产品详细信息

详细说明 (English)

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.
