mRFP Quantification

Several cultures carrying a plasmid that encodes GFP under an arsenite sensitive promoter ([http://parts.igem.org/Part:Bba_K1106004 Bba_K1106004]) were grown overnight with different arsenite concentration (0, 10,..pp Fluorescence was measured with a fluorimeter at 555nm exiitation wavelength and 55nm emission wavelegth. All these data was normalized by the culture density measured by OD.
