Human ferritin di-subunit with E coil w/ LacI promoter

This part was created by fusing the heavy chain and light chains (PARtx2) of human ferritin together. It is expressed under the lacI promoter (PARt) and has a his-tag for protein purification. An E-coil (PARt) is included in order to allow binding of parts containing the respective K-coil (PART).

This construct can be used as a reporter through a modification of the iron core to form Prussian Blue.

The resulting molecuel can then catalyse the formation of radicals from hydrogen perxoide, which can then cause a colour change in substrates such as TMB or ABTS.

Something about scaffold…
