For example, the GFP-Trap recognizes AcGFP, Clover, eGFP, Emerald, GFP, GFP5, GFP Envy, GFP, S65T, mGFP, mPhluorin, PA-GFP, Superfolder GFP, TagGFP, TagGFP2, monomeric eGFP K206A, CFP, YFP, Citrine, eCitrine, eYFP, Venus, Ypet, BFP (click here for a complete list). Most GFP antibodies also recognize other derivatives, especially if there are just a few amino acid substitutions compared to GFP or EGFP.

The chromophore, actually a two-ring chromophore, of GFP lies in the center of a beta-barrel structure. The two-ring chromophore of GFP absorbs and emits light, e.g., light photons, in the visible green spectrum. Left: beta-barrel structure and fluorescent core of enhanced GFP (EGFP), a GFP derivate right: magnification of the fluorescent core, the two-ring chromophore These acids and the cyclization and oxidation of their backbone form a two-ring chromophore. In the center of this β-barrel, there are 3 amino acids. GFP and GFP derivate EGFP have a β-barrel structure. victoria has a major excitation peak at a wavelength of 395 nm and a minor one at 475 nm. GFP emission spectrum and excitation peaks GFP-tagged proteins are often used for fluorescence microscopy, immunoprecipitation, protein purification, and Western blotting.ĥ. Proteins fused to GFP are called GFP-tagged proteins or GFP-fusion proteins. Tagged proteins can be used for purposes such as immunoprecipitation, microscopy, protein purification, Western blotting, protein arrays, etc. One solution that enables easy detection is to genetically fuse protein and peptide tags to the protein of interest. What are GFP-tagged proteins and GFP-fusion proteinsĮndogenous proteins do not contain protein or peptide tags and therefore are sometimes difficult to detect in an assay. What are GFP-tagged proteins and GFP-fusion proteins.Ĥ. This has actually made lots of new experiments possible.4. This property has had an enormous impact on cell biology: GFP and proteins fused to GFP can be detected as GFP works as a fluorescent tag. If excited by light in the ultra-violet or blue spectrum, GFP emits green light (for more details please see sections 8 and 9). 
Once GFP is expressed and properly folded, it shows fluorescent properties. GFP is a protein and, like other proteins, it can be expressed by living organisms. In 2008, The Nobel Prize in Chemistry was awarded “for the discovery and development of the green fluorescent protein, GFP.” See Roger Tsien’s Nobel Prize lecture here. Roger Tsien’s lab improved GFP and managed to convert it into a commonly used research tool. In 1992, the sequence of GFP was cloned (Douglas Prasher) and Martin Chalfie’s lab expressed the sequence in vivo. It was isolated by Osamu Shimomura in 1962. GFP is an endogenous protein from the jellyfish Aequorea Victoria. This property has had an enormous impact on cell biology by enabling the imaging of almost any protein, in transcription studies by working as a reporter gene, and in biochemical applications. If GFP is exposed to light, it emits a green fluorescent signal. GFP is a fluorescent protein that can be expressed in vivo. GFP stands for green fluorescent protein.
