Ammonium Sulfate, MP Biomedicals™

Description

Ammonium Sulfate, ltra Pure Grade, ≥99%, White Crystalline Powder

• It is a widely used reagent in molecular biology and chromatography.
• It is useful in the isolation and purification of enzymes and proteins.
• It is used for the precipitation or fractionation of proteins or for purification of antibodies.
• It is also useful for crystallographic analysis of nucleic acids and proteins.
• It is also widely used in HPLC of proteins, such as in hydrophobic interaction chromatography.
• It is used in long PCR buffer, in PCR lysis solution, and in secondstrand cDNA synthesis.
• it is used for the HPLC analysis of phospholipids.
• Ammonium sulfate is an inorganic salt prepared by treating ammonia with sulfuric acid.
• Ammonium sulfate decomposes upon heating above 250°C, forming ammonium bisulfate.
• Heating at higher temperatures results in decomposition into ammonia, nitrogen, sulfur dioxide, and water.
• Ammonium sulfate forms many double salts (ammonium metal sulfates) when its solution is mixed with equimolar solutions of metal sulfates and the solution is slowly evaporated.
• Such double metal sulfates include ammonium cobaltous sulfate, ferric ammonium sulfate, ammonium nickel sulfate and ammonium cerous sulfat
