Form
Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
Basically, we can dispatch the products out in 3-7 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

Target Background

Function
Ionotropic receptor with a probable role in the modulation of auditory stimuli. Agonist binding induces a conformation change that leads to the opening of an ion-conducting channel across the plasma membrane. The channel is permeable to a range of divalent cations including calcium, the influx of which may activate a potassium current which hyperpolarizes the cell membrane. In the ear, this may lead to a reduction in basilar membrane motion, altering the activity of auditory nerve fibers and reducing the range of dynamic hearing. This may protect against acoustic trauma. May also regulate keratinocyte adhesion.

  2. Behavioural and physiological stress-induced changes observed in alpha9-nAChR KO mice demonstrate a novel role of the alpha9alpha10-nAChR in mounting a normal stress response. The lack of functioning alpha9alpha10-nAChRs leads to negative affective changes after a relatively short period of stress. KO mice exhibited unusual patterns of circadian activity and a dysfunction in reward seeking after a period of reduced acc... PMID: 28408300

  4. The rare variants in CHRNA9 were significantly associated with smoking status. PMID: 25450229
  5. Our findings support a significant interaction effect existing between the CHRNA9 gene and smoking exposure on the risk of breast cancer development. PMID: 25142973
  6. CHRNA9 polymorphisms are associated with non-small cell lung cancer. PMID: 24676996
  7. Thia case-control analysis revealed that an increased risk of lung cancer is associated with two SNPs in CHRNA9, rs56159866 and rs6819385. PMID: 22280835
  8. Data suggest that the biologic activities of Alpha9 nicotinic receptor (CHRNA9) may be regulated at the splicing level, and genetic polymorphisms in CHRNA9 affecting protein levels, amino acid sequence and RNA splicing may influence the risk for lung cancer. PMID: 22125646

  10. Estrogen receptor-alpha plays a central role in mediating alpha9-nAChR gene up-regulation in response to either nicotine or estradiol stimulation. PMID: 20953833
  11. Significant increases in the alpha9-nAChR mRNA and protein levels in MCF-7 cells were detected 6 h after nicotine treatment. Nicotine- and estrogen-induced alpha9-nicotinic acetylcholine receptor upregulation was blocked by (-)-epigallocatechin-3-gallate. PMID: 21370452
  12. These results suggest that alpha9-nAChR-mediated cyclin D3 overexpression is important for nicotine-induced transformation of normal human breast epithelial cells. PMID: 20229177
  13. The alpha9-nAChR is important for nicotine-induced transformation of normal human breast epithelial cells. Results imply that receptor-mediated carcinogenic signals play a decisive role in biological functions related to human breast cancer development. PMID: 20733118
