背景介绍 Green fluorescent protein (GFP) is a 27 kDa protein derived from the jellyfish Aequorea victoria, which emits green light (emission peak at a wavelength of 509 nm) when excited by blue light (excitation peak at a wavelength of 395 nm). 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 technology 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. 产品介绍 Affinity purified Anti-GFP (Green Fluorescent Protein) Tag clone GF28R, mouse IgG1. Recognizes native and denatured forms of GFP and its variants such as: EGFP, YFP, EYFP, and CFP. Applications: Western Blot(1:1000-3000), Dot Blot, ELISA, Immunocytochemistry(1:500-2000), Immunoprecipitation. Optimal dilutions/concentrations should be determined by the end user.
