Proteins 67(4): 1198-1202
A novel peptide was designed which possesses nanomolar affinity of less than 20 nM for streptavidin. Therefore it was termed Nano-tag and has been used as an affinity tag for recombinant proteins. The minimized version of the wild type Nano-tag is a seven-amino acid peptide with the sequence fMDVEAWL.
