Description

Flagelin 22 (Flagellin 22), a fragment of bacterial flagellin, is an effective elicitor in both plants and algae[1][2][3].

In Vitro

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].

Cell Assay
[1]

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].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
