Activité biologique
Flagelin 22 (100 nM, 1 or 24 h) activates a gene that triggers immunity (PTI) and leads to reduced expression of growth-promoting hormone brassinolide (BR) biosynthesis in plants[2].
Flagelin 22 (10 μM, 4 h) regulates the release of ethylene reactive factor substrate in Arabidopsis MAP kinase 6 by ethylene signaling[3].

H2O : 100 mg/mL (44.00 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.

Protocole
One milliliter of the female gametophytes is added to 100 mL sterilized seawater containing 1 μM of Flagelin 22, flg15, flg14, and flg22D43A, respectively. Controls are sterilized seawater and 0.1% BSA in sterilized seawater. Gametophytes are grown at 10°C with a 24-h photoperiod at 50 μmol photons m-2 s-1. Sterilized seawater medium is provided with 0.2 mM KNO3, 0.02mM KH2PO4, and 1 μM of the four respective peptides and refreshed every week. The gametophytes are briefly blotted dry, and the fresh weight is measured after 40 days[1].
