摘要:

通过SDS-PAGE 电泳对牛血清中纤维蛋白原检测方法进行研究,确定检测参数为分离胶浓度12.5%、交联度3%、浓缩胶浓度5%。结果表明,采用4℃温度条件下、21% 饱和硫酸铵溶液对牛血清中的纤维蛋白原进行分离,所得血清中纤维蛋白原的残留量仅为0.02473%。

Abstract:

Fibrinogen in bovine serum was determined using tricine-sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) method, and the optimum condition were obtained as follows: separation gel concentration 12.5%, cross linking degree 3% and the concentration of spacer gel 5%. Fibrinogen was separated from bovine serum using 21% ammonium sulfate precipitation at 4 ℃, and the fibrinogen residue in bovine serum was reduced to 0.02473%.

Key words: bovine serum, fibrinogen, determination, separation
