一般描述

用于质量控制的制药二级标准品,为制药实验室和制造商制备内部工作标准品提供了一种方便、高性价比的替代方案。甲醇是极性有机溶剂,在化学、生物化学和分子生物学领域广泛使用。它是HPLC和质谱(MS)的常用溶剂,适用小分子和生物分子(如寡核苷酸和蛋白质)。甲醇还用于高效毛细管电泳。甲醇的工业应用包括生产甲醛、有机酸甲酯和无机酸甲酯。甲醇可用作聚合物的溶剂和溶剂佐剂,也可用作硝酸纤维素塑料的软化剂。

应用

这些二级标准品是经过检验的认证标准物质(CRM)。它们适用于多种分析应用,包括但不限于药物释放测试、药物的定性和定量分析方法开发、食品和饮料质量控制检测以及其他校准需求。

Macrophages populate the steady-state myocardium. Previously, all macrophages were thought to arise from monocytes; however, it emerged that, in several organs, tissue-resident macrophages may self-maintain through local proliferation. Our aim was to study the contribution of monocytes to cardiac-resident macrophages
