Western blot
Idea
LovTAP-VP16 contains the C domain of VP16, therefore with a VP16 antibody it is possible to detect LovTAP in a Western blot.
Experimental Setup
We transfected the CHO (strain DG44) cells the evening before the experiment with 100% pcDNA3-LovTAP, turned on the blue light for 2 hours the next morning, took samples and performed the Western blot using [http://2012.igem.org/Team:EPF-Lausanne/Protocol/Western_Blot this] protocol. We did the same with HEK cells.
Results
Lane 1: VP16 positive control (VP16 protein) Lane 3: Untransfected CHO cells Lane 4-5: LovTAP-VP16 transfected CHO cells Lane 6: Untransfected HEK cells Lane 7-8: LovTAP-VP16 transfected HEK cells.
We can clearly see that the VP16 antibody recognized a VP16 domain in lanes 4-5 and 7-8, which are the LovTAP-VP16 transfected cells. We can thus say that the cells expressed a protein with a VP16 domain.
Flow cytometry
Idea
The photosensitive lov2 domain in LovTAP-VP16 has an exploitable characteristic which is purple autofluorescence. We decided to use this feature to detect by flow cytometry if the lov2 domain is present and folded correctly.
Experimental Setup
Results
On the left: Untransfected cells. On the right: LovTAP-VP16 transfected cells.
