C12-iE-DAP Unit size Cat. code Docs Qty Price
NOD1 agonist
1 mg


C12-iE-DAP is an acylated derivative of the iE-DAP dipeptide (γ-D-Glu-mDAP) present in the peptidoglycan (PGN) of Gram-negative bacilli and particular Gram-positive bacteria such as Bacillus subtilis and Listeria monocytogenes [1].

Similarly to iE-DAP, C12-iE-DAP is recognized by the intracellular sensor NOD1 (CARD4), which results in a signaling cascade involving the serine/threonine RIP2 (RICK, CARDIAK) kinase and IKK, and leading to NF-κB activation and the inflammatory cytokines production such as TNF-α and IL-6 [2].
C12-iE-DAP stimulates NOD1 at concentrations 100- to 1000-fold lower than iE-DAP.

C12-iE-DAP was generated by addition of a lauroyl (C12) group to the glutamic residue of iE-DAP. 
C12-iE-DAP provided by InvivoGen is chemically synthesized and tested using HEK-Blue™ NOD1.


Note: C12-iE-DAP is a mixture of Lauroyl-g-D-Glu-D-mDAP and Lauroyl-g-D-Glu-L-mDAP.
