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.

Other Notes

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

Hepatitis B virus core-antigen (capsid protein) and e-antigen (an immune regulator) have almost complete sequence identity, yet the dimeric proteins (termed Cp149d and Cp(-10)149d , respectively) adopt quite distinct quaternary structures.
