Description
During phage display experiments small sequences were found that bind to the polystyrene plastic surfaces of the used microtiter plates. The binding was strong enough to resist several washing steps. The sequence binds to plastic due to its high hydropathy.
Notes
To make the plastic binding domain observable we coupled it to GFP as a reporter. Due to the high hydropathy of the plastic binding sequences this protein seems to be toxic to the bacteria. For this reason we used an inducible promoter for the expression of this part. The cells can be cultivated until an optical density of 60-80 followed by an addition of IPTG to induce the expression of the protein.
