Labjournal 2016
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 advisors offered classes like a snapgene workshop (March 4), how to use scifinder (March 12) and a cloning strategies workshop (March 17).

Metabolic burdenPromoter test (J23109, J23101 and J23115):pSB3K3‑BBa_E0240 was cut with the restriction enzymesXbaI and PstI. J61002 with the promoter J23109, J23101 or J23115 was each cut with SpeI and PstI and then ligated with the cut BBa_E0240 construct. The ligation product was transformed into E. coli Top 10 via heatshock. The strength of the three promoters was then compared by observing the fluorescence of the GFP. |

The ordered materials arrived and we started assembling the chassis. We talked to the workshop and they prepare some of the parts for us. One of our team members is preparing the OpenCV software and getting familiar with the camera | |

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 | |

miniColicinThe 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 EcoR1 and Pst1. 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. |

Mounted the z-axis and tuned the x-y axis. The optical software is nearly ready to use and we like to test it next week. We started connecting the electronics to an ATX power supply. The Raspberry Pi is set up and ready to use. We still have some problems with the wireless connection. | |

Our team team visited Evonik and was granted the opportunity to see how they work. |
Lab Week 22: |

Reporter SystemBBa_K1976003:The mVenus-LVA-pSB1C3 plasmid was cut with EcoRI and PstI and ligated into a T7-RBS-pSB1A3 plasmid which was cut with SpeI and PstI. Metabolic burdenBBa_K1976000:The BioBrick BBa_E0240 was cut with the restriction enzymes XbaI and PstI. BBa_J61002 was cut with SpeI and PstI. The two restriction products were ligated by standard T4‑Ligation protocol. BBa_K1976001: B0034‑BBa_I11020 was cut with XbaI and PstI. BBa_J23101 was cut with SpeI and PstI. Both fragments were ligated using the T4‑Ligase by standard protocol. |

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. | |

Reporter SystemBBa_K1976003:The ligation product was transformed into E.coli Top 10 by heat shock transformation and the cells were spread out on a Ampicillin agar plate. Metabolic burdenBBa_K1976000:After plasmid preparation, the plasmid was cut with XbaI and PstI. 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. BBa_K1976001: The ligation product was transformed into E. coli Top 10 via heatshock. |
