WebMar 31, 1998 · Therefore, we have determined the reactivity of T toward DTNB as a function of increasing concentration of zinc. Remarkably, there is a linear decrease of the extent of DTNB reduction to 10% of its original value until four equivalents of zinc are added to T (Fig. 6). The remaining reactivity upon adding more zinc corresponds to that of MT at ... WebDTNB is soluble in ethanol at 8 mg/mL, giving a clear yellow to yellow-green solutions. However, approximately 5 mM DTNB can be made in about a 100 mM sodium or potassium phosphate buffer solution, pH 7.2 containing 0.1 mM EDTA. (This should be stable for greater than 2 months if stored in the dark between 0-5°C, possibly up to 6 months.)
