RelevanceFunction: Energy-transfer acceptor. Its role is to transduce the blue chemiluminescence of the protein aequorin into green fluorescent light by energy transfer. Fluoresces in vivo upon receiving energy from the Ca2+ -activated photoprotein aequorin.
Subunit structure: Monomer.
Tissue specificity: Photocytes.
Post-translational modification: Contains a chromophore consisting of modified amino acid residues. The chromophore is formed by autocatalytic backbone condensation between Ser-65 and Gly-67, and oxidation of Tyr-66 to didehydrotyrosine. Maturation of the chromophore requires nothing other than molecular oxygen.
Biotechnological use: Green fluorescent protein has been engineered to produce a vast number of variously colored mutants, fusion proteins, and biosensors. Fluorescent proteins and its mutated allelic forms, blue, cyan and yellow have become a useful and ubiquitous tool for making chimeric proteins, where they function as a fluorescent protein tag. Typically they tolerate N- and C-terminal fusion to a broad variety of proteins. They have been expressed in most known cell types and are used as a noninvasive fluorescent marker in living cells and organisms. They enable a wide range of applications where they have functioned as a cell lineage tracer, reporter of gene expression, or as a measure of protein-protein interactions. Can also be used as a molecular thermometer, allowing accurate temperature measurements in fluids. The measurement process relies on the detection of the blinking of GFP using fluorescence correlation spectroscopy.
Sequence similarities: Belongs to the GFP family.
Biophysicochemical properties: Absorption: Abs(max)=395 nm
Exhibits a smaller absorbance peak at 470 nm. The fluorescence emission spectrum peaks at 509 nm with a shoulder at 540 nm.

Additional bands at: 28 kDa. We are unsure as to the identity of these extra bands.
ab6658 staining GFP in human melanoma cells recovered from nude mice by Immunocytochemistry/ immunoflurescence. Cells were fixed with formaldehyde, permeabilized with 0.25% Triton X-100 RT for 10min and blocking with commercially available blocking buffer was performed for 30 minutes at RT. Samples were incubated with primary antibody (1:50) for 18 hours at 4°C. An Alexa Fluor®488-conjugated donkey polyclonal to goat IgG was used as secondary antibody at 1/100 dilution. Green color indicates GFP/Fibrolast cells, while red color indicates Ki67 positive cells, most of them are tumor cells (Abcam`s ab15580 was used for the detection).
Immunofluorescence Microscopy using ab6658. Tissue: Drosophila melanogaster late stage embryonic central nervous system. Fixation: 0.5% PFA. Antigen retrieval: not required. Primary antibody: Anti-GFP antibody at a 1/1,000 for 1 h at RT. Secondary antibody: AlexaFluor 488™ conjugated anti-Goat antibody at 1/300 for 45 min at RT. Panel A: shows a lateral view (ventral left). Panels B and C: shows ventral views of whole mount embryos at 63x magnification (plus 2x digital zoom). In all panels, anterior is up. Staining: tau-GFP cell bodies (large arrowhead) and axons of motorneurons (arrow) and interneurons (small arrowhead) as green fluorescent signal.
Immunofluorescence Microscopy using ab6658. Tissue: Sf-1:Cre mice crossed to the Z/EG reporter line. Mouse brain (coronal view, 20X magnification). Fixation: 4%PFA/PBS with o/n fixation, and subsequently transferred to a 30% sucrose solution. Antigen retrieval: frozen in OCT freezing medium (Sakura) and cryostat sectioned at 40 microns. Primary antibody: Goat anti- GFP was used at 1/500 dilution in free floating imunnohistochemistry to detect GFP. Secondary antibody: Fluorchrome conjugated Anti-goat IgG secondary antibody was used for detection at 1:10,000 for 45 min at RT.Localization: Sf-1+ neurons and their processes of the ventromedial nucleus of the hypothalamus. Staining: eGFP as green fluorescent signal and sections were counterstained with DAPI.
ab6658 staining GFP in rat brain cells infected with viruses containing GFP under a CMV promoter by Immunocytochemistry/ Immunofluorescence.Cells were fixed with formaldehyde, permeabilized using 0.2% Triton, blocked with 20% serum and then incubated with ab6658 at a 1:50 dilution for 20 hours at 25°C. The secondary used was an Alexa-Fluor 488 conjugated rabbit polyclonal, used at a 1/200 dilution.
