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。抗坏血酸是一种强大的抗氧化剂，广泛用于药物制剂中。经证其对衰老相关疾病（如癌症、动脉粥样硬化、眼病、神经退行性疾病等）具有有益作用。它主要参与胶原蛋白的形成和维持。饮食长期缺乏抗坏血酸会导致坏血病。

应用

抗坏血酸可用制药参考标准品，通过亲水作用色谱定量药物制剂中的分析物。

生化/生理作用

抗坏血酸，也称为维生素C，是由植物和一些动物物种（不包括人类和其他灵长类动物）产生的六碳内酯。抗坏血酸可作为多种酶的酶促辅助因子，可用作单加氧酶和双加氧酶的电子供体。抗坏血酸还起到强力抗氧化剂的作用，特别是对活性氧。

分析说明

这些二级标准品为USP、EP（PhEur）和BP等主要标准品提供了多种可追溯性。

其他说明

该认证参考物质（CRM）根据ISO 17034 和 ISO/IEC 17025进行生产和认证。有关此CRM使用的所有信息均可在分析证书上找到。

Oxidative stress and low-grade systemic inflammation may contribute to the pathogenesis of obesity-induced comorbidities, including nonalcoholic fatty liver disease. Increasing intake of dietary antioxidants might be beneficial, but there are few data in obese children. To examine the effect of

Efficient definitive endoderm induction from mouse embryonic stem cell adherent cultures: a rapid screening model for differentiation studies.

Stem cell research, 12(1), 166-177 (2013-11-19)

Definitive endoderm (DE) differentiation from mouse embryonic stem cell (mESC) monolayer cultures has been limited by poor cell survival or low efficiency. Recently, a combination of TGFβ and Wnt activation with BMP inhibition improved DE induction in embryoid bodies cultured
