gfp excitation
In fact, one of the most important features of EGFP and wt-GFP is that these proteins do not require ligands to fluoresce. The success of wt-GFP and EGFP as reporters in the field of cell biology led researchers to search for more fluorescent proteins with different excitation and emission spectra. Of the fluorescent proteins found, DsRed PDB: 1G7K from the sea anemone Discosoma was especially valuable because its red-shifted fluorescence was quite visually distinct from that of GFP.

Characterization of Excitation and Emission Spectra of Commonly Used Variants of Green Fluorescent Proteins.
A suitable filter set must be used for the GFP variant being determined. Using the standard fluorescein filter set, i530/25 emission and 485/20 excitation when quantitating wtGFP leads to a signal loss of 20% in comparison to the proposed 508/20 emission and 400/30 excitation filter set, as shown in Figure 2B.

La GFP a été découverte en 1962, par le chercheur Osamu Shimomura et ses collaborateurs, aux laboratoires Friday Harbor de lUniversité de Washington, quand ils étudiaient la bioluminescence de la méduse Aequorea victoria, un cnidaire présent dans lOcéan Pacifique au large de lAmérique du Nord.

Two-Photon Activation and Excitation Properties of PA-GFP in the 720920-nm Region ScienceDirect. ScienceDirect.
This report covers the two-photon activation and excitation properties of the PA-GFP, a photoactivatable variant of the Aequorea victoria green fluorescent protein in the spectral region from 720 to 920 nm. It is known from this special form of the molecule that it has an increased level of fluorescence emission when excited at 488 nm after irradiation at 413 nm, under single-photon excitation conditions.

Dear Madam/Sir I want to perform some preliminary fluorescence tests for a project of ours. I am interested in buying one of the following emission filters MF525-39: GFP MF530-43: FITC I noticed from your records that the outer diameter of the filter is 25 mm.

That is, EGFP protein that is excited with photons at 488nm will give its maximum emission intensity at its emission maximum, 509nm. However, we must remember that this is the maximum emission. The emission spectra is much wider, and for GFP it goes from 470nm up to 630nm.
