GIP promoter

GIP promoter is anticipated in current literature that it can only be used in several certain types of cells like intestine cells, but we proved that it can function will in 293T cells which are usually used in labs.

1.Pattern diagram

Fig.1 The model diagram of CHREBP-LUC

2.Experiments

2.1 Method

We use LUC as report gene, test its real-time luminescence value at 560nm wavelength with specific devices and detect the expression level under different glucose concentration.

2.2 Result

GIP promoter is induced by glucose and the expression level rises along with the raise of glucose concentration.

Fig.2 Changes of LUC expression over time after blue light irradiation with different glucose concentrations

3.Caution

Use medium without glucose when paving in case of the effect caused by glucose residue
