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。L-组氨酸是一种必需氨基酸,广泛存在于酶的活性部位。它可与金属离子结合,并可能有助于铜的运输。它还在蛋白质结合位点上对血红素基团、大分子和磷酸基团的结合起着重要作用。
应用
这些二级标准品是合格的认证标准物质(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。
生化/生理作用
组胺的前体,经组氨酸脱羧酶作用可生成组胺。
分析说明
These secondary standards offer multi-traceability to the USP and EP (PhEur) primary standards, where they are available.

Engineered affibody molecules can be used for high contrast in vivo molecular imaging. Extending a recombinantly produced HER2 binding affibody molecule with a hexa-histidine tag allows for convenient purification by immobilized metal-ion affinity chromatography and labeling with [(99m)Tc(CO)3](+) but increases

Ruminal bacterial community composition (BCC) and its associations with ruminal fermentation measures were studied in dairy heifers challenged with combinations of grain, fructose, and histidine in a partial factorial study. Holstein-Friesian heifers (n=30) were randomly allocated to 5 triticale grain-based
