carboxylate group, giving rise to a salt bridge with an Arg side chain of streptavidin.To also allow for application at the N-terminus of the protein to be purified or even when inserted amid the polypeptide chain, the modified Strep-tag II (sequence: NWSHPQFEK) was subsequently engineered.
