Heavy chain human ferritin with his-tag and E-coil under the lacI inducible promoter

This heavy ferritin chain comes from humans. This part along with light ferritin (BBa_K1189024), form the ferritin nanoparticle, an iron-storage particle made up of 24 subunits. The formed nanoparticle is highly robust, remaining stable at extreme pHs and temperatures. The difference between light ferritin is that this chain contains a ferroxidase centre.

This nanoparticle can also be used as a reporter when the iron core is modified with potassium ferrocyanide to form Prussian Blue. The Prussian Blue ferritin can then act as a peroxidase mimic, similar to horseradish peroxidase, resulting in colour changes in the presence of hydrogen peroxide, and TMB or ABTS.

We added the lacI promoter (BBa_J04500), double terminator (BBa_B0015) and a his-tag in order for us to induce protein expression as well as purify it.
