Protein Quantification A280. The absolute values of the slopes were taken as surrogates for LDH activity of the samples (in a unit of μM/min/ml). Absorbance data are collected using a SPECTRAmax 250 microplate spectrophotometer equipped with SOFTmax PRO software . The extinction coefficient for NADH is 6220 M^-1 cm^-1 at 340 nm. Serial dilutions of NADH and NAD+ ranging from 0-500 µg/ml were made using TE pH 8.0 aqueous buffer a s the diluent. Solution for A 0.800 ml aqueous solution of NADH shows an absorbance at 340 nm of A = 0.333. nadh absorbance at 340 nm. Wiki User. Convert μM into M. 1 μM = 10⁻⁶ M; 10 μM = 10 × 10⁻⁶M = 10⁻⁵ M ; Path length, L = 1 cm python cache class. . NADH Analysis - ms-bioanalytical Recoveries from the standard addition experiments are consistent with the metabolite recovery efficiency data shown in Table 2. The Vitros application is … 0 GSSG + NADPH + H + GR 2GSH + NADP → + Equation 3 The oxidation of NADPH to NADP + is accompanied by a decrease in absorbance at 340 nm (A340) providing a spectrophotometric means for monitoring GPx enzyme activity. Furthermore, the characteristic absorbance of NADH at 340 nm in the UV-Vis spectrum was imperceptible (fig.
