The emission spectra of all members of the collection were measured in the same plate reader in parallel experiments and the results were normalized by dividing by the OD600 Figure 1. Figure 1: Fluorescence spectrum of E. coli BL21 expressing GFP under five different constitutive promoters, at the excitation wavelength of 488 nm.

The structural similarities and fluorescent distinctions between mCherry and EGFP illustrate an important characteristic of fluorescent proteins: they are easily tunable. Today, researchers have either discovered or created fluorescent proteins that cover almost the entirety of the visible electromagnetic spectrum.

The CD spectrum of DsRed is anomalous in the sense that the major CD band has a clear excitonic character. Far-UV CD spectra of GFP confirmed the presence of the high beta-sheet content of the polypeptide chain in the three-dimensional structure.

If You Dont Know This About GFP, FITC, And PE, You Might Publish False Flow Cytometry Data. When we learn about fluorescence, the first thing we are told is that fluorophores emit photons that are higher wavelength than the photons that they absorb. What this specifically refers to is the stokes shift, which results from non-radiative energy transfer during the fluorescence process. When a photon is absorbed by a fluorophore molecule, some of the resultant energy is lost in molecular vibration and movement among other things so that the energy released after fluorescence is lower than the energy absorbed. Since wavelength is inversely proportional to energy, this lower output energy light is higher in wavelength than the input light. It is important to examine a fluorophore in terms of its excitation and emission spectra, which essentially indicate the probability that a molecule will emit a photon of a certain wavelength of light given an excitation photon of a given wavelength. Figure 1 below illustrates the excitation and emission spectra of FITC under conditions of 488 nm excitation.

DsRed can be used as a expressible fluorescent reporter system in a manner similar to Green Fluorescence Protein GFP. Its unique excitation/emission characteristics allow it to be used simultaneously with GFP and YFP using 488 nm excitation, and with GFP/YFP/CFP using dual 457 nm/568 nm excitation Beavis and Kalejta, 1999; Hawley et al, 2001. Excitation and emission spectrum for ECFP, EGFP, EYFP and DsRed blue, green, yellow and red traces, respectively.
