Description

Biochem/physiol Actions

Ammonium acetate can be used in x-ray crystallography, optimization reagents, protein structural analysis, and proteomics. It can also be used in a study to develop a novel and simple high-performance liquid chromatography (HPLC) 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.

Other Notes

Elution buffer in separation of proteins by gel filtration, ammonium acetate is volatile and can be removed during lyophilization.
