Diethanolamine (DEA) is a polyfunctional product that is a secondary amine and a diol and acts as a weak base. Diethanolamine buffer (10 mM diethanolamine 0.5 mM MgCl2 pH 9.5) is frequently used in colorimetric assays (ELISA) using p-nitrophenyl phosphate (PNPP sc-3720) substrate and diethanolamine buffer.

Potent, high affinity apelin receptor agonist (IC50 = 0.27 nM; Kd = 0.51 nM). Exhibits no binding GPR15 and GPR25. Activates the PI3K/AKT pathway and promotes self-renewal of hESCs via cell-cycle progression and protein translation. Also potentiates the TGFβ pathway, priming hESCs toward the endoderm lineage. Stimulates angiogenesis in HUVEC cells. Relaxes mouse aortic vessels. Functions as an anorexigenic hormone through activation of the AVP and CRH neurons in the PVN.
