Target GFP Tag Target background Epitope tags have application in the labeling, isolation and detection of proteins using immunoblotting, Immunoprecipitation and immunostaining techniques. The green fluorescent protein (GFP) from the jellyfish Aequorea Victoria is involved in the bioluminescence of the jellyfish. When expressed in prokaryotic cells, GFP produces a fluorescent product, making GFP useful in monitoring physiological processes, visualizing protein localization, and detecting transgenic expression. Immunogen GFP from the jellyfish Aequorea victoria N-terminal peptide-KLH conjugates. Specificity The antibody recognizes native and denatured forms of GFP and its variants such as: EGFP, YFP, EYFP, and CFP. Clone ID GF28R Isotype IgG2b Preservative None Format Purified with protein G, stored in PBS pH 7.4 and lyophilized. Recommend starting dilution If reconstituted with deionized water in 100 µl: WB 1:1000-3,000, IHC 1:500-2,000. Optimal dilution has to be determined by the user. Limitations Research Use Only Storage Lyophilized antibodies can be kept at 4ºC for up to 3 months and should be kept at -20ºC for long-term storage (2 years). To avoid freeze-thaw cycles, reconstituted antibodies should be aliquoted before freezing for long-term (1 year) storage (-80ºC) or kept at 4ºC for short-term usage (2 months). For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made with the assay buffer. After the maximum long-term storage period (2 years lyophilized or 1 year reconstituted) antibodies should be tested in your assay with a standard sample to verify if you have noticed any decrease in their efficacy. To limit antibody loss or degradation, BSA (final concentration 1%) and sodium azide (final concentration 0.02%) can be added to the suggested first dilution. It is important to first verify if those preservatives are compatible with your assay.
