Applications of BBa_K3117029

Usage of the composite part by the iGEM team FAU_Erlangen

The construct 1 (K1) was synthesized by IDT. It was cloned into the expression vector pSEC/tag2/Hygro\C\-\OK by Gibson Assembly. Our proteinsequence was under control of the CMV promotor ensuring a high-level constitutive expression. Afterwards, the construct was brought into HEK293T cells with either calcium phosphate transfection or lipofection. The accuracy of the inserted DNA after cloning was confirmed with sequencing. The data is depicted in Fig. 1.

Fig. 2 shows the western blot of the harvest after transfection into HEK 293T cells. For detection, the His-Tag in the K1 sequence (BBa_K3117005) provides the opportunity to be used as a target for a primary antibody in a western blot. K1 can be seen at expected height (54 kDa). The presence of K1 in the medium proves the function of the Igk leader (BBa_K3117006), which is directing the protein into the secretory pathway.

Furthermore the His-Tag (BBa_K3117005) in K1 allows purification of the protein with HisTrap columns. The western blot after this purification is shown in Fig. 3, showing the remaining presence of the protein after this step.
