牛红细胞SOD提取过程中去血红蛋白新方法的研究

STudy on a New Way of Removing Hemoglobin in the Prosess or Extracting SOD from Red Blood Cells of Cow

以牛血为原料提取ＳＯＤ，在提取工艺中采取去血红蛋白的新方法，效果很好。去血红蛋白后提取液中的ＳＯＤ活力为４２００００Ｕ／Ｌ牛血，浓缩后制成冻干粉，其ＳＯＤ比活力为６５００Ｕ／ｍｇ蛋白质。

In this paper,a new and effective way of removing hemoglobin is advanced when cowblood is used as a raw material to extract SOD.The vitality of the SOD in the hemoglobin-removed liquid is 420,000U per litre cowblood,and The specific acfivity of the SOD is 6500U per milligram protein after the liquid is condensed and made into the freezed-and-dried powder.
