General description

Triethanolamine (TEA) is a quaternary ammonium compound commonly used as a buffer and emulsifier.

Application

Triethanolamine can be used as:
  • A nitrogen precursor in the preparation of carbon dot derived nanomaterials.
  • A cross-linking agent in the synthesis of methylaluminoxane pre-catalysts applicable in the polymerization of ethylene.
  • A reducing agent to synthesize Ag nanoparticles of biological importance.

Phosphorylation of heptahelical receptors is thought to regulate G protein signaling, receptor endocytosis, and non-canonical signaling via recruitment of β-arrestins. We investigated chemokine receptor functionality under phosphorylation-deficient and β-arrestin-deficient conditions by studying interneuron migration in the embryonic cortex. This process
