Synthetic peptide conjugated to KLH derived from within residues 300 to the C-terminus of Human Doublecortin.
(Peptide available as ab19804.)
Our Abpromise guarantee covers the use of ab18723 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||Use a concentration of 1 µg/ml. Detects a band of approximately 45 kDa (predicted molecular weight: 40-45 kDa).|
|ICC||Use at an assay dependent concentration.|
|ICC/IF||Use a concentration of 1 - 5 µg/ml.|
|IHC-FrFl||1/1000. Please note: Low dilutions of this antibody can cause high background. Please use as high a dilution as possible. Optimal working dilutions are batch dependent.|
|IHC-Fr||1/2000 - 1/7000.|
|IHC-P||Use a concentration of 0.1 - 1 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.|
ab18723 staining Doublecortin in mouse embryonic 15 day brain tissue sections by Immunohistochemistry (PFA perfusion fixed frozen sections). Tissue samples were fixed by perfusion with paraformaldehyde, permeablized with 0.5% Triton X-100 in PBS, blocked with 10% serum for 1 hour at 25°C and antigen retrieval was by heat mediation in citrate buffer, pH 6. The sample was incubated with primary antibody (1/500 in PBS + 0.1% Triton X-100 + 1% serum) for 16 hours at 25°C. An Alexa Fluor® 594-conjugated donkey anti-rabbit IgG polyclonal (1/700) was used as the secondary antibody.
IHC-Fr image of Doublecortin staining in Mouse adult dentate gyrus sections using ab18723(1:100). The sections were fixed in paraformaldehyde and permeabilized using 1x TBST. The sections were then blocked using 10% donkey serum for 1 hour at 25°C. ab18723 was diluted 1:100 and incubated with the sections for 12 hours at 25°C. The secondary antibody used was Donkey anti-rabbit conjugated to Cy3 Dye (1:500). DAPI was used to stain the nuclei.
ab18723 staining 6 week rat brain tissue dentate gyrus (DG) by IHC-P using rabbit-specific EXPOSE IHC detection kit (ab80437). Formalin fixed paraffin embedded tissue sections were pre-treated using heat mediated antigen retrieval (using a pressure cooker) with sodium citrate buffer (pH6) for 30 mins. The section was incubated with ab18723, 0.1µg/ml, for 1 hour at room temperature. DAB was used as the chromogen and the section was counterstained with haematoxylin and mounted with DPX.
Doublecortin antibody (ab18723; green) labeling cell extensions consistent with dendrite morphology in 4 day old cultures. Preincubation of ab18723 with its immunising peptide (ab19804) quenched immunostaining (see review).
Dorsal root ganglion explants were dissected from 16 day-old rat embryos and cultured for 4 days in vitro with Neurobasal Medium containing 10% fetal calf serum and B27 supplement. Immunocytochemistry: All steps were performed in PBS. Cells or explants were fixed in 4% PFA for 15min, permeabilised with 0.1% TX100 for 10min and blocked with 5% BSA, 0.1% TX100 for 45min. ab18723 was incubated at 5µg/ml for 12h in 5% BSA, 0.1% TX100 at 4°C. For peptide blocking experiments preincubation of the peptide (ab19804; 250µg/ml) and antibody (5µg/ml ) was performed for 2h at 37°C. Cultures were washed (3x) of primary antibody solution. Goat anti-rabbit AlexaFluor 488 was used as secondary antibody (1/400) in 5% BSA, 0.1% TX100 for 2h at R
ab18723 at 1/2000 staining mouse brain svr: progenitor olfactory neurones by IHC-P. The tissue was formaldehyde fixed and a heat mediated antigen retrieval step was performed before incubation with the antibody for 16 hours. An Alexa-Fluor ® 488 conjugated goat antibody was used as the secondary (green). The tissue was also stained for Ki67 (shown in red).
