Part:BBa_K1926013

The mCHERRY UNIT: mCherry flanked by Vox

This part is the mCHERRY UNIT of cyclebow system including a degradation tag named DBOX, a fluorescent gene mCherry and an sv40 terminator flanked by homodromous recognition site of recombinase VIKA named Vox. The whole part can be cut off by VIKA. This part is the improvement of the Part: BBa_J06504，which is a plain mCherry. --[1]

Usage

You may use this part to:

1) Provide fluorescent red which can be quickly cut off by transient transfecting recombinase gene into nucleus;

2) Use it as a part of the flp-out system[1].

Source

The sequence of Vox and DBOX was retrieved from Addgene and got through denovo synthesis. mCHERRY and sv40 terminator were got from commercial plasmid: pentry dcas9 mcherry bira and pentry nls GFP/pcdna3.1, respectfully.

Construction Design

The mCherry with tags and RTSs are constructed using PCR and oligonucleotide ligation by the following procedure. Our UNITs all contain XbaI and SpeI enzyme sites, so we can easily line up the UNITs using 3A assembly.
