  • Relevance

    Dopamine (C6H3OH)2-CH2CH2NH2)is a catecholamine neurotransmitter in the brain. Its chemical name is 4-(2-aminoethyl)benzene-1,2-diol. Dopamine is a hormone released by the hypothalamus. Its main function is to inhibit the release of prolactin from the anterior lobe of the pituitary. It can be used as a sympathomimetic drug, producing effects such as increased heart rate and blood pressure.

  • ab6427 staining dopamine in PC12 cells treated with ghrelin (rat) (ab120231), by ICC/IF. Decrease in dopamine expression correlates with increased concentration of ghrelin, as described in literature.
    The cells were incubated at 37°C for 10 minutes in media containing different concentrations of ab120231 (ghrelin) in DMSO, fixed with 100% methanol for 5 minutes at -20°C and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab6427 (1/200 dilution) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat anti-rabbit polyclonal antibody (ab96899) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.

Thank you for contacting us.

ab6427 is not guaranteed for use in immunohistochemistry. However, ab1001 (https://www.abcam.com/ab1001) is guaranteed to work in immunohistochemistry and gave good results when fixed with formalin/PFA in paraffin-embedded sections.

Regarding your question about whether this antibody works on rat tissue, because the immunogen of ab1001 and ab6427 is a Chemical / Small Molecule, the species in which this antibody is used is irrelevant. Therefore both these antibodies should work on rat tissue.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

We have additional information about capturing the DA as follows: After discussion with our research team, we think that the better way is to bind DA on your tissue via glutaraldehyde (0.1 to 1%). - Double bounds are reduced by adding of sodium borohydrure. - Tissue has to be wash for eliminate borohydrure excess. - You have also to make a competition scale between antibody and different concentration of the antigen DA-G-BSA. Had this medium on the tissue. - After revelation by a labelled anti-rabbit antibody, you finally have to estimate the competition rate between DA linked on tissue and soluble DA-G-BSA conjugate.

Thank you for your enquiry. For Immunohistological studies with dopamine antibodies, fixation with glutaraldehyde is required. Please find below a protocol. Perfusion protocol for adult male Sprague-Dawley (weight around 0.5 kg) 1- The animals can be deeply anaesthetized for example with uerethane (0.1-1.5g/kg, intraperitoneal). 2- Heparinized and perfused via the ascending aorta with 100 ml of cold physiologic saline (0.9% NaCl) and with the following fixative solution: a. 300 ml of cold 4% paraformaldehyde and 2% glutaraldehyde in 0.1M Phosphate buffer (PB), pH 7.2 ( in two minutes). b. 600 ml of cold 4% paraformaldehyde and 2% glutaraldehyde in 0.1M PB, pH 7.2 ( in ten minutes). c. Dissect out the brains and place in a solution of 4% paraformaldehyde in 0.1M PB, pH 7.2, at 4°C for twelve to sixteen hours. d. Before brain will be cut on a freezing microtome, we must include it in growing concentrations of sucrose (5 at 30 %). If you have any further questions then please do not hesitate to get back in touch with us.

This antibody is known to work with 3-5% glutaraldehyde perfusion. Protocol is as follows - Perfusion : perfuse intracardially through the aorta using a pump with the following solutions : solution A (30ml) : 200-300ml/min solution B (500ml) : 200-300ml/min Solution A : cacodylate 0.1M, sodium metabisulfite 10g/l, pH = 6.2 Solution B : cacodylate 0.1M, sodium metabisulfite 10g/l and glutaraldehyde 3-5% pH = 7.5 Post fixation : 15 to 30 min in solution B, then 4 soft washes in Tris 0.05M with sodium metabisulfite 8.5g/l, pH 7.5 (solution C). Tissue sectioning : Cryostat or vibratome sections can be used. Reduction step : Sections are reduced with the solution C containing sodium borohydride (0.1M) for 10 min. Then, the sections are washed 4 times with solution C without sodium borohydride. Application of anti-Dopamine antibodies : The final dilution is 1/2,000 to 1/5,000 in solution C containing triton X100 0.1%, plus 2% of non-specific serum. A dozen sections can be incubated with 2ml of antibody solution overnight at 4°C. Then the sections are washed 3 times (10 min) with solution C. N.B. : Antibodies may be used at a higher dilution. The customer should explore the antibody dilution to reduce the possibility of high background. Note that a substitution in the buffer system as used in our protocol may change the background and the antibody recognition. PAP procedure : Secondary antibody : Sections are incubated with 1/100 dilution of goat anti-rabbit in solution C for 3 hours at 20°C or 1 hour at 37°C. Then washed 3 times (10 min) with solution C. PAP : Sections are incubated with 1/1,000 dilution of rabbit peroxidase anti-peroxidase complex in solution C for 1 hour at 37°C. Then wash 3 times (10 min) with solution C. Detection : Antibody-antigen complexes are revealed using diaminobenzidine (25mg/100ml) (or other chromogen) dissolved in Tris 0.05M and filtrated; 0.05% of H2O2 is added. The sections are incubated for 10 min at 20°C. Reaction is stopped by transfering sections in 5ml of Tris 0.05M.
