Design notes

This part was created by fusing the heavy chain (BBa_K1189025, P02794 [UniParc]) and light chains (BBa_K1189024, P02792 [UniParc]) of human ferritin together. It is expressed under the LacI promoter (BBa_J04500) and has a his-tag for protein purification. An E-coil (BBa_K1189011) is included in order to allow binding of parts containing the respective K-coil (BBa_K1189010). This particular part is expressed under a strong RBS and the LacI promoter. Note that this part is identical to BBa_K1189037, say for the exclusion of a hexahistidine purification tag. Please see BBa_K1189037 for full characterization of this part.

Source

We synthesized heavy ferrtin (BBa_K1189019) and light ferritin (BBa_K1189020) from a commerical synthesis company. These parts were optimized for expression in E. coli K12. These two elements were extracted via PCR, the pSB1C3 backbone was isolated with PCR, and these linear fragments were assembled into BBa_K1189018 using isothermal assembly.
