Target

RelevanceFunction: 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. -

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.

Exposure time: 25 minutesWestern blot analysis of HEK293 transfected and untransfected cell lysates, labelling GFP with ab13970. Cells were treated by mixing in RIPA buffer and denaturating in Laemmli buffer for 5 mins at 95°C. The gel was Precast at 4-12%. Blocking was with 0.5% milk at 20°C for 5 mins.

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. -

Immunocytochemistry/ Immunofluorescence - Anti-GFP antibody (ab13970)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 Goat Anti-Chicken IgY H&L (Alexa Fluor® 488) preadsorbed (ab150173), 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). -

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.
