Western blots and TLC scanning results for Rap2A with radioactive FPP in vivo. Western Blot and corresponding scans from TLC linear analyzer of wild-type HA-Rap2A-fusion protein (lane 1) and HA-Rap2A C180A (lane 2) immunoprecipitated from HeLa-cells, treated with lovastatin after transfection with the respective plasmid construct and exposed to ³H-FPP. There is significant incorporation of FPP into the wild-type protein (lane 1), but no signal is detected for the C180A mutant (lane 2), demonstrating the applicability of the approach for in vivo labeling experiments.
