8 Yazawa DuPont-NEN and the molar concentration of it is calculated from the specification data shipped with the radionuclide. 12. <strong>Protein</strong> solution: Contaminating Ca 2+ in the protein solution should be reduced to less than 0.1 mol/mol of the total Ca 2+ -binding sites in the initial sample solution. Several methods have been reported to reduce the contaminating Ca 2+ in the neutral pH such as addition of 50–100 mM EDTA or ethyleneglycol-bis (2-aminoethyl ether)-N,N,N',N'-tetraacetic acid (EGTA) (optionally in the presence of 6 M urea) followed by passage through a Sephadex G-25 desalting column (12), and extensive dialysis against or column chromatography with Chelex-100 chelating resin (2). For stable proteins such as calmodulin, troponin C, and parvalbumin, addition of trichloroacetic acid to 3% precipitates Ca 2+ -free proteins, which can be renatured by neutralization (6,13). Precipitates were collected by centrifugation, homogenized with addition of small volume of deionized water, and dissolved with addition of small volume of 2 M Tris base, which is followed by passage through a Sephadex G-25 column. The concentration of contaminating Ca 2+ in the protein solution is determined by atomic absorption spectrometry, and is taken into account in the calculation of the Ca 2+ -binding data. <strong>Protein</strong> concentrations must be determined with a suitable and reliable method, such as quantitative amino acid analysis or UV spectro-photometric determination. 3. Methods The following procedures, except for the final calculation step, as well as the dilution of 45 Ca 2+ aforementioned, are to be carried out in a room equipped with facilities necessary for handling of radioisotopes. 3.1. Assembly of the Flow-Dialysis Cell When everything is ready to begin, the flow-dialysis cell, which has been stored as disassembled parts, is assembled with mounting a dialysis membrane (see Fig. 3) (see Note 6). 1. Immerse the degassed buffer solution in the 500 mL Erlenmeyer flask in the water bath and equilibrate at 25°C. 2. Fill a disposable plastic syringe (5 mL) with the buffer solution and, after removal of air bubbles, connect it to the PE tube (inlet) of the buffer chamber of the dialysis cell. 3. Fill the buffer chamber with the buffer solution sent from the syringe through the PE tube. 4. Fill the other PE tube (outlet) with the buffer solution from the chamber by sucking with another syringe connected to the other end of PE tube. 5. Put a magnetic stirring bar (discoid, 1 cm in diameter) into the chamber, and fill the chamber with the buffer solution.
