Tetrasodium Pyrophosphate → Calcium Pyrophosphate Dihydrate

関与物質

反応手順

An aqueous calcium chloride solution and an aqueous sodium pyrophosphate solution were mixed together so that the calcium/phosphorus atomic ratio became 1:1, and the mixture was allowed to stand for a whole day to form calcium diphosphate dihydrate (Ca2P2O7.2H2O) crystals, which were then filtered off. The thus prepared material was packed into a column in the same manner as in Example 1, and a mixed sample of serum albumin, lysozyme and cytochrome c was chromatographed thereon. As a result the serum albumin flowed through the column without being retained therein, while the lysozyme and cytochrome c were retained therein.
