Buffer If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Target Background

After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane permeable to sodiun ions.
Gene References into Functions
  1. MAFA controls autonomic nervous system-mediated insulin secretion by activating the transcription of nicotinic (ChrnB2 and ChrnB4) receptor genes, which is impaired in patients with type 2 diabetes. PMID: 26904947
  2. Data show efficient expression of (alpha6beta2)2beta3 nicotinic acetylcholine receptors (AChRs) in Xenopus oocytes using free subunits with only small changes in alpha6 subunits, while not altering AChR pharmacology or channel structure. PMID: 25068303
  3. The results of this study suggested that rs2072660 had a significant effect on the nicotine dependence There was no direct association between depressive phenotype (with neither ZSDS total scores and nor its subscales) and CHRNB2 variants. PMID: 25640319
  4. Following smoking reduction and cessation alpha4beta2* nAChR densities were decreased across brain regions. PMID: 23429692
  5. Evidence for significant association between common sequence variants in CHRNB2 and nausea severity was obtained after adjusting for age, gender and correlated tests in patients using varenicline for smoking cessation. PMID: 21606948
  6. A novel mutant mouse harboring the human ADNFLE mutation in the Chrnb2 gene was generated and used to study the roles of beta2* nicotinic receptors in complex biological processes including the activity-rest cycle, natural reward and anxiety. PMID: 20603624
  7. variation in the promoter region of CHRNB2 gene may be important in mediating levels of expression of the beta2 nicotinic receptor subunit, which may be associated with variation in subjective response to nicotine PMID: 20854418
  8. mutations of CHRNB2 and CHRNA2 genes may be rare in Chinese autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) PMID: 21287502
  9. Concatameric pentamers and pentamers formed from combinations of trimers, dimers, and monomers of alpha6beta2beta3* acetylcholine receptors exhibit similar properties, indicating that the linkers between subunits do not alter their functional properties. PMID: 20923852
  10. The high sensitivity to activation and desensitization of (alpha4beta2)alpha5 nAChRbeta2 by nicotine results in a narrow concentration range in which activation and desensitization curves overlap. PMID: 20881005
  11. Using high-resolution NMR spectroscopy, we solved the structure of the entire transmembrane domain (TM1234) of the beta2 subunit. We found that TM1234 formed a four-helix bundle in the absence of the extracellular and intracellular domains. PMID: 20441771
  12. Data suggests that beta(2)*-nAChRs play a role in pain sensitivity but not pain tolerance during tobacco smoking withdrawal. PMID: 20371741
  13. There was no evidence of association of any of the SNPs in CHRNAB2 (rs2072661, rs4845378) or CHRNAB3 (rs4953, rs6474413) with smoking status (p=0.30) or, among daily smokers, of association with cotinine levels (p=0.08). PMID: 19482438
  14. association of a 3' untranslated region polymorphism (rs2072661) in the nicotinic acetylcholine receptor beta2 subunit (CHRNB2) gene with quitting success in response to nicotine versus placebo patch during a short-term test of patch effects. PMID: 19755656
  15. CHRNB2 is a logical candidate for influencing smoking behavior and nicotine dependence PMID: 11906688
  16. autosomal dominant nocturnal frontal lobe epilepsy probands were analyzed for the presence of V287L and V287M mutations in the CHRNB2 gene. No mutations in the analyzed region of CHRNB2 found. PMID: 11952766
  17. Mutations of the gene encoding CHRNB2 may be linked to nocturnal frontal lobe epilepsy. PMID: 12185808
  18. CHRNB2 subunit is expressed in the soma of the majority of pyramidal cells, with the most beta 2 immunoreactivity observed in CA2-4 and entorhinal cortex and relatively less in CA1 and subicular pyramidal cell soma. PMID: 12663058
  19. Mutations in genes coding for the alpha 4 and beta 2 subunits of the neuronal nicotinic acetylcholine receptor receptor (CHRN) are known to cause autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE). PMID: 12681012
  20. A significant association for Alzheimer's disease is observed for a non-coding polymorphism in CHRNB2 subunit. PMID: 15026168
  21. Nicotinic acetylcholine receptor beta 2 subunit polymorphisms are not a useful marker for prediction of the febrile seizures. PMID: 15033200
  22. Here, we report a new CHRNB2 mutation located in transmembrane region 3 (M3), outside the known ADNFLE mutation cluster. The CHRNB2 mutation I312M, which occurred de novo in twins, markedly increases the receptor's sensitivity to acetylcholine. PMID: 15964197
  23. Greater beta2*-nAChR availability during early abstinence may impact the ability of smokers to maintain abstinence. PMID: 16928859
  24. This study provides the first evidence for association between the CHRNB2 gene and nicotine- and alcohol-related phenotypes, and suggests that polymorphisms in CHRNB2 may be important in mediating early responses to nicotine and alcohol. PMID: 17226798
  25. To our knowledge, this is the third family reported presenting a mutation in CHRNB2 in nocturnal frontal lobe epilepsy. PMID: 17900292
  26. These results in living human subjects corroborate postmortem reports of decline in high affinity nicotine binding with age and may aid in elucidating the role of beta(2)-nAChRs in cognitive aging. PMID: 18242781
  27. Genetic testing revealed the CHRNB2 mutation I312M in transmembrane region 3 (M3) of the neuronal nicotinic acetylcholine receptor. PMID: 18534914
  28. An SNP (rs2072661) in the 3' UTR region of the CHRNB2 has an impact on abstinence rates at the end of treatment and after a 6-month follow-up period. PMID: 18593715
