Biological Activity
Description
In Vitro
PrP (106-126) (100 μM) induces mTOR phosphorylation over time in N2a cells. PrP (106-126)-treated cells show significantly increased ROS production in comparison with that of PBS-treated control cells. Knockdown of PRAS40 enhances PrP (106-126)-induced apoptosis. PRAS40 alleviates PrP (106-126)-induced neuronal apoptosis via mTOR-AKT activation[1]. PrP (106-126) interacts selectively with porcine brain endothelial cells (PBEC) via their luminal side, and causes cumulative cell death, as shown by lactate dehydrogenase release, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide reduction, Caspase 3 induction and direct cell counting. In addition, PrP (106-126), but not its corresponding scrambled peptide, produces a 50% reduction of the trans-endothelial electrical resistance, while the PBEC maintained confluency[2].

Solvent & Solubility
In Vitro:
DMSO : 50 mg/mL (26.15 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 1 mg/mL (0.52 mM; Need ultrasonic and warming)
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.
