Anti-Green Fluorescent Protein (GFP)

Green Fluorescent Protein (GFP) is a 27kD protein derived from the jellyfish Aquorea victoria, which emits green light (emission peak at a wavelenth of 509nm) when excited by blue light (excitation peak at a wavelenth of 395nm). Green Fluorescent Protein (GFP) has become an invaluable tool in cell biology research, since its intrinsic fluorescence can be visualized in living cells. GFP fluorescence is stable under fixation conditions and suitable for a variety of applications. GFP has been widely used as a reporter for gene expression, enabling researchers to visualize and localize GFP-tagged proteins within living cells without the need for chemical staining. Other applications of GFP include assessment of protein-protein interactions through the yeast two hybrid system and measurement of distance between proteins through fluorescence energy transfer (FRET) protocols. GFP technnology has considerably contributed to a greater understanding of cellular physiology. YFP differs from GFP due to a mutation at T203Y, antibodies raised against full-length GFP should also detect YFP and other variants. Applications: Suitable for use in ELISA, Western Blot, Flow Cytometry, Immunofluorescence/Immunocytochemistry, Immunoprecipitation and Immunohistochemistry. Other applications not tested.
