Lab Weeks

For half a year we were working in the wet lab , developed a pipetting robot and simulated the molecular dynamics of our proteins . As well we would like to highlight certain social events which helped us to further improve our team spirit.

Our iGEM year started with weekly team meetings on tuesdays in January.
On February 27 and 28 we officially iniated the project with our Kickoff-Event in which teams have been formed and weekly teamleader meetings were set.

To teach the new members all the needed basics for working in the lab and genetic engineering in general, the experienced students offered classes like a snapgene workshop (March 4), how to use scifinder (March 12) and a cloning strategies workshop (March 17).


Lab Week 1: April 18 - April 24		This week, we organised the lab work before the actual work started.
		Robotics Meeting with the people interested in the technical part of the project, discussing the task and the possible ideas.

		We met on Tuesday with the whole team.


Lab Week 12: July 4 - July 10		Killswitch BBa_K1976022: The ligation product was transformed into E. coli BL21 via heatshock for protein expression and SDS PAGE.
		Robotics We have some problems assembling the chassis. Some parts need to be adapted. We like to have as much active measuring area as possible. The first 3D printed parts for the syringe pump are ready and we need to redesign some parts. The optics require IR light from underneath. Next week we are discussing the details of the construction
		We met on Tuesday with the whole team.

		A guest from Milan arrives to get an impression of how iGEM works and help out in our lab - her name is Laura. She wants to introduce iGEM to her university as well and build a team there.


Lab Week 14: July 18 - July 24		miniColicin The BBa_K1976050 was made by performing a PCR on a product synthesized by IDT, using the primers M_RBS_DNAse_FW and suffix right. Following that another PCR was performed using prefix right and suffix right and digesting it using EcoRI and PstI. Following that it was ligated into the backbone pSB1C3 which was digested the same way and dephosphorylated, using our standard protocol for the antarctic phosphatase. Following that using the standard T4 protocol, these fragments were ligated together. E. coli Top10 were then transformed with the ligated plasmid.

Lab Week 15: July 25 - July 31		miniColicin The BBa_K1976051 was made by performing a PCR on a product synthesized by IDT, using the primers M_RBS_DNAse_FW and suffix right. Following that another PCR was performed using prefix right and suffix right and digesting it using EcoRI and PstI. Following that it was ligated into the backbone pSB1C3 which was digested the same way and dephosphorylated, using our standard protocol for the antarctic phosphatase. Following that using the standard T4 protocol, these fragments were ligated together. E. coli Top10 were then transformed with the ligated plasmid. Following that a colony PCR was performed to check for the proper band height. Killswitch BBa_K1976024: Due to the fact that the OMT tRNA we tryed to assemble with psB1C3 multiple times had a point mutation, we decided to design the mutagenese primers T_FW-M, T_REV-M-B (for blunt ends) and T_REV-M-S (for sticky ends) and perfomed a mutagenese PCR.

		We met on Tuesday with the whole team.


Lab Week 16: August 1 - August 7		Killswitch BBa_K1976024: Unfortunately our mutagenese experiment ended up in a deletion mutation, so we decided to continue working with the point mutation OMT tRNA.

Both fragments were ligated using the T4‑Ligase by standard protocol. Killswitch Due tot he fact that the OMT tRNA had a point mutation which could not be changed via mutagenese PCR, the orthogonal pair was synthesized by IDT. It was cut with the restriction enzymes EcoRI and PstI, than ligated by standard T4‑Ligation protocol with a psB1C3 or psB1K3 vector which was also cut with EcoRI and PstI but the ligation failed several times.
		Robotics We installed the LEDs, relays and drivers for the LEDs. Sometimes they are not working properly but it seems to be a problem of the software, one is focusing on that task. x-y-Axis and z-axis movement works. We are installing the endstops to assure the steppers motors are stopping at the end of the movement.

We had the attp‑site BBa_11023 flanked by the two additional bidirectional transcription terminators BBa_1001 synthesized by IDT. The attp‑site of BBa_11023 was not the original λ‑attp‑site. Instead the sequence corresponded to the attP2‑site used in the Gateway ® cloning system. The construct was cut with EcoRI and SpeI. The pSB1C3 backbone was cut with EcoRI and PstI. Together with the previously cut BBa_J61002‑BBa_E0240 construct the synthesized BBa_1001‑BBa_11023‑BBa_1001 construct was ligated in the cut pSB1C3.
