Application
Ammonium citrate dibasic is generally used as a component of matrix solution in matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry analysis. It can also be used as both the carbon and nitrogen source to synthesize fluorescent nitrogen-doped carbon nanoparticles (CNPs).

Oligonucleotides synthesized on a montmorillonite catalyst were analyzed directly. By mixing the catalyst with a matrix (2,4,6-trihydroxyacetophenone or 6-aza-2-thiothymine) and dibasic ammonium citrate, higher molecular weight products were detected compared with "classical" methods such as gel electrophoresis and HPLC with

The reversibility of ubiquitination by the action of deubiquitinating enzymes (DUBs) serves as an important regulatory layer within the ubiquitin system. Approximately 100 DUBs are encoded by the human genome, and many have been implicated with pathologies, including neurodegeneration and
