  • The uptake was stopped at 15 min. by the addition of 2 ml of ice-cold stop buffer (100 mM KCl, 100 mM mannitol, 10 mM potassium phosphate, pH 7.4) and the mitochondria were collected by rapid filtration on 0.45 μM Millipore membrane filters.

  • Mice were fed NIH31 (6 % fat) chow ad libitum, and their water was acidified to pH 2.8 to 3.2.

  • Single stranded phage DNA was prepared from phage particle suspension with phenol extraction [ 54 ] . Phenol was tris-equilibrated at pH 8.0 (Sigma).

  • Each PCR included 2 μl of the RT reaction containing the primary strand cDNA, reaction buffer [10 mM Tris-HCl (pH 8.4), 50 mM KC1, 1.5 mM MgCl 2 , 0.001% gelatin], 2 μM of each dNTP, 0.2 μM of the same anchored primer used in the RT reaction, 0.2 μM of one of the eight 13-mer arbitrary primers API-8 (Table 1), 12.

  • The concept that fluoride protects better from caries in a low pH environment [ 12 ] was recently used to explain why there is a poor association between caries experience and pH fall after a 10% sucrose rinse [ 33 ] . In low responders, increased fluoride exposure from dentriflce use to maintain oral health, or from water fluoridation, associate relatively poorly with caries experience.
