Green fluorescence protein (GFP) is a 27KD protein derived from the jellyfish Aquorea victoria that emits a green light (emission peak at a wavelength of 509 nm) when excited by blue light (excitation peak at a wavelength of 395 nm). GFP is a highly versatile protein that has become an invaluable tool in cell biology research because of its intrinsic fluorescence without substrate requirement, ability to be visualized over time durations - both short- and long-term - in living cells, and short sequence making it easy to clone and use an unobtrusive tag.
GFP (green florescent protein), originally discovered in the jellyfish Aequorea victoria, (1) is one of the most extensively investigated and exploited proteins in the area of life sciences. GFP is well known for its proficiency emit fluorescence and has proven itself as an indicating marker of gene expression and protein target in intact cells and organisms.
Brain-derived neurotrophic factor (BDNF) is known to be important for neuronal differentiation, survival, migration and plasticity in both the developing embryo and adult synapses. The BDNF antibody is also proving to be an important tool in Alzheimer's disease (AD) research.
We at Novus Biologicals have a large antibody catalog targeted to epitope tags. They include C-Myc, GFP, HA, DYKDDDDK, and V5 Tag antibody reagents. The V5 tag antibody recognizes the artificially engineered V5 epitope, which is formed of amino acid residues 95-108 of the simian virus 5 RNA polymerase alpha subunit.
