Our Abpromise guarantee covers the use of ab40655 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

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).Can be blocked with Dopamine Receptor D3 peptide (ab137997). Blocking with 5% goat or donkey serum significantly reduces background as compared to BSA or milk.


  • FunctionThis 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 specificityBrain.
  • Involvement in diseaseGenetic 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 similaritiesBelongs to the G-protein coupled receptor 1 family.
  • Post-translational
    Phosphorylated by GRK4 (GRK4-alpha and GRK4-gamma).
  • Cellular localizationCell 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.

Anti-Dopamine Receptor D3 antibody images

  • 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.

Abcam guarantees this product to work in the species/application used in this Abreview.
Application Flow Cytometry
Sample Rat Cell (Spleen cells)
Specification Spleen cells
Preparation 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.
