The iGEM InterLab Study is the currently the largest interlaboratory study in synthetic biology [refs]. The interlab study investigates the replicability of data by providing all participating iGEM teams with protocols for measuring the fluorescence output of a set of genetic devices that have been designed to provide varying levels of Green Fluorescent Protein (GFP) expression. Team Newcastle 2017 followed the Interlab plate reader protocol, which can be found here (link protocol document). This year, teams were provided with the InterLab Measurement Kit containing fluorescein and LUDOX stocks, along with the devices stored in the Distribution kits. The devices are: - A positive control: BBa_I20270 - A negative control: BBa_R0040 - Test Device 1: BBa_J36000 (J23101.BCD2.E0040.B0015) - Test Device 2: BBa_J36001 (J23106.BCD2.E0040.B0015) - Test Device 3: BBa_J36002 (J23117.BCD2.E0040.B0015) - Test Device 4: BBa_J36003 (J23101+I13504) - Test Device 5: BBa_J36004 (J23106+I13504) - Test Device 6: BBa_J36005 (J23117+I13504) OD600 Reference PointLUDOX-HS40 was used as a single point reference to obtain a radiometric conversion factor to convert absorbance data into a standard OD600 measurement. The Reference OD600 divided by the Abs600 from four replicates of LUDOX was used to obtain a correction factor for use against the cell based assays. Fluorescein Standard CurveA dilution series of fluorescein in four replicates was prepared and measured in the plate reader to obtain a standard curve of fluorescence for fluorescein concentration. This was used to correct cell-based readings to an equivalent fluorescein concentration, and to then convert this to a GFP concentration. Plate ReaderCompetent E. coli DH5α cells were transformed with each of the devices and plated onto LB+Chl agar, and two colonies from each transformation plate were grown overnight in 10 ml LB + Chl in 50 ml Falcon tubes. Protocols for making competent cells and cell transformation can be found here (link to protocol). Fluorescence was measured as specified in the InterLab protocol on a Synergy H1 plate reader. |
