| 2. | The result shows as follows : one is that hog cu , zn - sod has no isozymes and it contains the same two subunits , with molecular masses of 32112 daltons . the other is that the polymorphism of the cu , zn - sod from hog blood is caused by polymerization and conformational isomers 结果表明:猪血只含一种cu , zn - sod类型,其分子量为32112 ,有两个相同的亚基构成,本文所测得的亚基约为16293 ,约为分子量的一半。 |
