Neuronal acetylcholine receptor subunit alpha-10 (CHRNA10), partial, human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 25-240aa. Protein Length: Partial. Tag Info: N-terminal GST-tagged. Target Protein Sequence: AEGRLALKLF RDLFANYTSA LRPVADTDQT LNVTLEVTLS QIIDMDERNQ VLTLYLWIRQ EWTDAYLRWD PNAYGGLDAI RIPSSLVWRP DIVLYNKADA QPPGSASTNV VLRHDGAVRW DAPAITRSSC RVDVAAFPFD AQHCGLTFGS WTHGGHQLDV RPRGAAASLA DFVENVEWRV LGMPARRRVL TYGCCSEPYP DVTFTLLLRR RAAAYV. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. 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. Storage: 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. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Ionotropic receptor with a probable role in the modulation of auditory stimuli. Agonist binding may induce an extensive change in conformation that affects all subunits and leads to 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. Reference: "Conotoxin alphaD-GeXXA utilizes a novel strategy to antagonize nicotinic acetylcholine receptors."
