Part:BBa_K313008

pT7 - Cre recombinase generator

It is the generator of the Cre recombinase.

Cre is transcribed by the T7 RNA polymerase.

By this construct, we conducted recombination experiment along with "Cre recombinase assay device". (Please see here.)

This construct also serves as a positive control of "Cre generator with terminator" series as shown the table below.

Other Cre generator with terminator parts

number	description	Subparts compositon	PartsID
1	Cre generator with single terminator	pT7-t90%-rbs-cre-dt	BBa_K313017
2	Cre generator with double terminator	pT7-t90%-t90%-rbs-cre-dt	BBa_K313018
3	Cre generator with weak single terminator	pT7-t80%-rbs-cre-dt	BBa_K313021
4	Cre generator with weak double terminator	pT7-t80%-t80%-rbs-cre-dt	BBa_K313022

Now we are planning to conduct further research, seeking for appropriate terminator for 4C3 leak-switch.

verification experiments

This part was ligated with loxP-gfp-loxP sequence and transformed into E.coli. By incubating E.coli, then extracting plasmids, and sequencing them, it was proved that gfp sequence flanked by loxP sequence was removed. As a conclusion, cre generated by BBa_K313008 is able to catalyze site specific recombination reaction.
