cI translational unit with His-tag
lambda cI translational unit with AraC/Lac promoter (BBa_K354000) and C-term His tag
This part is an improvement of the existing BBa_K327018 LVA tagged cI repressor protein. We added a his tag instead of the LVA tag in order to offer a convenient way to study the protein without damaging it. The his tag is located at its C-terminal, therefore having no effect on its function.
we used this part in order to identify our protein through western blot technique, using anti His-Tag antibodies. in the western it is apparent that without induction there is no leakage of the cI protein but upon induction we get a nice band indicating that the cI is expressed. The positive control we used was a model protein containing a His tag.
and coomassie staining of the gel.
part is synthetic. the cI CDS (Originated from the lambda bacteriophage) and the promoter were taken from the iGEM registry.
