Application

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。

General description

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。

Dietary antioxidants play an important role in preventing oxidative stress. Whether animals in search of food or brood sites are able to judge the antioxidant content, and if so actively seek out resources with enriched antioxidant content, remains unclear. We

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

Cell-cycle inhibition has yet to offer a generally effective approach to cancer treatment, but a full evaluation of different combinations of cell-cycle inhibitors has not been evaluated. Cyclin A2, a core component of the cell cycle, is often aberrantly expressed

Increases in plasma B-type natriuretic peptide (BNP) concentrations in those with acutely decompensated heart failure (ADHF) has been mainly attributed to an increase in NPPB gene transcription. Recently, proBNP glycosylation has emerged as a potential regulatory mechanism in the production
