<h4>Discussion:</h4>
<p>
The positive and negative controls are as expected.
For the F8 reaction, we can see little smears and some nice bands.
The amplified F8 DNA was expected around 7000 bp, for which we do see a small band, but the band around 1000 bp is not the desired product.
Based on these results we decided to extract the DNA out of the gel and amplify it in order to get a lot of ‘pure’ factor 8 DNA.

<h4>Experimental:</h4>
<p>
A miniprep was performed on 2mL of all 10 liquid cultures.
2.5 uL of each XL1Blue plasmids and 5 uL of the Top10 plasmids were degraded with Xho1 and EcoRI and analysed via agarose gel electrophoresis.
</p>

<p>EcoRI digestion:</p>
<img class="journal-img" src="https://static.igem.wiki/teams/5342/images/notebook/mrna/plasmid-amplification-1.webp" alt="Plasmid Amplification">
<p>
The EcoRI digestion is to check the structure of the plasmid.
Four bands were expected (347bp, 1725bp, 4688bp and 5323bp) and that is also visible on the gel.
</p>
<p>Xho1 digestion:</p>
<img class="journal-img" src="https://static.igem.wiki/teams/5342/images/notebook/mrna/plasmid-amplification-2.webp" alt="Plasmid Amplification">
<p>
Meant to linearise the plasmid. One band is visible with the length of the whole plasmid (12.1kbp) as expected.
Both digestions look good, the next step is to do a larger scale Xho1 digestion to collect more linearised plasmid for in vitro transcription.

<h4>Experimental:</h4>
<p>
4 enzyme digestions with a volume of 150 uL were prepared using plasmids isolated from XL1Blue.
11.9 uL pcDNA was used to reach a final concentration of 9ng.
The digested plasmids were purified using a spin column.
The concentrations of the purified product were measured to be 79.9, 96.6, 94.7 and 88.8 ng/uL.
The purified products were put on gel (110V 50 min) to check the quality.
</p>
<p>
Note: the samples were floating out of the wells, so we prepared them again with a 5:2 sample to dye (double the amount of dye)

<h4>Experimental:</h4>
<p>
10 epps with each 20uL mastermix were prepared.
1uL from 5 different DNA templates (F8 1-4 pcDNA see F8 cloning and GFP cDNA see GFP PCR) to reach an approximate final concentration of 10nM.
For every different DNA sample, one epp got 2uL mutated (look up specific type) T7 polymerase and the other 4uL.
5uL of all samples was mixed with 2uL loading dye and run on an agarose gel (110V 40 min).
</p>
<img class="journal-img" src="https://static.igem.wiki/teams/5342/images/notebook/mrna/in-vitro-1.webp" alt="in vitro">
<p>
We try to recycle our gels as much as possible to reduce waste, the crossed out lanes are from a different experiment (refer to FVIII plasmid purification).
</p>
<h4>Discussion:</h4>
<p>
It is weird that 1, 2 and 4 with 2uL T7 did not show a lot of transcription while 3 seems to have a lot, because they should practically be the same. Overall, the reaction seems to work better with 4uL T7, so we will continue with that.
The FVIII RNA was expected to be longer (7000 instead of 1200). This could be the result of RNA degradation or self splicing, but it could also be because of the properties of the gel and because RNA is not linear.
In addition, the GFP RNA did not work out that well in both cases. it could have something to do with the template. It turned out that the calculations on the amount of GFP template were incorrect, so in the next experiment the correct amount should be added.

<p>
10 epps with 20 uL IVT mastermix were prepared.
If both 4uL T7 was used for both varieties.
1 uL of F8 DNA template was used from both template samples, 1.5 uL of the diluted GFP template was used to reach the right amount of template.
For samples containing RNase inhibitor, 0.5 uL ribolock was used.
</p>
<img class="journal-img" src="https://static.igem.wiki/teams/5342/images/notebook/mrna/in-vitro-2.webp" alt="in vitro">
<h4>Discussion:</h4>
<p>
First important to note is that during the pipetting of well 3 the pipet point fell, so any abnormalities could be linked to that.
When comparing well 7 and 8, the effect of RNase inhibitor is shown clearly.
Compared to the previously used mutated T7, the WT T7 shows a higher yield for both FVIII RNA and EGFP RNA.
The bands are still very smeared, especially the FVIII RNAs, either due to RNA secondary structures or low purity.
To investigate this, a denaturing agarose gel should be performed.
In addition, transcription using WT T7 and RNase inhibitor can be scaled up.

<h4>Discussion:</h4>
<p>
The nanodrop result shows a promising result, the concentration of the purified RNA is high enough to continue with further experiments.
To be certain/to see that the purification worked well enough it is decided that the purified sample will be ran on a gel.

<h4>Experimental:</h4>
<ol>
<li>To prevent high concentrations of RNA on the gel, the 10 uL sample was diluted with 850uL MilliQ.</li>
<li>5uL of the diluted sample was combined with 15uL of denaturing RNA loading buffer, incubated at 65C for 5min.</li>
<li>The quality of the RNA was investigated by a denaturing agarose gel (110V, 50 min).</li>
</ol>
<h4>Discussion</h4>
<p>
The gel showed no bands or smears, possibly because the sample was too diluted.
A second trial for the purification needs to be done to try and understand this result.

<h3>2nd Trial mRNA Purification.</h3>

</ul>
<h4>Experimental:</h4>
<ol>
<li>We tried to reconcentrate the diluted RNA sample (see RAD116) by percipitating it with 200uL ice cold isopropanol and centrifuging at 27500 rfc at 4C for 5 min → did not do anything.</li>
<li>To the remaining 20 uL of sample 1* (see RAD115), 20 uL phenol/chlorophorm was added and shaken.</li>
<li>The sample was centrifuged at 12000 rfc, 4C for 2 min</li>
<li>The top (aqueous) layer was transported to a new epp together with 20 uL new phenol chlorophorm and shaken.</li>
<li>Centrifuged at 12000 rfc, 4C for 2 min.</li>
<li>Top layer was added to 50 uL ethanol, shaken.</li>
<li>Centrifuged at 29000 rfc, 4C for 10 min.</li>
<li>Supernatant was removed and the palete was washed with 40 uL ice cold ethanol.</li>
<li>Centrifuged at 29000 rfc, 4C for 5 min.</li>
<li>The supernatant was removed and the palete was air dried.</li>
<li>A small bit of the palete was removed, and resuspended in 10uL milliQ for analysis.</li>
<li>The rest of the palete is stored in the freezer, before use it should be resuspended in milliQ.</li>
<li>The fragment of the palete was analysed on a denaturating agarose gel (110V, 50min).</li>
<li>Absolutely no bands were observed on the gel.</li>
</ol>
<h4>Discussion</h4>
<p>
The problem is most likely not caused by a too dilute sample, but it could be the result of the buffer being multiple days old.
It might have picked up RNases that have degraded the sample while in the gel.

<li>5uL of the sample was run on a denaturing agarose gel (110V 50min)</li>
<li>No bands were observed (in the picture the first column should have been the purified GFP, the other 2 bands are non purified F8 samples).</li>

<h4>Discussion</h4>
<p>
The problems are not caused by a diluted sample or by an old buffer. It might be a more fundamental problem with the purification method.
We might need to look for a new way to do the purification.
