General description

Triethylammonium acetate, also known as TEAA, is a volatile buffer widely utilized as a buffer in various biochemical and biological applications, particularly in peptide and proteomics research. It is a common choice for ion-pairing reagent in the chromatographic separation of oligonucleotides and plays a key role in buffer solutions for oligonucleotide synthesis and purification.

Application

Triethylammonium acetate has been used:
  • as a buffer in proteomics studies
  • as a component of the mobile phase to separate nucleotide sugars
  • as a buffer for the separation of glycopeptides in proteomics research

Features and Benefits

  • Suitable for Biological and Biochemical Research
  • Ready available solution reduce the need for preparation time
