• Reactivity: Human
• Synonyms: beta-arrestin 2; ARRB2; Human beta-arrestin 2; ARRB2 ELISA Kit; ARRB2 elisa kit

• Reactivity: Human
• Specificity: No significant cross-reactivity or interference between Human ARRB2 and analogues was observed.

• Samples: Serum, Plasma, Tissue Homogenate, Feces and Urine
• Assay Type: Sandwich
• Detection Range: 31.2 pg/ml - 1000 pg/ml.
• Sensitivity: 5.0 pg/ml.
• Intended Uses: This Quantitative Sandwich ELISA kit is only for in vitro research use only, not for drug, household, therapeutic applications! It is intended to be determinated ARRB2 concentrations in Human serum, plasma and other body fluids. Using Purified Human ARRB2 antibody to coat Microelisa Stripplate wells to make solid-phase antibody, then add ARRB2 and ARRB2 antibody which has been labeled with HRP to wells, then the reactants become antibody-antigen-antibody-enzyme complex, after washing completely, add TMB substrate solution, TMB substrate becomes blue color under HRP enzyme-catalyzed, reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. The concentration of ARRB2 in the samples is then determined by comparing the O.D. of the samples to the standard curve.
• Intra-assay Precision: Intra-assay CV (%) is less than 15%.
• Inter-assay Precision: Inter-assay CV (%) is less than 15%. [CV(%) = SD/mean ×100]
• Preparation and Storage: Store all reagents at 2-8 degree C

NCBI Description

Members of arrestin/beta-arrestin protein family are thought to participate in agonist-mediated desensitization of G-protein-coupled receptors and cause specific dampening of cellular responses to stimuli such as hormones, neurotransmitters, or sensory signals. Arrestin beta 2, like arrestin beta 1, was shown to inhibit beta-adrenergic receptor function in vitro. It is expressed at high levels in the central nervous system and may play a role in the regulation of synaptic receptors. Besides the brain, a cDNA for arrestin beta 2 was isolated from thyroid gland, and thus it may also be involved in hormone-specific desensitization of TSH receptors. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2012]

Uniprot Description

ARRB2: a member of the arrestin/beta-arrestin protein family. These proteins participate in agonist-mediated desensitization of G-protein-coupled receptors. Acts as a cofactor in the beta-adrenergic receptor kinase (BARK) mediated desensitization of beta-adrenergic receptors. Expressed at high levels in the CNS and peripheral blood leukocytes.
