Principle of ammonium salt precipitation
WebAmmonium sulfate is commonly used due to its high solubility that allows salt solutions with high ionic strength. At sufficiently high ionic strength, the protein will be almost completely precipitated from the solution. Differential precipitation of proteins by ammonium sulfate is one of the most widely used preliminary purification procedures. WebThe simplest way to achieve this is to dialyse the solution. As shown in the diagram, the enzyme solution is placed in a bag of selectively permeable membrane (e.g. cellophane), …

WebJul 28, 2024 · The precipitation protocol is based the electrostatic interactions between cations of salt and phosphates of DNA backbones. In fact, DNA is a double helix of two negatively charged phosphate-sugar backbones, along which nucleic acids are bonded, so positively charged ions such as calcium or sodium will be attracted to its backbone.
