  • 产品描述：

        高敏C反应蛋白（high-sensitivity C-reactive protein，hs-CRP），是一种由肝脏合成的血浆蛋白，主要是响应机体内的炎症和损伤。hs-CRP的含量水平通常很低，但在炎症、感染、心血管疾病等情况下，其含量会显著升高。因此，hs-CRP测定可以用于评估心血管疾病风险、监测炎症进程等。

  • 最新研究进展：
    hs-CRP是一种急性反应蛋白，它可以在炎症、感染和损伤等情况下升高，通常用于衡量炎症的程度和预测心血管疾病的风险。最近的研究表明，hs-CRP水平还可能与某些癌症的发生和发展有关。
  • 功能：
    Displays several functions associated with host defense: it promotes agglutination, bacterial capsular swelling, phagocytosis and complement fixation through its calcium-dependent binding to phosphorylcholine. Can interact with DNA and histones and may scavenge nuclear material released from damaged circulating cells.
