Figure 10. Relations between pH and (A) calcium and magnesium concentrations, and the saturation index for calcite, and (B) phosphate concentration. The solid and open symbols represent samples collected during the first (8/30/00) and second (5/30/01) cycling experiments, respectively.

Primer optimization of magnesium concentration and temperature should be carried out in advance for new assays. Ideally a gradient PCR with different magnesium concentrations should be performed, if a thermocycler with a gradient block is available. If a pre-made PCR mix is used, only temperature optimization need be performed (see Note 10). An example gradient set-up based on a 96-well PCR block with gradient function follows ... 

T. aquaticus and catalyzes the primer-dependent incorporation of nucleotides into duplex DNA in the 5 3 direction in the presence of Mg. The enz3mie does not possess 3 5 exonuclease activity but has a 5 3 exonuclease activity. The Taq DNA polymerase is isolated from T. aquaticus and suitable for most PCR amphfica-tions that do not require a specific high-fidelity enzyme, such as the detection of specific DNA or RNA sequences. However, the error rate of Taq DNA pol3mierase is approximately 1 x 10 errors/base and also depends on the reaction conditions. The fidelity is slightly higher at lower pH, lower magnesium concentration, and relatively low dNTP concentration (Eckert and Kunkel, 1990, 1991).

The solubility of calcium phosphate depends on the type of amino acid product used, the type of calcium and phosphate salts used, temperature, magnesium concentration, and the final volume of the admixture. The pH of the parenteral nutrition admixture influences the equilibrium between the trivalent phosphate ion and its monobasic (H2P04 ) and dibasic (HP04 ) forms. The aqueous solubility of the monobasic and dibasic calcium phosphate amounts to 18 g/L and 0.3 g/L, respectively. At the physiological pH of 7.4 about 60 % of the phosphate exists in the poorly soluble dibasic form. If the pH of the nutrition admixture is lower than pH 6.4, the monobasic form is the predominant one and the chance of precipitation is diminished (see Sect. 18.1.1).
