Aequorea victoria GFP (rekombinantes Protein)-unkonj.

Green fluorescent protein (GFP) is a 27kD protein which was originally identified in the photo organs of Aequorea victoria (A. victoria) jellyfish. GFP is a naturally fluorescent protein which emits green light at a maximum wavelength of 509 nm when excited by blue or UV light. In A.victoria, calcium ions bind and activate the protein aequorin causing the release of blue fluorescence, which is then absorbed by GFP resulting in the release of green fluorescence. In the laboratory, the GFP protein has been used extensively as a reporter molecule to label, and study, cellular and subcellular proteins in living cells using a wide range of biological applications, including oncology, cardiovascular diseases, brain research, embryology and plant sciences, just to name a few. For the quantitation of the expression of a specific protein, tagged with GFP in these model systems, antibodies to GFP have proven to be of value in immunoblotting studies and ELISA protocols.
