Day -1 (Mar 2 Mon)

  <Bioreactor headplate configuation>
   pH sensor: monitor or control pH
   dO2 sensor: monitor or control dO2
   Condenser: Gas outlet
   OD probe: monitor cell growth ==> Not used! Replate it with septum

  1. Peamiability test: Aliquots (100 µl) of this cell suspension were pipetted into fluoroplate wells, 
     which contained NPN (10 µM) and, as test substances, either EDTA (1.0 and 0.1 mM), PEI (10 µg ml–1), 
     DMSA (1 mM), AOT (1 mM), or HEPES buffer (control) to make up a total volume of 200 µl. If desired, 
     MgCl2 was added to the cell suspension before addition of NPN. Fluorescence was monitored within 
     3 min from four parallel wells per sample (excitation, 355 nm; half bandwidth, 38 ± 3 nm; emission, 
     402 nm; half bandwidth, 50 ± 5 nm). Each assay was performed at least three times.
