NOTEBOOK

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).

Lab Week 1:

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.

Decision who will participate in the project and which direction we chose. 4 people form the team and we do some research. Idea is to redesign a 3D printer

We went to the local Weinlagenwanderung to get out, drink some quality wine and enjoy some great views.

Lab Week 3:
May 2 - May 8

This week, we organised the lab work before the actual work started.

Robotics
Meeting and making a team commitment

The BBa_K1976048 was made by performing a PCR on a product synthesized by IDT, using the primers prefix right and suffix rightand 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. Lastly E. Coli Top10 have been transformed with the ligation.

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 will built a lightbox wit IR LEDs. To assure a homogeneous IR light we will use a diffuser plate illuminated from the sides. One team member prepares the technical drawing.

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.

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 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.
