Recombinant full length protein corresponding to GFP.
Please note that a mistake was made in reference 4 (Mesaeli et.al., J. Cell. Biol. 1999 Mar 8;144(5):857-68). The antibody used for immunohistochemistry on paraformaldehyde fixed tissues was the crude serum version of this antibody (Abcam ab290) and not Clontech's monoclonal as stated. This product is supplied in 25% glycerol. During freezeing and thawing some phase separation might occur - Please ensure that the solution is mixed thoroughly but GENTLY before use.
This antibody (ab6556) is the purifed version of our best-selling rabbit polyclonal to GFP (ab290). It has been developed specifically for use in applications requiring a high titre and specificity with minimum background such as immuno-electron microscopy.
This anti-GFP antibody recognizes the enhanced form of GFP as well.
Our Abpromise guarantee covers the use of ab6556 in the following tested applications.
|IHC-FoFr||Use at an assay dependent concentration. PubMed: 19563657|
|IHC-P||1/1000. Perform heat mediated antigen retrieval via the microwave method before commencing with IHC staining protocol.|
|IP||Use at an assay dependent concentration. Use Protein A agarose for IP.|
|WB||1/1000 - 1/5000.|
|Flow Cyt||Use at an assay dependent concentration.
ab171870 - Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.
ab6556 at 1/500 dilution staining GFP in mouse testis by immunohistochemistry (frozen sections). Sections were paraformaldehyde fixed prior to blocking in 100% serum for 1 hour at 37°C and then incubated with ab6556 for 1 hour at 37°C. A Texas Red conjugated chicken polyclonal to rabbit Ig, diluted 1/100, was used as the secondary antibody.
This image shows a single primary hippocampal neuron from a primary culture overexpressing GFP stained with ab6556 at a dilution of 1/2000. This picture was kindly supplied as part of the review submitted by one of our customers.
ab6556 staining GFP in mouse tooth tissue section by Immunohistochemistry (Frozen sections) without fixation. Tissue samples were blocked with 1% BSA for 20 minutes at 20oC. The sample was incubated with primary antibody (1/500) for 2 hours at 20oC. An Alexa Fluor®488-conjugated Chicken polyclonal to rabbit IgG was used as secondary antibody at 1/200 dilution. Immunofluorescent localization of CD31 and GFP in implanted non GFP cultured molars in GFP adult mice showed the origin of neo-formed blood vessels.

This image shows IF using GFP-expressing glial cells (green) transplanted into lesioned rat spinal cord. This was detected using ab6556 anti-GFP antibody and a FITC conjugated secondary antibody. Axons are labelled red by an antibody to neurofilament-200 and a rhodamine secondary. ab6556 reveals the morphology of the transplanted cells to such an extent that their close interactions with axons are obvious. The top picture shows an optical section from a confocal microscope scan showing how a GFP cell wraps around a branched axon travelling longitudinally. The bottom picture consists of an optical section from another confocal scan showing a GFP cell enveloping an axon in the transverse plane. Review by Andrew Toft submitted 19 May 2004.
Specific labeling of a Trk-GFP fusion protein being synthesized on ER in sympathetic neurons infected with an adenovirus carrying the construct. The gold is associated with the ER membranes. This was done using a 1/5000 dilution of affinity purified antibody (ab6556). The tissue section was fixed and embedded using durcupan resin.
