Lab Notes

We conducted a lot of experiments at Komaba Research Campus.

September 12th

DNA Origami

We made a solution of DNA origami. We annealed these tubes from 90°C to 20°C for 2800 seconds.

(µL)

M13 Staple Mix TAE 10x Mg2+ mQ Total Amount
A 3.00 7.20 1.80 2.25 3.75 20.00

C 3.00 10.80 1.80 2.25 0.15 20.00


September 13th

DNA Origami

We observed DNA origami which we made September 12th by AFM.

  • AFM image of A


  • AFM image of C

As you can see the picture above, the origami was not structured well. Therefore, we decided to do the same experiment in different condition.


September 14th

DNA Origami

We made DNA origami solution again. We annealed these tubes from 90°C to 20°C for 2800 seconds.

(µL)

M13 staple mix Mg TAE mQ total amount
1.66 2.16 2.5 2 11.68 20


We observed again, and the origami was successfully structured.


Bistable System

We did the first experiment of the bistable system. This time, we tried making the stable state but didn't to try switching. Group1 and 2 were with NBI, the nickase. Group1 and 3 included VII at the beginning, while 2 and 4 did XII. We got good results. Different stable states were observed according to their intial states in Group1 and 2. We kept these tubes in 42°C for 25 hours.

September 19th

DNA Origami

  • Normal DNA Origami

We prepared two types of DNA origami solution. The purpose of the experiment was to compare the different result from the different concentration of the solutions. We annealed these tubes from 90°C to 20°C for 2800 seconds.

  • DNA Origami with Enzymes

We use enzymes in bistable system, therefore we make sure that the enzymes do not destroy the DNA origami. We put nickase, polymerase and exnuclease with DNA origami and left them in the PCR. The concentration of original DNA origami was 10x and 15x.

  • DNA Origami with BSA

We are also worried if BSA interrupt the AFM and we can not get clear images of DNA origami. Therefore, we prepare the solution for September 20th. The concentration of original DNA origami was 10x and 15x.

(µL)

Bistable System

We wanted to know the best concentration for the bistable system. Two different DNA strands, "XII" and "VII", were used for the experiment. We searched the best concentration of CvII and CxII separately.
CvII is the template for doubling V, and CxII is the one of X. "X to inhV" is the template for making inhV DNA from X, and "V to inhX" is the one of V. We change the concentration of CvII and CxII in order to find out the best concentration of them. We kept these tubes in 42°C for 25 hours.

  • The Experiment of VII

When several hours passed after putting these tubes in PCR, we injected XII 0.40µL in each VII tubes and VII 0.40µL in each XII tubes. Then we kept these tubes in 42°C for the rest of hours.


September 20th

DNA Origami

We observed three types of DNA origami which were made in September 19th. The three types of DNA origami is normal DNA origami, DNA origami with BSA and DNA origami with enzymes.

  • Normal DNA Origami

We observed the origami by AFM, but the structures of DNA origami were destroyed as you can see from the picture below.

Normal Origami


  • DNA Origami with BSA

We need BSA for the bistable sytem so that we had to make sure that we can see the DNA structure when there are BSA in the liquid of the origami. Before we observed the origami with BSA by AFM, we rinsed 5μL of the origami liquid with 40μL of buffer for 4 times. Therefore, as you can see from the picture below, BSA did not disturb the observation of AFM, we can get the clear picture of DNA structure.

Origami with BSA


  • DNA Origami with Enzymes

In the bistable system, we use three kinds of enzymes so that we had to make sure that the enzymes do not destroy the origami. As the result, we could see the DNA structure clearly, which proved that the enzymes do not destroy the DNA origami. Moreover, we observed the well-done origami structure in this experiment.

Origami with Enzymes


September 24th

Bistable System

We change the condition of the bistable experiment and put some tubes in PCR. The concentration of Bst and X to inhV were different from the same experiment of September 19th. We kept these tubes in 42°C for 10 hours.

  • The Experiment of VII

When several hours had passed since we put them in PCR, we injected XII 0.40µL in each VII tubes and VII 0.40µL in each XII tubes. Then we kept these tubes in 42°C for the rest of hours as the bistable experiment we did before.

We could not observe the radical change of the concentration which is necessary for the bistable system.

September 28th

Indirect Bistable System

We could not get a good result of the bistable system so that we change several part of the system. We introduce two types of DNA, "NII" and "DII", and two types of templates, "N to X" and "D to V" in the system. We change the concentration of "N to X" and "D to V", which are always the same concentration. We also kept these tubes in 42°C for 10 hours.

