Abstract
  1. Electrophoresis of extracts of turkey spermatozoa for lactate dehydrogenase activity revealed the usual five tissue LDHs (LDH-1 to LDH-5). 2. The presence of LDH-X (the spermatozoan-specific isozyme) was not obvious. 3. Only one band was present on electrophoresis of fowl spermatozoan extracts and it coincided with LDH-1 (heart type). 4. Kinetic investigations, the use of inhibitors and the heat-stability test confirmed that the fowl spermatozoan LDH was probably LDH-1 and not LDH-X.
摘要
  1. 对火鸡精子提取物进行乳酸脱氢酶活性电泳分析,结果显示出常见的五种组织乳酸脱氢酶(LDH-1至LDH-5)。2. 精子特异性同工酶LDH-X并不明显。3. 禽类精子提取物电泳时仅出现一条带,且与LDH-1(心脏型)一致。4. 动力学研究、抑制剂的使用以及热稳定性测试证实,禽类精子乳酸脱氢酶可能是LDH-1而非LDH-X。
