Abstract

Alkaline phosphatase, excreted by Neurospora crassa preg (c) and purified to apparent homogeneity by 7.5% PAGE, did not show DNAase activity and removed the terminal 5'-phosphate group from plasmid Bluescript M13(+) linearized with EcoRI. The preg (c) strain may therefore replace other sources of alkaline phosphatase for use in dephosphorylating linearized plasmidial DNA in cloning experiments.

摘要

碱性磷酸酶由粗糙脉孢菌 preg (c) 分泌，并通过 7.5%PAGE 纯化至明显均一性，不显示 DNAase 活性，并从用 EcoRI 线性化的质粒 Bluescript M13(+) 中去除 5'-末端磷酸基团。因此，preg (c) 菌株可能替代其他来源的碱性磷酸酶，用于在克隆实验中使线性化的质粒 DNA 去磷酸化。
