Orexin B, rat, mouse TFA
Based on 2 publication(s) in Google Scholar
Orexin B, rat, mouse (Rat orexin B) TFA is an endogenous orexin receptor agonist. Orexin B, rat, mouse TFA binds and activates two closely related orphan G protein-coupled receptors OX1-R and OX2-R. Orexin B, rat, mouse TFA stimulates food intake and energy expenditure and plays a significant role in sleep-wakefulness regulation.

OX2 Receptor |
OX2 receptor is indeed a high-affinity receptor for human orexin B, with an IC50 of 36 nM in the binding assay and an EC50 of 60 nM in the [Ca2+]i transient assay. Human Orexin B has significantly lower affinity for the human OX1: the calculated IC50 in the competitive binding assay and the EC50 in the [Ca2+]i transient assay are 420 nM and 2500 nM for human orexin-B, respectively[2].

Solvent & Solubility
H2O : 100 mg/mL (32.78 mM; Need ultrasonic)
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.
