    • An improved plasmid for the production of superoxide dismutase which upon introduction into a host containing the thermolabile repressor C.sub.I renders the host capable of effecting expression of a gene encoding superoxide dismutase. The plasmid which includes in 5' to 3' order the following: the promoter and operator P.sub.L O.sub.L from lambda bacteriophage; the N utilization site; a first restriction enzyme site permitting replacement of the ribosomal binding site which follows thereafter; a ribosomal binding site; an ATG initiation codon; a second restriction enzyme site; a gene encoding superoxide dismutase; an origin of replication and a gene associated with a selectable or identifiable phenotypic trait manifested when the plasmid is present in the host. The distance between the 3' end of P.sub.L O.sub.L and the 5' end of the N utilization site is less than about 80 base pairs. The distance between the 3' end of the N utilization site and the 5' end of the ribosomal binding site is less than about 300 base pairs.Host vector systems have been constructed from these plasmids and used to produce human superoxide dismutase and analogs thereof. Such SOD or analogs may be used to catalyze the reduction of superoxide radicals, reduce reperfusion injury, prolong the survival time of isolated organs and reduce spinal cord injury.
    • 用于生产超氧化物歧化酶的改良质粒,其在引入含有不耐热阻遏物CI的宿主中时,使宿主能够实现编码超氧化物歧化酶的基因的表达。 包含5'至3'的质粒命名如下:来自λ噬菌体的启动子和操纵子PLOL; N利用场所; 第一限制性内切酶位点,其允许置换随后的核糖体结合位点; 核糖体结合位点; ATG起始密码子; 第二限制酶位点; 编码超氧化物歧化酶的基因; 复制起点和当质粒存在于宿主中时显示的与可选择或可鉴定的表型性状相关的基因。 PLOL的3'端与N利用位点的5'端之间的距离小于约80个碱基对。 N利用位点的3'末端与核糖体结合位点的5'末端之间的距离小于约300个碱基对。 宿主载体系统已经由这些质粒构建并用于产生人超氧化物歧化酶及其类似物。 这种SOD或类似物可用于催化超氧自由基的减少,减少再灌注损伤,延长分离器官的存活时间并减少脊髓损伤。

    • A method is provided for recovering a purified animal growth hormone or a polypeptide analog thereof having substantially the same amino acid sequence as, and the biological activity of, the corresponding naturally-occurring animal growth hormone from a bacterial cell in which the animal growth hormone or polypeptide analog has been produced by means of expression of a plasmid encoding the hormone or polypeptide analog which comprises: (a) disrupting the cell wall of the bacterial cell in a buffered neutral pH solution so as to produce a lysate containing precipitated hormone or polypeptide analog; (b) recovering the resulting precipitated hormone or polypeptide analog; (c) suspending the precipitated hormone or polypeptide analog so recovered in distilled water; (d) treating the resulting precipitate-containing suspension with a sodium hydroxide solution having an alkaline pH of about 11.8 so as to solubilize the precipitate and thus the hormone or polypeptide analog contained therein; (e) separating the solubilized hormone or polypeptide analog from other soluble components by gel filtration chromatography; and (f) subjecting the hormone or polypeptide analog thus separated to ion exchange chromatography to purify the hormone or analog and thereby recover purified hormone or polypeptide analog.
