We have proved that Insulin can be processed and secreted outside the cell in 293T cells.

Fig.1 The model diagram of 9XUAS-Insulin

In the experiment, we used an ELIAS kit specially designed to detect human mature insulin to detect cell eliquidation.

Insulin can be processed and secreted outside the cell in 293T cells.

Insulin is not suitable for long time preservation under the best culture temperature of cells (37℃). In the mean time, cells would also consume some of the expressed insulin. So the best tst time for Insulin is approximately 24 hours after transfection, it is relatively shorter than the test interval of LUC.
