Fitc extinction coefficient
WebMeasure the absorbance of the fluorophore at the wavelength of maximal excitation (e.g. for FITC use 495 nm wavelength). Divide this value by the molar extinction coefficient for the dye. ( e.g. FITC has an extinction coefficient of 75,000 M-1 cm-1). Determine the labeling. Divide the fluorophore concentration, determined in step 2, by the ... WebNov 14, 2014 · The extinction coefficient is known for the excitation maximum (Table 1) and students have measured or looked up the excitation spectra of the standards and fluorescent proteins. The extinction coefficient for the wavelength to be used in quantum yield experiments was estimated as follows: A ratio was measured by dividing the …
