Data Sheet

GFP (2D4) Antibody



Green fluorescent protein (GFP) was first isolated from jellyfish Aequorea victoria, and has been used as a reporter or a tag of fusion protein for expression analysis in molecular and cell biology. Different mutants of GFP have been engineered to produce varieties of colors such as blue (BFP), cyan (CFP) and yellow (YFP). These color mutants provide powerful tools for fluorescence microscopy studies as they are less harmful in living cells, and in vivo imaging as they are heritable and can be expressed throughout an animal. In the presence of long-wave UV light, GFP emits green light, which has a major excitation peak at a wavelength of 395 nm. Studies have shown that GFP is an exceptionally stable protein in a wide range of pH and temperature.


This is a mouse monoclonal antibody, which was raised against the full-length GFP protein.
