  • 描述
    兔多克隆抗体to Dopamine D2 Receptor
  • 宿主
  • 特异性
    Cross reacts 100% with D2 dopamine receptor, 70% with D2S dopamine receptor and 60% with D2L dopamine receptor. Does not cross react with D1, D3, D4 or D5 dopamine receptors. Western immunoblots using whole rat brain homogenate resulted in a pair of bands being detected at ~48 and ~51kDa.

Our Abpromise guarantee covers the use of ab21218 in the following tested applications.

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

应用 Ab评论 说明
IP Use at an assay dependent concentration. PubMed: 18261457
WB 1/800. Detects a band of approximately 48-51 kDa.Can be blocked with Dopamine D2 Receptor peptide (ab219840).

We recommend incubating with the antibody for 1h if the background is high as well as diluting the antibody further. Also blocking with non-bovine products (e.g. goat milk, normal goat serum) is recommended. Use of cow milk or BSA is not preferred.

Dilution optimised using chromogenic detection, and we recommend diluting further when using chemiluminescent substrates.

ELISA Use at an assay dependent concentration.
ICC 1/5000.


  • 功能
    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.
  • 疾病相关
    Defects in DRD2 are associated with dystonia type 11 (DYT11) [MIM:159900]; also known as alcohol-responsive dystonia. DYT11 is a myoclonic dystonia. Dystonia is defined by the presence of sustained involuntary muscle contractions, often leading to abnormal postures. DYT11 is characterized by involuntary lightning jerks and dystonic movements and postures alleviated by alcohol. Inheritance is autosomal dominant. The age of onset, pattern of body involvement, presence of myoclonus and response to alcohol are all variable.
  • 序列相似性
    Belongs to the G-protein coupled receptor 1 family.
