Application
Ammonium acetate solution can be used to study molecular biology, biological buffers, reagents and DNA and RNA purification. Ammonium acetate solution has been used to study pharmacokinetic analysis of α and β epimers of glycyrrhetinic acid in rat plasma. Ammonium acetate solution has also been used in a study to develop a method for the simultaneous determination of aristolochic acids A and B in some Chinese herbals and traditional Chinese patent medicines.

Other Notes
Alternative to sodium acetate in ethanol precipitation of nucleic acids. Prevents precipitation of deoxyribonucleoside triphosphates.; Useful for removal of untreated triphosphates from the products of reverse transcriptase, DNA polymerase or terminal polymerase-catalyzed reactions1.
Application
Ammonium acetate can be used to study molecular biology, reagents, protein structural analysis, proteomics and x-ray crystallography. Ammonium acetate has been used in a study to develop an easy, rapid, low-cost and effective cetyltrimethylammonium bromide (CTAB)-ammonium acetate method for high-quality RNA isolation from polysaccharide- and polyphenol-rich cotton tissues. Ammonium acetate has also been used in a study to develop and validate a simple and rapid high-performance liquid chromatography-electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS) method for the determination of 4-p-anisamidobutyric acid (ABA; or N-anysoyl-γ-aminobutiryc acid, N-anisoyl-GABA), a major active metabolite of aniracetam, in human plasma.

Other Notes
Elution buffer in separation of proteins by gel filtration, ammonium acetate is volatile and can be removed during lyophilization1.
Application
Ammonium acetate can be used to study x-ray crystallography, optimization reagents, protein structural analysis and proteomics. Ammonium acetate has been used in a study to develop a novel and simple high-performance liquid chromatography method for the simultaneous determination of two selective serotonin reuptake inhibitors and two serotonin-norepinephrine reuptake inhibitors in alternative samples of toxicological interest such as hair, nail clippings, and cerebrospinal fluid.
