Cy5) has proven well. LacZ or Fluorescent Proteins) under the control of a promoter element can be used to quickly determine whether or not a particular protein can activate expression from that element. First identified in 1962in sea creatures, fluorescent proteins have proved versatile and extremely useful, as demonstrated by applications they either enable or significantly benefit. Despite this advance, no fluorescent proteins have been identified from vertebrates, nor has chromogenic ligand-inducible activation or clinical utility been demonstrated. The original green fluorescent protein (GFP) was cloned in 1992 (Prasher et al., Gene, 1992), and since then scientists have engineered numerous GFP-variants and non-GFP proteins that result in a diverse set of colors.Addgene has assembled a collection of empty plasmid backbones with different .

The green fluorescent protein converts this light to green light, which is what we actually see when the jellyfish lights up. Genetically encoded fluorescent protein (FP) tags have revolutionized the analysis of intracellular dynamics and are now the most commonly used. A basic principle in fluorescence microscopy is the highly specific visualization of cellular components with the help of a fluorescent agent. A revolution in cell biological imaging has resulted from the discovery (), gene cloning (), and heterologous expression of the green fluorescent protein (GFP) from the jellyfish Aequorea victoria [reviewed in ()].Expression of GFP alone or in most genetic fusions with other proteins results in visible fluorescence (Fig. The primary objective is to aggregate structured and searchable FP data that is of interest to the imaging community and FP developers.
