说明

一般描述

Ammonium sulfate is naturally present as a rare mineral mascagnite in volcanic fumaroles and due to coal fires in some dumps.

应用

Ammonium sulfate has been used:

to prepare mobile phase A for hydrophobic interaction chromatography (HIC)
as reference material for the thermal decomposition of NH₄NO₃ (S1–S6) thermal decomposition to N₂O (S1-N₂O–S6-N₂O)
to prepare the stock solution for M63 medium
as a reagent in molecular biology and chromatography
in the precipitation and fractionation of proteins
in the purification of antibodies
for the crystallographic analysis of nucleic acids and proteins
in high-performance liquid chromatography (HPLC) analysis of proteins, such as in hydrophobic interaction chromatography
for Sepharose chromatography of tRNAs using reverse salt gradients
in long PCR buffer, in PCR lysis solution, and second-strand cDNA synthesis
HPLC analysis of phospholipids

生化/生理作用

Ammonium sulfate is an inorganic salt, which is mostly used as a soil fertilizer. It is also used as a flame retardant since it elevates the combustion temperature of the material and lowers maximum weight loss rates. This leads to an upsurge in the production of residue or char.

其他说明

由于其溶解性和有效性，其作为最常用的盐用于：蛋白质的分级沉淀[1];蛋白质结晶[2];使用反盐梯度对tRNA进行琼脂糖^®色谱分析[3]。
