How to use the Notebook
This is a NOTEbook and not a LABbook. Here you can describe what you have done during your exciting day. If you want to have more details you can look in the IRL Labbook. Use ctrl+F to find something ;)
template of the day
For each new day in the lab you must create a new date in the notebook. To do so, copy-paste the following template:
= 02-08-2010 =
{| cellspacing="15"
| style="width: 33.33%" valign="top" |
== Other ==
It rain a lot today
| style="width: 33.33%" valign="top" |
== Asaia ==
Today I speak with an asaia and she answer to me ^^
| style="width: 33.33%" valign="top" |
== Drosophile ==
|}
|
Here are some useful explanations : 1. The date format is important! 2. Just after the date, put the following two lines :
{| cellspacing="15"
| style="width: 33.33%" valign="top" |
3. Beetween each subtitle, put this line : | style="width: 33.33%" valign="top" | 4. To end the day just put : |} 5. Of course the text "width:33.33%" must be adapted on how many subtitle you have (for instance 4 subtitles = 25%) |

AsaiaToday we transform competent Asaia with a GFP + kanamycin (resistance) following this protocols. We plate it and we'll waiting 2 days to see if it works. we do digestion to create our first biobrick. We will make the ligation and the transformation in E-Coli tomorrow. |
Drosophilewe count the drosophile and take photos with the fluorecense microscope. In some tubes the filter has detached so the expermiment for those tube are finished. |
03-08-2010
ImmunotoxinWe have designed primers that overlap, generating a promoter and ribosome binding site. We want to put this in a vector which would be our basis to add other genes, for example our immunotoxin. We designed a strong promoter+RBS and a weak one, just in case the strong one generates too much immunotoxin and kills the bacteria...
|
WikiWe did a lot of work on the wiki but we haven't downloaded it yet. Tomorrow you will see!
|
AsaiaWe keep counting the drosophila and taking pictures with the GFP filter.
