Nadh molar extinction coefficient
WitrynaDetermine the extinction coefficient (molar absorptivity) of hemoglobin solution knowing that its absorbance of 1.18 \times 10^{-6} M solution is 0.45. The path length is 1 cm. Data has been collected to show that at a given wavelength in a 1.00 cm pathlength cell, Beer's Law for the absorbance of Co2+ is linear. WitrynaThe activity of lactate dehydrogenase can be measured by monitoring the following reaction: Pyruvate + NADH → Lactate + NAD+ The molar extinction coefficient of NADH at 340 nm is 6220 M –1.cm –1. NAD+ does not absorb at this wavelength. In an assay, 25 µL of a sample of enzyme (containing 5 µg protein per mL) was added to a …
