Abstract
A DNA polymerase was isolated from bull spermatozoa by differential centrifugation, ultrafiltration and gel filtration. Its apparent molecular weight and synthetic template utilization resemble that of DNA polymerase gamma. Chemical and enzymic fractionation of bull spermatozoa indicate that the enzyme is most probably located in the nucleus.
摘要
通过差速离心、超滤和凝胶过滤从公牛精子中分离出一种DNA聚合酶。其表观分子量和合成模板利用率与DNA聚合酶γ相似。对公牛精子进行化学和酶学分级分离表明，该酶很可能位于细胞核中。
