產品詳情

  • 產品描述：
    牛α2巨球蛋白(A2M)酶聯免疫試劑盒（CSB-EL001004BO）為競爭法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的A2M含量。A2M即α?-巨球蛋白，是血漿中一種多功能糖蛋白。它能抑制多種蛋白水解酶活性，參與細胞的生長、修復等過程。在研究機制上，主要關注其對蛋白酶的捕獲作用、與細胞表面受體的相互作用，以及在疾病發生發展中所扮演的角色。試劑盒檢測范圍為0.312 μg/mL- 20 μg/mL，適用于科研場景中牛類動物模型的炎癥機制研究、免疫調控分析或蛋白酶活性相關疾病模型的分子機制探索本品僅用于科研，不用于臨床診斷，產品具體參數及操作步驟詳見產品說明書。

靶點詳情

  • 功能：
    Is able to inhibit all four classes of proteinases by a unique 'trapping' mechanism. This protein has a peptide stretch, called the 'bait region' which contains specific cleavage sites for different proteinases. When a proteinase cleaves the bait region, a conformational change is induced in the protein which traps the proteinase. The entrapped enzyme remains active against low molecular weight substrates (activity against high molecular weight substrates is greatly reduced). Following cleavage in the bait region a thioester bond is hydrolyzed and mediates the covalent binding of the protein to the proteinase.
