Description

Description: This GF28R monoclonal antibody reacts with green-fluorescent protein (GFP), which was originally isolated from the cnidarian Aequorea victoria. This 27-kDa protein absorbs blue light (maximally at 395 nm) and emits green light (peak at 509) without the requirement of exogenous substrates and cofactors. These unique qualities allow GFP to be used to monitor gene expression and protein localization in vivo. Several mutant forms of GFP have been developed which fluoresce more intensely and have shifted excitation maxima when compared to wildtype GFP, making them useful for flow cytometry, fluorescence microscopy, and double-labeling applications. This antibody is capable of staining formaldehyde fixed cells. Applications Reported: This GF28R antibody has been reported for use in immunoprecipitation, and western blotting. Applications Tested: This GF28R antibody has been tested by immunoblotting of reduced cell lysate expressing GFP at less than or equal to 1 μg/ mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 μm post-manufacturing filtered.

The jellyfish Aequorea victoria contains green fluorescent protein (GFP Tag) that emits light in the bioluminescence reaction of the animal. GFP has been used widely as a reporter protein for gene expression in eukaryotic and prokaryotic organisms, and as a protein tag in cell culture and in multicellular organisms. As a fusion tag, GFP can be used to localize proteins, to study their movement or to research the dynamics of the subcellular compartments where these proteins are targeted. GFP technology has revealed considerable new insights in the physiological activities of living cells. GFP is a 27 kDa monomeric protein, which autocatalytically forms a fluorescent pigment. The wild type protein absorbs blue light (maximally at 395nm) and emits green light (peak emission 508nm) in the absence of additional proteins, substrates, or co-factors. GFP fluorescence is stable, species independent and is suitable for a variety of applications. GFP has been used extensively as a fluorescent tag to monitor gene expressin and protein localization. Moreover, other applications for GFP include its use in assessing protein protein interactions in the yeast two hybrid system, and in measuring distances between proteins in fluorescence energy transfer (FRET) experiments.
