The first team meeting was on 18.3.2016, where we discussed <a href="https://2016.igem.org/Team:Slovenia/Notebook/Proposals" >initial project proposals</a> from students accepted to the team.

Our team spent time going through literature and got together many times to brainstorm and discuss ideas. Eventually we settled on the final idea. We discussed plasmids, chemicals and cell lines already present in the Department of Synthetic Biology and Immunology, National Institute of Chemistry (Slovenia), where we spent most of these six months, performing our experiments.

Before 25.4.2016

The first team meeting was on 18.3.2016, where we discussed initial project proposals from students accepted to the team.

Our team spent time going through literature and got together many times to brainstorm and discuss ideas. Eventually we settled on the final idea. We discussed plasmids, chemicals and cell lines already present in the Department of Synthetic Biology and Immunology, National Institute of Chemistry (Slovenia), where we spent most of these six months, performing our experiments.

  25.4.2016 - 1.5.2016

Cloning :

  • rapamycin constructs inducible split TEV protease (Nik, Tjaša)
  • constructs with iRFP for retrieval in and on endoplasmic reticulum (ER) (Nik, Tjaša)
  • mechanosensitive channels and gas vesicles (GvpA and GvpC) (Estera,Rok)

  2.5.2016 - 8.5.2016

Testing GvpA and GvpC:

  • expression in HEK293T cell line (Estera)
  • cytotoxicity in HEK293T cell line (Rok)

  9.5.2016 - 15.5.2016

Cloning of:

  • new constructs of mechanosensitive channels and gas vesicles with coiled coil peptides (Estera, Rok)
  • light inducible systems with split firefly luciferase (Nina)
  • constructs for firefly luciferase with inducible reconstitution in ER via inteins (Nik)
  • wild type TEV protease (Arne)
  • TEV protease reporters (for wt TEV substrate, E and H variant) (Arne)
  • split firefly luciferase constructs with coiled coil peptides (Katja)
  • single chain calcium sensing constructs (CaMgaroo-2, SaVe2.12 and SaVe6.1) (Katja)

Testing:

  • GvpA and Gvp expression in in HEK293T cell line with western blot and immunostaining (Estera)
  • ratio optimization and localization with confocal microscopy (Estera)
  • repeating cytotoxicity test in HEK293T cell line (Rok)
  • testing construct in or on ER
  • retrieval of iRFP:P3:GCN:P4:KDEL construct in ER with confocal microscopy and western blot (Nik, Tjaša)
  • inducible release of from ER with confocal microscopy and western blot and immunostaining (Nik, Tjaša)

  16.5.2016 - 22.5.2016

Cloning:

  • cloning new constructs of mechanosensitive channels and gas vesicles with coiled coil peptides (Estera, Rok)
  • light inducible systems with split luciferase (Nina)
  • variant of TEV protease active in ER (Nik)
  • FRET based TEV protease sensors (Arne)
  • single chain calcium sensing constructs (CaMgaroo-2, SaVe2.12 and SaVe6.1) (Katja)
  • permuted firefly luciferase reporter for TEV and PPV protease (Tjaša)

Testing:

  • split firefly luciferase reconstitution via coiled coil interaction with dual luciferase assay (Katja)

Repeating:

  • testing GvpA and GvpC expression in in HEK293T cell line with western blot and immunostaining (Estera)

  23.5.2016 - 29.5.2016

Cloning:

  • cloning new constructs of mechanosensitive channels and gas vesicles with coiled coil peptides (Estera, Rok)
  • light inducible systems with split luciferase (Nina)
  • single chain calcium sensing constructs (CaMgaroo-2, SaVe2.12 and SaVe6.1) (Katja)

Testing:

  • retention on ER and cleavage with recombinant TEV protease - western blot and immunostaining (Nik)
  • localization of modified mechanosensitive channels and gas vesicles in HEK293T cell line with confocal microscopy (Estera)
  • preparation of lipid microbubbles (Rok)
  • of wild type TEV protease activity and orthogonality with the reporters with different TEV substrates (for wt TEV substrate, E and H variant)

Repeating:

  • split firefly luciferase reconstitution via coiled coil interaction with dual luciferase assay (Katja)

  30.5.2016 - 5.6.2016

Cloning:
