Design Notes

We wanted to create a multi-tag with a his-tag (attachment to Co or Ni column) and a Strep-tag [1] (wich has an affinity towards Strep-Tactin®). Between those tag, we added a TEV [2] cutting site to give the possibility to decrease the length of this multi-tag.

Our tag is composed of StrepTag-TEV-6His, which can be constructed as GSG-WSHPQPEL-GSG-ASQFYLNE-GSG-HHHHHH

Glycine and serine residues are added to the sequence in order to give flexibility and space between the tags and the cutting site.

We retro-translated this sequence and optimized it for E. coli.

Source

This part is made with the consensus sequence of the streptavidine tag, the histidine tag and the TEV protease cutting site.
