Streptavidin is a tetrameric protein purified from Streptomyces avidinii. It has wide use in numerous molecular biological protocols dues to its strong affinity for biotin. NWSHPQFEK (Strep II tag) is a nine amino acid peptide with high specificity and affinity towards streptavidin.GenScript THE™ NWSHPQFEK Tag Antibody [Biotin], mAb, Mouse is THE™ NWSHPQFEK Tag Antibody (A01732) conjugated with biotin. The conjugated antibody is suitable for detecting the expression level of NWSHPQFEK (Strep II tag) tagged fusion proteins.

Target Information

The Strep-tag II is an eight-residue minimal peptide sequence (Trp-Ser-His-Pro-Gln-Phe-Glu-Lys) that exhibits intrinsic affinity toward streptavidin and can be fused to recombinant proteins in various fashions. The original Strep-tag was a nine amino acid peptide with high specificity and affinity towards streptavidin which allows the simple purification of protein by use of affinity columns, but required addition to only the C-terminus of recombinant proteins. To also allow a Strep-tag to be placed at the N-terminus of recombinant proteins, it was re-engineered and re-named Strep-tag II.
