说明

應用

• Discovery of contaminants with antagonistic activity against retinoic acid receptor in house dust.: This research explores environmental contaminants in house dust that exhibit antagonistic activities against retinoic acid receptors, with analytical methodologies including the use of phosphate standard solutions for quantification and validation (Jia Y et al., 2022).
• Activation of a membrane-associated phosphatidylinositol kinase through tyrosine-protein phosphorylation by naphthoquinones and orthovanadate.: Investigating the biochemical pathways activated by tyrosine phosphorylation, this study utilizes phosphate standards to monitor enzyme activity, offering implications for drug development and molecular biology (Chen YX et al., 1990).

分析報告

浓度     β (PO₄³⁻)：990 - 1010 mg/l
测定方法：银量滴定法。
该溶液的含量是用氢氧化钠标准溶液（货号1.09141）测定的，该标准溶液是用容量标准邻苯二甲酸氢钾（货号1.02400）标定的。扩展测量不确定度为± 0.4 %（k=2，覆盖因子为95%覆盖率）。认证值可通过体积标准邻苯二甲酸氢钾追溯至一级标准品NIST SRM 84L（NIST：美国国家标准技术研究院）。该过程由德国Darmstadt Merck KGaA公司认可的校准实验室根据DINDIN EN/ISO 17025进行测定。
