Biological Activity
Elf18 (300 nM; 30-90 min) can stimulate the production of H2O2 in Arabidopsis cells, but has no such effect in rice cells[1].
Elf18 (5 μM; 0-12 h) induces the expression of ELENA1 in 10-day-old wild-type Arabidopsis seedlings[2].
Elf18 (5 μM; 24 h) affects the expression of PR1 (pathogenesis related-gene 1) and PR2 (pathogenesis related-gene 2) in Arabidopsis plants with ELENA1 knockdown and overexpression[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Powder -80°C 2 years -20°C 1 year * In solvent : -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture)
Solvent & Solubility
H2O : ≥ 100 mg/mL (48.33 mM)
DMSO : 25 mg/mL (12.08 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
* "≥" 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.
