Biochem/physiol Actions 抑制神经元一氧化氮合成酶 (nNOS)。与 DNA 结合并使其沉淀,可用于纯化 DNA 结合蛋白。刺激 T4 多核苷酸激酶的活性。 Caution 如果需要无菌溶液,则应采用无菌过滤而非高压灭菌。时间一长,亚精胺将发生脱氨基作用;溶液应采用冷冻保存。通常需要配制新溶液。 包装 1, 5 g in glass bottle
Biochem/physiol Actions Inhibits neuronal nitric oxide synthase (nNOS). Binds and precipitates DNA, may be used for purification of DNA binding proteins. Stimulates T4 polynucleotide kinase activity. Caution Solutions should be sterile-filtered, not autoclaved, if sterile solution is necessary. Spermidine deaminates with time; solutions should be stored frozen. Prepare new solutions frequently.
