Biological Activity
SIB-1553A displaces the binding of [H]nicotine (NIC) to the rat brain nAChRs with an IC50 value of 110 nM[1].
In calcium flux assays, SIB-1553A (0.1-5 μM), shows a greater selectivity for beta4-subunit containing recombinant hnAChRs (alpha2beta4, alpha3beta4 and alpha4beta4) vs. beta2-subunit containing nAChRs (alpha4beta2 and alpha3beta2) both in terms of efficacy and potency[2].

* In solvent : -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture)
Solvent & Solubility
H2O : ≥ 100 mg/mL (365.20 mM)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
