<h1>InterLab Study</h1> | <h1>InterLab Study</h1> | ||
− | <p> | + | <p>This year, The iGEM Foundation invited us to participate in the <a href="https://2015.igem.org/Tracks/Measurement/Interlab_study">Interlab Study</a> and we agreed to take part in it. In the study, iGEM teams gather fluorescence data for three GFP expressing devices around the world using the same methods for cloning and measurements. The goal of this international experiment is to find out, how precisely organisms act the same in the different parts of the world if they contain similar genetic material. Our InterLab Study Lab Book can be found <a href="https://2015.igem.org/Team:Aalto-Helsinki/InterLabBook">here</a> for a fully detailed overview of our study.</p> |

Incubated plates overnight (18-20 hours) at 37\(^\circ\)C. Picked up biological triplates from the plates and inoculated 3 ml liquid cultures from the colonies with 12 ml polypropylene test tubes. Incubated the tubes at 37\(^\circ\)C with shaking at 300rpm for 18 hours. Measured OD600 values of cultures in cuvettes and calculated the dilution required for each sample to obtain the OD value of 0.5. Diluted and re-measured the samples to reach 5% accuracy of 0.5. Transfered 200 μl of each sample into 96-well transparent plate and set the platereader to read fluorescence intensity.

The incubation may have generated too much fluorescent proteins even though the samples were diluted properly. The problem wasn't solved after new dilutions of 9:10 ratio and due to the time limit, other ratios weren't attempted. The first blank value is with antibiotics and the second without for the negative control without any plasmids.</p> |

+ | <p>The gel electrophoresis mapping of J23101 + I13504 and J23106 + I13504 can be seen in Figure 1 where the outermost bands belong to ladders. Both the samples (in the middle) should have the same size (2989 bp). The bands belonging to constructs seem to be slightly bigger (~3000 bp) than expected but it is hard to say if the ladders have a bit of inaccuraty. </br></br></p> | ||
