Part:BBa_K243032

Fok_a-Venus

This part is like part the protein domain Fok_a from our universal endonuclease, but it has an additional linked YFP-marker.

Usage and Biology

The addition of a fluorescent protein(Venus) to the protein construct, enables the detection by fluorescence microscope and new way of purification by GFP-trap column.The Venus protein was fusioned C'terminal to the protein domain, so when the protein is expressed the fluorescence signal of the Venus protein can be seen.

Detection

There was a strong fluorescence signal under the fluorescence microscope after the induction of the cells with IPTG.The E.colis(RV308) were excited with the wavelength 505nm and then some pictures of the fluorescencewere made.

The cell extract were check by SDS-page to get information about the expression of proteins.
