Fluorescence and water dispensation

Differently from the measures of absorbance, we find out that the dispensation of water in the well causes an amplification of the fluorescence signal, both for bacterial coltures and simple liquid growing medium (in figure the results for a colture producing GFP).

This amplification seams to be non linear and characterized by a kind of saturation, if analised on a large scale of volumes.

You can find more informations about the experiment at LINK - Test n.9, 07/07/09.

Fluorescence and diluitions in water

The proportionality between fluorescence measurements (GFP and RFP) and different diluitions of LB was verified in two volumetric diluitions.

This considerations has not to be read together with the results of the non-liner relationship between fluorescence and water dispensation, because even if different amounts of water in the well means different diluition of the colture, in that simulation we didn't work with costant volume in the well, as in this case we do.

The first to measurements must not be taken into account because of the high measure's rumour.
