The spectrum represents the average absorption spectra of all peaks shown in the HPLC chromatogram in panel B. Using a molecular weight of 652 for the acetate salt, we measured molar extinction coefficients of: ε330nm=25,094 M−1cm−1 and ε425nm=15,146 M−1cm−1 in ethanol.
Concentrations were calculated on the basis of a molecular extinction factor at 450 nm of 134,000 l · mol−1 · cm−1.
We use a molecular phylogeny with gene and species trees and diversification rate analyses to investigate how environmental change has affected speciation and extinction rates in the genus Sternopriscus.
Instead, they used a "molecular clock".
Such reactors can run on non-enriched uranium as fuel and uses a molecular variant of water as a coolant.
The concentration of the different TIMs was determined from their absorbance at 280 nm using the molecular extinction coefficients (є280) of 34950 M−1 cm−1 for TbTIM, 33460 M−1 cm−1 for TcTIM, 36440 M−1 cm−1 for LmTIM, 26664 M−1 cm−1 for ScTIM, and 42925 M−1 cm−1 for BSA.
The monomeric anthocyanins content was expressed as mg per 100 g fresh bilberries, respectively jam using a molar extinction coefficient of 26 900 and a molecular weight of 449.2 of the most prevalent anthocyanin (usually cyanidin-3-glucoside).
Pigment content was calculated as milligrams cyanidin-3-glucoside per 100 g fresh fruit or jam using a molar extinction coefficient of 26 900 L/cm/mol and molecular weight of cyanidin-3-glucoside (449.2 g/mol).
The concentration of eGFP in the lysate from the H-4 cell population was measured by spectrophotometry at a wavelength of 488 nm using a molar extinction coefficient of 55,000 M−1 · cm−1 and an eGFP molecular weight of 32.7 kDa [ 15].
