製品の詳細Mouse monoclonal [9F9.F9] to GFP
特異性Assayed by ELISA for direct binding of antigen recognizes wild type and recombinant GFP. Well suited to titrate GFP in solution using either form of the antibody as the capture or detection antibodies. Shows no reactivity against red fluorescence protein (RFP). This antibody is known to cross react with the wild type (wt), recombinant (rGFP) and enhanced (eGFP) forms.

Our Abpromise guarantee covers the use of ab1218 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/3000 - 1/30000.
(See Abreviews). Recognises the immunogen under native conditions and reduced/denatured conditions.
|IHC-Fr||1/1000 - 1/5000.
Works also with eYFP.
|Sandwich ELISA||1/80000 - 1/500000. Can be paired for Sandwich ELISA with Goat polyclonal to GFP (Biotin) (ab6658).
ab1218 can be used to detect GFP by ELISA (sandwich or capture) for the direct binding of antigen. Biotin conjugated monoclonal anti-GFP is well suited to titrate GFP in a sandwich ELISA in combination with polyclonal anti-GFP as a capture antibody.
|ICC/IF||Use at an assay dependent concentration.|

関連性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.

TIRFM responses to prolonged stimulation with 10 mM Ca2+
C. Cells expressing BS-wt were stimulated with 0.5 or 10 mM Ca2+ for 60 min, 37°C, followed by fixation, permeabilization, and staining with anti-GFP antibody (secondary antibody tagged with Alexa-568). Confocal images of SEP and anti-GFP fluorescence are shown along with the merged image. D. Experiment as in C for cells expressing BS-5A mutant.
HEK-293 cells were seeded on glass coverslips and transiently transfected with BS-wt or BS-5A cDNAs. Cells were incubated in DMEM containing 0.5 or 10 mM Ca2+ for 1 hr at 37°C, 5% CO2.
