WebThe distribution of GFP intensity and the cell number can be presented in a histogram format as flow cytometry (Fig 4). The graphs of a control and a sample are plotted, and the threshold is determined automatically. Users can manually change the threshold, and the percentage of GFP positive and negative cells will be reflected accordingly.

The GFP from A. victoria has a major excitation peak at a wavelength of 395 nm and a minor one at 475 nm. Its emission peak is at 509 nm, which is in the lower green portion of the visible spectrum. The fluorescence quantum yield (QY) of GFP is 0.79. The GFP from the sea pansy ( Renilla reniformis) has a single … See more The green fluorescent protein (GFP) is a protein that exhibits bright green fluorescence when exposed to light in the blue to ultraviolet range. The label GFP traditionally refers to the protein first isolated from the See more The purpose of both the (primary) bioluminescence (from aequorin's action on luciferin) and the (secondary) fluorescence of GFP in jellyfish is unknown. GFP is co-expressed with aequorin in small granules around the rim of the jellyfish bell.
