Part:BBa_K2255003
Multi-Tag (Rfc 25)
This tag provides multiple fixation sites: a Strep-tag [1] and a histidine tag. Between those tag is a TEV protease cutting site [2].
This part was designed with the Freiburg (Rfc25) extension. Thus, it contains the restriction sites NgoMIV and AgeI that are compatible and allow the absence of a start and stop codon, which ease the assembly of multiple protein domain.
Usage and Biology
This part is usefull in our to purify the enzyme that use to disrupt the biofilm. Check out our [http://2017.igem.org/Team:Aix-Marseille/DEPS enzyme design page] to know more about our project.
GFP purification with a Ni column
Purification of [sfGFP] fusionned with this tag (BBa_K2255003), with the [Ni-NTA Spin Kit] (Quiagen). As you can see, mainly sfGFP is present after elution and most of the protein are gone with the wash. Thus, the his-tag of this part is functionnal.