When several hours had passed since we put these tubes in PCR, we put NII in tubes of VII and DII in that of XII so that the concentration of V or X might not change radically. After putting DNAs, we kept them in PCR for the rest of hours.

We could not get good results because the inhibition of V to X was too strong. We decided to do the same experiment whose concentration of V to inhX is lowered.

October 1st

Indirect Bistable System

We conducted the same experiment as what we did in September 28th. We got enough information about the experiment of VII, so we only conducted that of VII. The purpose of the experiment is to find out the best condition of the experiment of XII. We changed the concentration of CvII and X to inhV and compared the results. We kept these tubes in 42°C for 10 hours.

  • The Concentration of X to inhV: 10.00nM.

Although we conducted the experiment, the concentration of "D to V" and "N to X" was so high that we could not get the proper result. Therefore, we decided to do the experiment whose concentration of the templates are lowered.

October 2nd

Indirect Bistable System

We lowered the concentratinons of D to V, and N to X. Today, we conducted experiments in order to find out the ideal concentration of "X to inhV". We kept these tubes in 42°C for 10 hours, and injected once each wells.

From the experiment, we find out that the tube which contain X to inhV show the radical change of concentration of VII and XII. Therefore, the concentration of X to inhV would be introduced to the experiment of the bistable system which would be held after October 2nd.


Trioscillate System

To investigate the ideal condition of trioscillate system, we conducted experiments which checks three parts of this system. The cycle of the trioscillate canbe clockwise and anticlockwise so that we conducted the both experiment. All of the experiments below is the same cycle, X -> V -> Q. Inhmix contains V to inhX, X to inhQ and Q to inhV. We kept them in 42°C for 5000 minutes.

In the experiment, we could not find out the best concentration of CxII, CvII and CqII. The concentration of XII, VII or QII did not change steeply so that we could not introduce the concentration to the trioscillate system.

Indirect Bistable System

In the experiment, we investigated the ideal temperature for the bistable system. We made two solutions, one starts from "X" and the other from "Y", and observed them at 6 different temperatures, 41.6, 42.5, 43.8, 45.6, 46.8 and 47.6°C. We kept these tubes in PCR for 40 hours.

In 41.6°C, the concentration of XII or VII change most radically. It means that, in that condition, the concentration of VII decreased most steeply in the experiment of A, and that of XII decreased most steeply in the experiment of B. The curb of the decrease became calmer and calmer when the liquid temperture went up, and, in 45.6, 46.8 and 47.6°C, there was no curb of the decrease.

Modified Origami

We design modified origami and annealed them for about an hour in PCR. On the surface of one origami, there are 15 hammerhead structure and 1 hairpin structure. Therefore, we order DNA which composes the structures and replace staple strands of normal origami with them. We drew three lines on the surface by the hammerhead structures, and one line consisted of 5 structures which have the same number of bases. The numbers of bases of the structures are 16, 18 and 20. We anneal them from 90°C to 20°C for 2800 seconds.

Modified Origami

We made modified origami in October 3rd and keep them at the laboratory room temperture. We observed the modified origami by AFM and we get the clear picture of lines on the surface of the origami. The three lines on the surface shows the fact that the modified origami which have hammerhead structures was well-done. Also, the picture below proved that we can observe a hammerhead structure as a dot so that we can draw a picture on the origami surface.

Trioscillate System

We tested the whole trioscillate system. To investigate the ideal condition, we conducted the experiment of both direction of inhibition (V-|X-|Q, V-|Q-|X) and searched the concentrations of CxII, CvII and CqII. We kept these tubes in 42°C for 10 hours.

In the experiment, we found out the good condition of the experiment of V-|X-|Q. However, the result from that of V-|Q-|X was not accurate enough to introduce to the traioscillate system. Therefore, we decided to do the experiment of V-|Q-|X again.

As the result, we found out that 0.50μL of CxII was too small, but 1,00μL of that was too big. We decided to search the best concentration of CxII between 0.50μL and 1.00μL.

October 18th

According to the 10/18 experiment, [CxII] = 25nM is too low and [CxII] = 50nM is too high. So today we investigated the best concentration of CxII.

As a result, lower concentration of NBI seems to be good. That is because, if there are a lot of NBI, inhibition works too much, and the reaction network does not oscillate.
