Assays

The membrane potential of cells grown overnight in a certain concentration of KCl will be determined, to reveal a relation between external KCl and a possibly stable membrane potential. See also "2D-Gel Electrophoresis " Assay for further details.

The pH of cells grown overnight in a certain concentration of KCl will be determined, to reveal a functional relationship between external KCl and a stable pH. See also "2D-Gel Electrophoresis" Assay for further details.

The potassium content of cells grown overnight in a certain amount (0.1, 0.2, 0.5, 1, 5, 20, 50, 200 mM) of KCl will be determined. Additionally the potassium content of cells grown overnight in high potassium and shifted to the amounts of potassium used in the former experiment. After growing overnight again in the lower potassium, the cells should contain finally a comparable potassium concentration than the cells grown in the respecting KCl in the first experiment.

The volume of cells grown overnight in a certain concentration of KCl will be determined, to reveal a relation between the osmotic effects of external KCl and the cell volume. See also 1.4.1. for further details.

Dear SEEK users, this Assay is just an example Excel sheet for intracellular metabolites concentration measurements performed using cell culture growing in chemostat

Steady state concentrations of extracellular metabolites in yeast Saccharomyces cerevisiae in anaerobic chemostat at D = 0.1 h-1 on minimal medium

experimentally measured extracellular fluxes in yeast Saccharomyces cerevisiae in anaerobic glucose limited chemostat (D=0.1 h-1) on minimal medium

The model describes the behaviour of E. coli in a stationary chemostat with different oxygen availability.

Steady state study of the effect of altering gene regulation on yields of end-products, focusing on butanol.

The stressosome is an important sensor of environmental stresses in B. subtilis. It is formed by three protein types that form an icosahedral geometric protein complex. There are uncertanties how protein interactions take place, what the effects on the response behaviour of activation and inhibition of phosphorylation among proteins is, and what kind of proximal signal activates the stressosome in the first place. To answer these questions a computational modelling approach was developed. This ...

Measurements of acetone, butanol, acetate, butyrate and ethanol taken during dynamic shift (pH 5.8, 5.5, 5.3, 5.1, 4.9, 4.7, 4.5) and at steady state (pH 5.7, 5.5, 5.3, 5.1, 4.9, 4.7, 4.5).
