Methods The purification procedure of human factor ⅶ from Cohn fraction ⅲ precipitate involves dissolving fraction ⅲ, absorbing factor ⅶ onto barium citrate and eluting, ammonium sulfate fractionation and DEAE-Sepharose Fast Flow ion exchange chromatography, and Sephadex G-100 gel filtration chromatography. 方法将组分Ⅲ沉淀溶解,经柠檬酸钡吸附、洗脱、硫酸铵沉淀、2次DEAE-sepharoseFastFlow离子交换层析和SephadexG-100凝胶过滤纯化人FⅦ。
Preparation of Nanometer Crystalloid Barium Titanate Powder by Improved Citrate Sol-Gel Method 改进的柠檬酸盐溶胶-凝胶法制备四方相纳米尺寸钛酸钡粉体
Two adsorption methods with Mg ( OH) 2 or barium citrate to prepare crude prothrombin from pig blood were compared, adsorption. It was showed that the yield and purity of the barium citrate process were higher. 通过对两种猪凝血酶原粗品制备方法(氢氧化镁吸附法和柠檬酸钡吸附法)的比较研究,发现钡法工艺的得率和纯度较高。
The technology including polyethylene glycol precipitation, barium citrate adsorption and DEAE-cellulose chromatography were applied to prepare porcine factor V. Porcine factor V was identified by SDS-PAGE. 采用聚乙二醇沉淀、柠檬酸钡吸附、DEAE纤维素离子交换层析等方法,制备了猪凝血因子V。
By investigating initial component and condition, Cobalt ferrite and Barium ferrite were synthesized by citrate Sol-Gel method. 通过对初始组分及反应条件的研究,采用柠檬酸溶胶凝胶技术成功地制备了纳米钴铁氧体与钡铁氧体;
