They have
been determined as mean of six experiments on Serva IPG
BlueStrip, 24 cm, pH 4–7. This ideal grid was used to correct
the experimental spot locations in gels as shown
exemplarily in the false colour image (gel II-b of all six
experiments supplied in Data in brief[10]Fig. 5, 50g
E. coli– red, 0.72g reference grid mixture per well – green).
For details on the protein mix (double spot formation for
trypsin inhibitor) see Ref.[2,4]. (For interpretation of the
references to colour in this figure legend, the reader is
