Monday 11 June
Working in a lab, first approach!
After becoming familiar with all the machines, chemicals, pipettes and the thousands of tubes that surround us, we place "tidily" our own material all over the laboratory and set some basic rules for the labeling, the waste products disposal and safety stuff. Planning the week is essential, so we spend some hours looking through all the BioBricks we want to use and how we have to mix them to make our bacteria work propperly. Restriction enzymes, antiobiotics, promoters, reporters...such a nice chaos.
Show Monday protocols
Monday Protocols
No protocols used today,but we're gathering some for the next days. Give us some time!
Tuesday 12 June
We prepare the competent cells from the inoculum we made yesterday, following a protocol that seems to be quite easy and simple. At the same time, some other members of the group shut theirselves up in the kitchen to cook some litres of LB-agar with different antibiotics and prepare the Petri dishes. Once they're ready, we seed the competent cells.
Tuesday Protocols
Competent cells:
1. Grow cells in tubes with 3 ml of LB o/n at 37ºC with agitation
2. Transfer the cultures to 50 ml of LB and let grow until it reaches an OD of 0,5
3. Cool it in ice for 10 min
4. Transfer 12 ml to steril tubes
5. Centrifuge at 3000rpm for 10 min and remove the supernatant
6. Resuspend cells in CaCl2 100mM (add 5ml to each tube)
7. Add 7ml of CaCl2 100mM (4ºC) to each tube so that the final volume is 12 ml
8. Incubate in ice for 30 min and centrifuge at 4000rpm for 5 min. Remove supernatant.
9. Resuspend all the collected cells in 5 ml of CaCl2: add 5 ml to the first tube, resuspend and put it into the second tube, and so on until all the pellets are contained in the final tube with 5 ml.
10. Store with glycerol at -80ºC (30ul glycerol + 170 ul cell culture)
Wednesday 13 June
To test our competent cells we split into three groups to transform bacteria with all the BioBricks we have, following the enclosed protocol. We seed the transformed bacteria in dishes with the appropiate antibiotic and let them growing overnight. We keep talking about the better ways to assemble the BioBricks once we get them. So many things to take into account and so many materials haven't come yet...

Thursday 14 June
We entered the laboratory and ran excitedly to see how our transformations had gone, just to find out none of the bacteria had grown. What a disappointment...We go to the department of Genetics to cry a little and get some competent cells to start over.They also give us their own protocol to try again, and a control plasmid for transformations (S3139). Competent cells in hand, we do the transformations again with the BioBricks and leave growing o/n at 37ºC. Hope tomorrow there's something else than LB-agar in those dishes...

Friday 15 June
OH YEAH!There they are!It seems our transformation has been a success. But we don't have all the materials needed to try our new protocol to prepare competent cells, so we spend the evening cooking some more LB, preparing LB-agar dishes and understanding how the autoclave works (we have a love-hate relation with that stupid machine).

Weekend 16-17 June
Sunday evening,38ºC in Seville, and here we are preparing inoculums of all our transformed cultures to keep them growing in LB+antibiotics o/n at 37ºC. Who said weekend was a break?
