Beschreibung: Green fluorescence protein (GFP) is a 27 KDa protein derived from the bioluminiscentjellyfish Aquorea victoria, emiting green light ( λ =509 nm) when excited (excitation by Blue or UV light, absorption peak λ =395 nm). GFP is a useful tool in cell biology research, as its intrinsic fluorescence can be visualized inliving cells. Light-stimulated GFP fluorescence is species-independent and a fluorescencehas been reported from many different types of GFP-expressing hosts, including microbes,invertebrates, vertebrates and plants. No exogenous substrates and cofactors are requiredfor the fluorescence of GFP, since GFP autocatalytically forms a fluorescent pigment fromnatural amino acids present in the nascent protein.GFP fluorescence is stable under fixation conditions and suitable for a variety ofapplications. GFP is widely used as a reporter (tag) for gene expression, enablingresearchers to visualize and localize GFP-tagged proteins within living cells without anyfurther staining. Other applications of GFP include measurement of distance betweenproteins through fluorescence energy transfer (FRET) protocols. To increase a fluorescenceintensity of GFP, chomophore mutations have been created. The EnhancedGFP has afluorescence 35 times more intense than the wt-GFP. Mutagenesis of GFP has producedalso many mutants (e.g. Yellow Fluorescent Protein, Cyan Fluorescent Protein) with waryingspectral properties. Antibodies raised against full-length GFP variants should also detectother variants of the protein.

Spezifität: The polyclonal antibody recognizes GFP, EGFP, EYFP fusion proteins in all species.
