The Green Fluorescent Protein (GFP) from the jellyfish Aequorea victoria is used as a fluorescent indicator for monitoring gene expression in a variety of cellular systems, including living organisms and fixed tissues. Unlike other bioluminescent reporters, GFP fluoresces in the absence of substrates, cofactors, or other intrinsic or extrinsic proteins. Purified GFP is a 27 kDa monomer consisting of 238 amino acids and emits green light (emission maximum at 509 nm) when excited with blue or UV light.
AB3080 is made against highly-purified native GFP from Aequorea victoria. It is reactive with GFP from both native and recombinant sources. While other commercial antibodies to GFP typically demonstrate strong reactivity with E. coli, the AB3080 GFP antibody has been purified by Protein A chromatography, followed by extensive adsorption against whole E. coli BL21 strain cells, giving them minimal cross-reactivity with E. coli.
Highly purified native GFP from Aequorea victoria.
Epitope Tags & General Use
Research Sub Category
This Anti-Green Fluorescent Protein Antibody is validated for use in ELISA, IC, IH, WB for the detection of Green Fluorescent Protein.
A previous lot of this antibody was used in western blot.
A 1:2000-1:10,000 dilution of a previous lot was used in Enzyme-linked Immunosorbent Assay.
Note: While AB3080 has been adsorbed against E. coli proteins, most secondary antibodies have not. To reduce the likelihood of E. coli reactivity from a secondary antibody, we suggest the use of Millipore’s highly-purified secondary antibodies in indirect detection systems.
Optimal working dilutions must be determined by end user.
Routinely evaluated by immunocytochemistry on RENCX cells.
Immunocytochemistry Analysis: Confocal fluorescent analysis of RENCX constitutively expressed GFP using this lot of anti-GFP Rabbit pAB (Red). Green indicates the expressed GFP.
GFP is 27 kDa Dependent upon the molecular weight of the fusion protein being detected.
Protein A purified
Purified rabbit polyclonal IgG in 10 mM Tris buffer, pH 7.2 with 0.01% sodium azide.
Storage and Stability
Stable for 1 year at -20ºC from date of receipt.
Upon receipt, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
