Gal1+cox6+GFP+ADH1

To test the localization function of CoxVI, the C-terminus of CoxVI was fused to GFP. Besides,we use MitoTracker Red®CMXRos to stain the mitochondria and do an overlap with GFP. By observing the coefficient value, we can judge that if our leading peptide works.We adopted fluorescence test to have a visible look at where the fusion protein is located. The following microscope images were obtained. It was observed that green fluorescence concentrated in mitochondria stained by a specific stain, instead of diffusing in the cytosol.The reult proves that CoxVI can locate GFP into the mitochondrial matrix.

Figue1.GFP is targed to the mitochondria

COXVI is obtained from genome of saccharomyces cerevisiae, the other parts is from the kit provided by official
