Applications of BBa_K3117006 by the iGEM team FAU_ERLANGEN

In our project the Igk leader was added to three of our composite parts (BBa_K3117026, BBa_K3117030, BBa_K3117029) for the secretion of our desired proteins into the supernatant, after transfection into HEK 293T cells.

Figure 2: Western blot of the harvest after transfection of HEK 293T cells with our parts (BBa_K3117026, BBa_K3117030, BBa_K3117029). Anti His-antibody was used for detection

In Fig. 1 the western blot of the harvest of HEK 293T cells can be seen. Those proteins were detected via their His-Tag. The presence of the proteins in the supernatant shows, that the Igk leader was able to direct all three proteins into the secretory way. All proteins had the expected size of around 54 kDa (K1), 42 kDa (K2a), and 41 kDa (K2b). The second band of K2b was unexpected, but does not alter the results that the Igk leader successfully directed our proteins into the extracellular space.

By adding this signaling peptide the protein of interest can be secreted in the supernatant after transfection and the basis for a proper protein folding can provided. Prior to secretion the Igk leader is cleaved of. Igk leader is normally fused to the N-terminus of the protein of interest. The Team 2019 FAU_Erlangen used the Igk leader sequence to secrete their proteins (bispecific antibodies)after HEK293T cell transfection.
