Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.

β-Arrestins were discovered due to their ability to modulate interactions between the phosphorylated β2-Adrenergic receptors and G proteins. This modulation results in diminished β2-Adrenergic receptor function, also known as desensitization. Because arrestins are found at the synaptic terminals, they may provide a termination mechanism that allows the neurons to regain their original polarization and respond to a new neurotransmitter stimulus. The C-terminal region of arrestins is involved in selecting the phosphorylated and activated adrenergic receptors. The β-Arrestin1 gene encodes a protein of 418 amino acids with an approximate molecular weight of 55kDa. β-Arrestin1 protein is highly homologous to the 45kDa β-Arrestin2. Both proteins are widely expressed, but are especially abundant in the central nervous system.

This antibody is routinely tested by western blot analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.

Format Details
Down Arrow Up Arrow
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
