Abstract: The fluorescent proteins(FPs)and their color variants have been widely used in cell biology, molecular biology and medicine. Various new technologies based on these proteins such as bimolecular fluorescence complementation (BiFC), fluorescence resonance energy transfer (FRET)-based techniques and optical highlighter are enlightening the whole biology technology. In this paper, we used transposon-based mutagenesis and flow cytometry to verify thirteen tolerate sites of mCherry with five amino acids inserted which fluoresced red. The inserted variants with fluorescence can be served for BiFC and provide more selective sites for designing of bio-sensors.

Key words: Red fluorescent protein, Short-peptide, Inserted sites
