Application Abreviews Notes
ICC/IF 1/5000. Stains specific cells in various regions of PLP-fixed rat brain sections including dedritc labelling in the molecular layers as well as the plasma membranes of neurons in layer 5 or cortex and the glomeruli of the olfactory bulb.
Flow Cyt Use at an assay dependent concentration.

ab171870 - Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.


WB 1/500. Detects a band of approximately 50 kDa (predicted molecular weight: 44 kDa). Blocking with 5% goat or donkey serum significantly reduces background as compared to BSA or milk.


  • Function

    This is one of the five types (D1 to D5) of receptors for dopamine. The activity of this receptor is mediated by G proteins which inhibit adenylyl cyclase. Promotes cell proliferation.
  • Tissue specificity

  • Involvement in disease

    Genetic variation in DRD3 is associated with essential tremor hereditary type 1 (ETM1) [MIM:190300]. ETM1 is the most common movement disorder. The main feature is postural tremor of the arms. Head, legs, trunk, voice, jaw, and facial muscles also may be involved. The condition can be aggravated by emotions, hunger, fatigue and temperature extremes, and may cause a functional disability or even incapacitation. Inheritance is autosomal dominant.
  • Sequence similarities

    Belongs to the G-protein coupled receptor 1 family.
  • Post-translational

    Phosphorylated by GRK4 (GRK4-alpha and GRK4-gamma).
  • Cellular localization

    Cell membrane. Both membrane-bound and scattered in the cytoplasm during basal conditions. Receptor stimulation results in the rapid internalization and sequestration of the receptors at the perinuclear area (5 and 15 minutes), followed by the dispersal of the receptors to the membrane (30 minutes). DRD3 and GRK4 co-localize in lipid rafts of renal proximal tubule cells.

  • ab40655 stained PC12 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab40655 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

All our antibodies are for research purposes only and not for diagnostic or therapeutic ends. We therefore mainly test our products in in vitro application such as WB and IHC. All four antibodies mentioned have not been tested in vivo however this does not mean that they will not be suitable provided that this in vivo testing is not in humans and is in mouse or rat.

If you wanted to do in vivo testing, please note that Anti-Dopamine Transporter antibody (ab111468) and Anti-Dopamine Transporter antibody (ab111468) have 0.02% sodium azide in them as a preservative and that this would have to be removed before in vivo testing in rats as it could be harmful to them.

Thank you for contacting us with your questions, and for yourpatience while I have been in touch with the lab regarding your enquiry.

I have confirmed with the lab that this is taken from the human DRD3 amino acid sequence, which can be found toward the bottom of the UniProt page below:


The immunogen corresponds to the N-terminalamino acids 2-10including an extra cysteine.

I hope this information will be useful but if you have any further questions or if there is anything else that we can do for you, please let me know and I'll be happy to help.

Thank you for your enquiry.

I am sorry to confirm that regrettablythese lot numbers for these antibodies are no longer available. These are very old lot numbers.

Should you have any further questions, please do not hesitate to contact us.

Thank you for contacting us.
We currently haven't tested this antibody in immunohistochemistry so we do not know how this antibody behaves in IHC. The DDR3 receptors localizes either in cytoplasm or membrane so the staining should be cytoplasmic or membranous rather than nuclear. There are many publication that actually evidenced the expression of the protein in cytoplasmic region. It will be worth to check the protocol they have been using.
I look forward to hearing from you soon. Please do not hesitate to contact us if you have any question.

Cell harvesting/tissue preparation method: Spleen cell suspensions were obtained by gently grinding tissue into RPMI 1640 culture medium (Sigma-Aldrich, Steinheim, Germany) under sterile conditions. Mononuclear cells were separated by Ficoll–Hypaque density gradient (1.083 g/ml) centrifugation. The mononuclear cells concentrated at the surface were collected and washed twice in RPMI 1640 medium. After cell counting, 1 x 10 6 cells/sample were stained with the corresponding antibodies.
