Lyophilized To keep the original salt concentration, we recommend reconstituting to the original concentration prior to lyophilization (see Concentration) in ddH2O. If a lower concentration is required, dilute in PBS, pH 7.4. If a higher concentration is required, the product can be reconstituted directly in PBS, pH 7.4, though please note that this will change the overall salt concentration. The stock concentration should be between 0.1-1.0 mg/ml. Do not vortex.

WB, SDS-PAGE

Prior to lyophilization: PBS, pH 7.4, containing 0.01% Sarcosyl, 1 mM DTT, 5% Trehalose and Proclin-300.

Descripción

DRD4 is a Gi/o-coupled G protein-coupled receptor of the D2-like dopamine receptor family, primarily expressed in brain regions associated with cognition, emotion, and reward, such as the prefrontal cortex, amygdala, and hippocampus. DRD4 plays a significant role in modulating attention, impulse control, and executive function, and its dysfunction has been linked to attention-deficit hyperactivity disorder (ADHD), schizophrenia, and other neuropsychiatric disorders. Notably, DRD4 is highly polymorphic, with variations in its gene (e.g., the 7-repeat allele) associated with ADHD susceptibility, novelty-seeking behavior, and addiction. DRD4 signaling inhibits adenylate cyclase activity, leading to reduced cyclic AMP (cAMP) levels, and influences downstream pathways like MAPK and protein kinase C (PKC), regulating neuronal excitability and plasticity. In addiction, DRD4 contributes to reward sensitivity and reinforcement learning, making it a target for substance abuse treatment. DRD4 is also expressed in peripheral tissues, where it modulates cardiovascular function and immune responses. Its polymorphic nature and role in attention and behavior make DRD4 a key target for ADHD therapeutics and neuropsychiatric research.

Dopamine Receptor D4 (DRD4) Antibody

DRD4 Antibody is a Rabbit Polyclonal antibody against DRD4. This gene encodes the D4 subtype of the dopamine receptor. The D4 subtype is a G-protein coupled receptor which inhibits adenylyl cyclase. It is a target for drugs which treat schizophrenia and Parkinson disease. Mutations in this gene have been associated with various behavioral phenotypes, including autonomic nervous system dysfunction, attention deficit/hyperactivity disorder, and the personality trait of novelty seeking. This gene contains a polymorphic number (2-10 copies) of tandem 48 nt repeats; the sequence shown contains four repeats.
