일반 설명
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. L-Histidine is an essential amino acid, widely present at the active sites of enzymes. It binds to metal ions and may aid in the transport of copper. It also plays an important role for the binding of heme groups, macromolecules and phosphate groups in the binding sites of proteins.
애플리케이션
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
생화학적/생리학적 작용
Precursor of histamine by action of histidine decarboxylase.
분석 메모
These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.
기타 정보
This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

Ca(2+) signaling regulates cell function. This is subject to modulation by H(+) ions that are universal end-products of metabolism. Due to slow diffusion and common buffers, changes in cytoplasmic [Ca(2+)] ([Ca(2+)]i) or [H(+)] ([H(+)]i) can become compartmentalized, leading potentially to
