This Beta Arrestin 2 antibodyis to be used only for research purposes and not for diagnostics..
If you buy Antibodies supplied by NJS poly they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.
An amino acid sequence from the C-terminus of human ARRB2 (RLKGMKDDDYDDQLC) was used as the immunogen for this Beta Arrestin 2 antibody.
The stated application concentrations are suggested starting amounts. Titration of the Beta Arrestin 2 antibody may be required due to differences in protocols and secondary/substrate sensitivity.
Human (Homo sapiens), Mouse (Mus musculus), Rat ; Due to limited knowledge and inability to test the antibody against all known species, we cannot guarantee that no other cross reactivity can occur.
After reconstitution, the Beta Arrestin 2 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20 deg. Celcius or lower. Cycles of freezing and thawing can denaturate the peptide chains of the antibodies and reduce their sensitivity and/or change their affinity. Prepare aliqotes in such a manner so that freeze-thaw cycles are minimized. Avoid repeated freezing and thawing.
Beta Arrestin 2 is an intracellular protein that in humans is encoded by the ARRB2 gene. Members of the 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, as well as having signalling roles in their own right. Arrestin beta 2, like arrestin beta 1, was shown to inhibit beta-adrenergic receptorfunction in vitro. It is expressed at high levels in the central nervous system and may play a role in the regulation of synaptic receptors. Beta-arrestins were originally discovered in the context of heterotrimeric G protein-coupled receptor desensitization, but they also function in internalization and signaling of these receptors.
