Problems solved by technology

But so far, diabetes has no cure and requires life-long medication
Diabetic patients need to take hypoglycemic drugs orally or inject insulin every day to maintain blood sugar stability, especially if insulin injection cannot achieve a controlled release of insulin, it is very easy to cause the risk of hypoglycemia

[0183] (4) Preparation of Escherichia coli Competent Cells

[0184] All solutions and consumables used for the preparation of competent cells are sterilized by high temperature and high pressure.

[0185] 1. Streak Escherichia coli DH5α strain on a plate without antibiotics, and culture it upside down at 37°C for 12-16 hours;

[0186] Pick a single colony and place it in a 2mL LB shaker tube without any antibiotics, shake it at 180rpm at 37°C overnight;

[0187] 2. Take 1mL of the bacterial liquid and transfer it to a 250mL Erlenmeyer flask with LB medium for expansion culture (according to the ratio of 1:100 to expand the culture), shake the culture at 180rpm at 37°C for 2-3 hours until the OD600 is between 0.4-0.5;

[0188] 3. Transfer the culture medium into a centrifuge tube, place it on ice for 10 minutes, then centrifuge at 3000 rpm for 10 minutes at 4°C (the centrifuge needs to be pre-cooled in advance), and carefully discard the supernatant;

Abstract

The invention discloses a far-red light gene circuit expression control system. The far-red light gene circuit expression control system comprises a photoreceptor for sensing a far-red-light light source, a processing device for processing a signal transmitted by the photoreceptor and an effector for responding the signal transmitted by the processing device. The invention further discloses a gene circuit remote regulation and control system; the gene circuit remote regulation and control system comprises the far-red light gene circuit expression control system, a control device for sending out a remote control instruction and a far-red-light light source device. The invention further discloses application of the far-red light gene circuit expression control system and the gene circuit remote regulation and control system to treatment of diabetes mellitus. The invention further discloses a eukaryotic expression vector, an engineered cell or an engineered cell transplanting vector, which contains the far-red light gene circuit expression control system. The far-red light gene circuit expression control system can be used for rapidly regulating and controlling gene expression and has the characteristics of ultra-remote control, intelligent regulation and control of gene expression quantity, high regulating and controlling expression times, high time-space specificity, strong tissue penetrating power, good insulating property, no toxic or side effect and the like.
