用薄层聚丙烯酰胺凝胶等电聚焦电泳测得该酶的等电点为3.85和4.35；
Its isoelectric points are 3.85 and 4.35, determined by iso-eletric focusing electrophoresis.
定量后，分别进行一维等电聚焦分离和二维聚丙烯酰胺凝胶电泳分离。
After quantification, the protein samples were separated by isoelectric focusing electrophoresis and then by SDS-PAGE.
SDS聚丙烯酰胺凝胶电泳测定分子量为64,000。等电聚焦电泳测得等电点在4.2左右。
Its molecular weight is 64,000 and isoelectric point around pH 4.2 as determined by SDS-PAGE and isoelectric focusing analysis respectively.
