Target

  • Relevance
    Function: Energy-transfer acceptor. Its role is to transduce the blue chemiluminescence of the protein aequorin into green fluorescent light by energy transfer. Fluoresces in vivo upon receiving energy from the Ca2+ -activated photoprotein aequorin.

    Subunit structure: Monomer.

    Tissue specificity: Photocytes.

    Post-translational modification: Contains a chromophore consisting of modified amino acid residues. The chromophore is formed by autocatalytic backbone condensation between Ser-65 and Gly-67, and oxidation of Tyr-66 to didehydrotyrosine. Maturation of the chromophore requires nothing other than molecular oxygen.

    Biotechnological use: Green fluorescent protein has been engineered to produce a vast number of variously colored mutants, fusion proteins, and biosensors. Fluorescent proteins and its mutated allelic forms, blue, cyan and yellow have become a useful and ubiquitous tool for making chimeric proteins, where they function as a fluorescent protein tag. Typically they tolerate N- and C-terminal fusion to a broad variety of proteins. They have been expressed in most known cell types and are used as a noninvasive fluorescent marker in living cells and organisms. They enable a wide range of applications where they have functioned as a cell lineage tracer, reporter of gene expression, or as a measure of protein-protein interactions. Can also be used as a molecular thermometer, allowing accurate temperature measurements in fluids. The measurement process relies on the detection of the blinking of GFP using fluorescence correlation spectroscopy.

    Sequence similarities: Belongs to the GFP family.

    Biophysicochemical properties: Absorption: Abs(max)=395 nm
    Exhibits a smaller absorbance peak at 470 nm. The fluorescence emission spectrum peaks at 509 nm with a shoulder at 540 nm.

Anti-GFP antibody images

  • ab13970 staining GFP in Human U2OS cells by ICC/IF. Cells were paraformaldehyde fixed, permeabilized with 0.5% triton and blocked with 2% antibody dilution buffer for 2 hours. Cells were incubated with the primary antibody (1/1000) for 1 hour at 25°C. An undiluted  Alexa Fluor® 488 conjugated Goat anti-chicken polyclonal was used as the secondary antibody.

  • ab13970 staining GFP in murine lung tissue by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections).
    Tissue was fixed in paraformaldehyde and a heat mediated antigen retrieval step was performed using citrate buffer. Samples were then permeabilized with 0.1% Tween, blocked with 15% serum for 30 minutes at 23°C and then incubated with ab13970 at a 1/500 dilution for 14 hours at 4 °C. The secondary used was an Alexa-Fluor 488 conjugated goat anti-chicken polyclonal used at a 1/500 dilution.

  • ab13970 staining mouse olfactory epithelium tissue sections by IHC-Fr. The sample was PFA fixed and blocked with 4% BSA/ 5% NFDM/ 10% NDS for 15 minutes at 20°C.  The primary antibody was diluted 1/1000 and incubated with the sample for 1 hour.   A FITC conjugated goat anti-chicken was used as the secondary.

    This colony is the result of retroviral infection with a control virus.  The GFP is under the control of an IRES promoter, so its expression is independent of any other protein.  The counter-stain is hoescht.

  • ab13970 staining GFP in GFP-transfected NIH3T3 cells. The cells were fixed with 4% formaldehyde (10min) and then blocked in 1% BSA / 0.3M glycine in 0.1%PBS-Tween for 1h. The cells were then incubated with ab13970 at 1/2000 dilution overnight at +4°C followed by incubation with ab150173, Goat polyclonal Secondary Antibody to Chicken IgY - H&L (Alexa Fluor® 488), for 1 hour, at 1μg/ml.
    Under identical experimental conditions, when compared to the basal level of GFP expression in transfected NIH3T3 cells, the cells upon which ab13970 was applied gave a stronger signal in the 488 channel, indicating that ab13970 is binding to GFP and therefore eliciting signal amplification.
    ab13970 was also applied to non-GFP-transfected NIH3T3 cells, which produced no positive staining, indicating specificity for GFP. Nuclear DNA was labelled with 1.43μM DAPI (blue).
