WebAug 31, 2024 · To do this, you calculate the slope of the linear standard curve, which is in units of absorbance change/µM PNp. Divide the initial rate (delta absorbance/min) by the slope of the standard curve (delta absorbance/µM) to get µM/min. This can also be written as µmoles/min/liter, which is also units/L. WebThat is, it is the rate after a burst phase has occurred, and the system has settled into something close to a steady state. That said, measuring initial rates is done for two practical reasons. 1) we can approximate the product concentration as 0. For a reaction that is at all reversible or product-inhibited, the math is much easier if [P]=0.
