產品詳情

  • 產品描述：
    小鼠甘露糖結合凝集素相關絲氨酸蛋白酶2(MASP2)酶聯免疫試劑盒（CSB-EL013510MO）為競爭法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的MASP2含量。MASP2是一種血清蛋白酶，通過甘露糖結合凝集素激活補體系統，裂解C2和C4，形成C3轉化酶，是補體級聯中的關鍵步驟。其研究機制涉及MASP2的激活、裂解和補體系統的激活過程。試劑盒檢測范圍為125 pg/mL-8000 pg/mL，適用于免疫學、炎癥機制、補體系統功能等領域的基礎研究，如探索感染性疾病模型、自身免疫疾病動物實驗中MASP2的動態變化及其調控機制。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：
    Serum protease that plays an important role in the activation of the complement system via mannose-binding lectin. After activation by auto-catalytic cleavage it cleaves C2 and C4, leading to their activation and to the formation of C3 convertase.
  • 基因功能參考文獻：
    1. MASP-2 has an essential role in the mediation of cerebral ischemia-reperfusion injury. PMID: 27577570
    2. this study shows that MASP-2 contributes to the development of collagen Ab-induced arthritis PMID: 28739878
    3. We induced anti-myeloperoxidase vasculitis in mice and showed that neither MASP-2- nor properdin-deficient mice were protected, suggesting that alternative pathway activation does not require properdin or the lectin pathway. PMID: 27235854
    4. Mannan-binding lectin-associated serine protease 2 is critical for the development of renal ischemia reperfusion injury and mediates tissue injury in the absence of complement C4. PMID: 24868011
    5. Gene targeting of mouse TDP-43 negatively affects Masp2 expression. PMID: 24740308
    6. ALI in H5N1-infected mice was caused by excessive complement activation, as demonstrated by deposition of C3, C5b-9, and MBL-C in lung tissue, and by up-regulation of MBL-associated serine protease-2 and the complement receptors C3aR and C5aR. PMID: 23526211
    7. study corroborates the essential function of MASP-2 in the lectin pathway and highlights the importance of mannan-binding lectin-independent lectin pathway activation in the host defense against pneumococci PMID: 22792067
    8. Targeting of mannan-binding lectin-associated serine protease-2 confers protection from myocardial and gastrointestinal ischemia/reperfusion injury. PMID: 21502512
    9. Highly conserved intron sequences. Restricted expression contrasts with the ubiquitous expression of neighboring genes. PMID: 15672593
    10. Recombinant protein of masp2 was made and purified. PMID: 15826378
    11. MASP-2 is essential for the activation of C4 and sMAP plays a regulatory role in the activation of the lectin pathway. PMID: 17142762
