产品描述：人尾加压素Ⅱ酶联免疫试剂盒为双抗夹心法ELISA试剂盒，定量检测血清、唾液、脑脊液（CSF）、组织匀浆样本中的UTS2含量。UTS2即尾加压素2，是目前所知的最强的缩血管活性肽。其作用机制复杂，可与尾加压素受体结合，调控细胞增殖、凋亡等，在心血管、神经等系统有重要作用。当前对其在疾病如高血压、心衰等发病机制中的研究较多。试剂盒检测范围为0.312 ng/mL-20 ng/mL，本试剂盒通过高特异性抗体实现目标蛋白的精准捕获与信号放大，适用于科研领域中对Urotensin II表达水平的研究，例如心血管疾病机制探索、神经系统功能分析或代谢紊乱相关模型的生物标志物检测。为研究Urotensin II在体液或组织中的动态变化、药物干预效果评估等提供可靠工具。本品仅用于科研，不用于临床诊断，产品具体参数及操作步骤详见产品说明书。
