3809-05-9/E-086-1ML 3-epi-25-Hydroxyvitamin D3/3-表25-羟基维生素D3标准溶液
50 ug/mL in Ethanol | Certified Reference Material/E-086-1ML
A Certified Spiking Solution® of 3-epi-25-Hydroxyvitamin D3, the epi isomer of the prohormone 25-hydroxyvitamin D3. The presence of 3-epi-25-hydroxyvitamin D3 can affect accurate quantitation of 25-hydroxyvitamin D3 levels by most routine LC-MS/MS methods and to an unknown extent in immuno- and protein binding assays. This solution standard is suitable for critical quantitative applications in research and clinical environments including: for use in preparation of controls and calibrators for LC/UV and LC-MS/MS assays; as system tuning/suitability standards; linearity verification; internal proficiency testing; and for OEM use in preparation of reagents, development of assays and instrument IQ/OQ.3-epi-25-Hydroxyvitamin D3
3-epi-25-羟基维生素D3的认证加标溶液®，它是25-羟基维生素D3前激素的epi异构体。3-epi-25-羟基维生素D3的存在会影响大多数常规LC-MS/MS方法对25-羟基维生素D3水平的准确定量，在免疫和蛋白质结合测定中的影响程度尚不清楚。该溶液标准适用于研究和临床环境中的关键定量应用，包括：用于制备LC/UV和LC-MS/MS测定的对照品和校准品；作为系统调整/适用性标准；线性验证；内部能力测试；以及用于OEM制备试剂、开发检测和仪器IQ/OQ。/3-表25-羟基维生素D3标准溶液
