title: Determination of the specific activity of NaB3H4.
abstract: A method for the rapid determination of the specific activity of NaB3H4 is presented. NaB3H4 is used to reduce NAD+ to [3H]NADH, which is then isolated by anion exchange chromatography. The specific activity of the NaB3H4 is calculated from measurements of radioactivity and absorbance (340 nm) in the [3H]NADH fractions.
