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%)

02-08-2010

Other

  • Made some plates with GLY medium and Agar.

Asaia

Today 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.

Drosophile

we 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

Immunotoxin

We 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...


Wiki

We did a lot of work on the wiki but we haven't downloaded it yet.


Asaia

We keep counting the drosophila and taking pictures with the GFP filter.


Biobrick

  • Digestion of the plasmid containing the origin + one resitance (either Amp, Kan or Ch) and digestion of the vector i51020
  • Ligation ofthe the different parts (one insert in one back bone vector) => origin+resistance+backbone_vector_for_biobrick
  • Plating over night => we obtain something on the plate for the ori + amp nothing on the other

04-08-2010

Immunotoxin

Henrike verified the primer sequences for us and ordered them --> they should arrive on Friday or Monday.

Asaia

  • The asaia transformation we let in the incubator since 02-08 are now showing colonies! As expected and verified under the fluorescent microscope, they express GFP.
  • Transformed Asaia with the pB129421248??? plasmid from E. coli to see whether it works in Asaia.

Other

  • Continued counting the dead Drosophilae
  • Made 2l of liquid gly medium
  • Put 2 5ml cultures of recovered wt-Asaia in the incubator to make competent cells


Biobrick

  • Make 5 ml miniprep to verify the ori + ch + i5010
  • Make negativ control for the ori + ch + i5010 on Lb+Amp plate (as the ori + amp were in the A3 backbonevector)

05-08-2010

Other

  • Continued counting the dead Drosophilae and taking pictures.
  • Measured the OD of the two 5ml wt-Asaia cultures (4.1 and 4.7),diluted the cultures to obtain a solution with OD 0.6 tomorrow morning and finally make competent cells

Biobrick

  • The previous ligation didn't work at all, so we made a new ligation with ori + res + i51020
  • We replated the collonies that had well grown on the plate the 28.7 to keep them in glycerol

Asaia

  • We made a culture to make them competent toworrow (06.08)

06-08-2010

Biobrick

  • We obtained colonies on the plate from yesterday (Asaia origin + Resistance). We made a miniprep from that and stored some on Glycerol in the -80°C freezer. With the same miniprep we run a gel. Result :

Asaia

  • Measured the OD of our Asaia cultures. They were 1.24 and 1.95. We diluted them again and then started the procedure to make competent cells. Finally we got 22 aliquots of 150ul.
  • Had fun with the liquid nitrogen left over...
  • Plated one aliquot on Gly without AB to make sure the now hopefully competent cells survived the procedures.
  • We made some stock of "asaia origine + Resistance (Kan, Cm, Amp) + BackBones Vector" in the -80°C fridge.
  • We've transformed Asaia with plasmid C3 + E-coli Origin + Resistance and the colonie didn't grow so we can say it out and loud :
E-coli Origin doesn't work in Asaia

06-08-2010

Biobrick

09-08-2010

Biobrick

Asaia

  • We made pre-culture and plates (on both Kan and Gly alone) of the recovered WT Asaia
  • Made PCR of the promotor + RBS and ran gel -> it worked

10-08-2010

Immunotoxine

We'll made some GLY stock of E-coli containing the immunotoxine plasmid (shiva). So today we transform E-coli with the plasmid and we plated on Amp overnight.

Biobrick

We try to begin to construc two new biobrick today but we made mistake. We'll start again tomorrow.



11-08-2010

Immunotoxine

We've pick up some colony of transformed cells from yesterday and make liquid culutre of them. Tomorrow we'll make some GLY stock and a gel to control. With this stock we can begin to work safely with the immunotoxine.

Asaia

To test our asaia origin sequence, we take a BV with (1) asaia origin (2) Amp resistance (3) death casette and we will throw away the death casette and just transform asaia with this simpel plasmid. Today we just make a liquid culture from a GLY stock with E-coli containing this plasmid.

Biobricks

We begin to construc a new Biobrick containing (1) Base Vector (2) Strong or Weak promotor (3) RBS. Today we made digestion, ligation and E-coli transformation. Plated overnight on Amp.

Drosophile

Persistence of bacteria in drosophilia's gut. We infected (fed) flies with Asaia. We also infected flies with persistant or pathogenic bacteria (control experiment). Then we crushed, diluted and plated infected flies after 3h hours from infection. We will plate flies after 24 and 48 hours as well and see how many colonies appear in function of time.
