对培养2至7天分六阶段抽样的尖尾藻细胞(Oxyrrhis marina)进行乳酸脱氢酶同工酶琼脂糖凝胶电泳分析,结果表明,全部样品中乳酸脱氢酶同工酶均呈现三种不同分子形式的表型特征。随电泳迁移率的增大,由阴极趋于阳极端依次为LDH_3,LDH_2,LDH_1,采用分光光度比色定量法,于波长560nm测得各同工酶组份相对百分含量见表1。LDH_3同工酶在培养2至7天的全过程中酶活性水平始终保持高于LDH_1和LDH_2的水平。在培养第四天山现最高值。 Lactate dehydrogenase isoenzyme agarose gel electrophoresis analysis of six-section sampled Oxyrrhis marina cultured for 2 to 7 days showed that the lactate dehydrogenase isoenzymes of all the samples showed three Different molecular forms of phenotypic characteristics. With the increase of electrophoretic mobility, the cathode tends to the anode followed by LDH_3, LDH_2, LDH_1, the use of spectrophotometric colorimetric method, measured at a wavelength of 560nm relative isozyme components in Table 1. The enzyme activity of LDH_3 isoenzyme remained higher than that of LDH_1 and LDH_2 throughout the course of 2 to 7 days. In the fourth day of training the highest mountain value.
