In Vivo Imaging of Far-red Fluorescent Proteins after DNA Electrotransfer to Muscle TissueDNA electrotransfer to muscle tissue yields long-term, high levels of gene expression; showing great promise for future gene therapy. We want to characterize the novel far-red fluorescent protein Katushka as a marker for gene expression using time domain fluorescence in vivo imaging. Highly efficient transgenic expression was ob......阅读全文
