Ligations were transformed into a [http://openwetware.org/wiki/User:Wilfred_J._Poppinga/Notebook/Wilfreds_Project/2009/07/31#Competent_cells new batch] of competent cells and plated out on TY Amp100 plates.

We had a look at ways to measure things concerning gas vesicles (buoyant density, volume, etc.), buoyant density was [http://dx.doi.org/10.1016/0167-7012(92)90048-9 previously measured] using a specific apparatus which we're not likely to obtain. We also talked with some biologists about ways to detect protein concentrations (or rather, amounts) using antibodies, apparently this might be possible if we attach something for which there is a kind of "standard" antibody available (and the maltose binding protein we're attaching to ArsR might qualify as such).
To measure the total arsenic content in the cell you can use coupled mass spectrometry. for more details see Metal accumulation.
