GFPfamilien

GFPfamilien refers to a family of fluorescent proteins that are derived from or related to Green Fluorescent Protein (GFP). These proteins exhibit a wide range of fluorescence colors, including blue, cyan, yellow, and red, in addition to the original green. The discovery and subsequent characterization of GFP from the jellyfish Aequorea victoria opened up a vast field of research into fluorescent proteins. Scientists have engineered numerous variants of GFP by altering its amino acid sequence, leading to improved brightness, photostability, and different spectral properties. These GFPfamilien proteins are invaluable tools in molecular biology and cell biology. They are widely used as reporters to track gene expression, visualize protein localization within cells, and monitor cellular processes in real-time. Their ability to emit light upon excitation by specific wavelengths allows for non-invasive observation of biological events without the need for exogenous labels that could interfere with cellular function. The diversity within the GFPfamilien has expanded the possibilities for multi-color labeling experiments, enabling researchers to simultaneously track multiple molecules or cellular structures. This broad utility has made GFP and its relatives indispensable in fields ranging from basic research to medical diagnostics and drug discovery.
