产品描述:本试剂盒用于定量检测人血清和血浆中的维生素A(VA)水平,该脂溶性维生素在视觉功能、免疫调节及细胞分化中发挥重要作用,其精准检测可为营养学研究或代谢机制分析提供数据支持。产品采用竞争法酶联免疫吸附原理,通过预包被VA抗原与样本中目标物质竞争结合特异性抗体,最终在450nm波长下测定吸光度值实现定量分析,全程检测仅需约3小时。其线性检测范围为0.625-10 ng/mL,最低检测灵敏度达0.312 ng/mL,适用于微量样本分析。操作时需注意将血清/血浆样本离心去除颗粒物,4℃保存需在24小时内完成检测,长期保存建议-20℃分装且避免反复冻融。该产品可广泛应用于科研领域,如膳食干预研究中VA代谢动态监测、疾病模型维生素缺乏状态评估,或药理学研究中营养补充剂的效果验证,实验人员可通过标准曲线精准计算样本浓度值,为生命科学基础研究提供高效便捷的检测工具。
