  • 產(chǎn)品描述：
    人補體片斷4b(C4b)酶聯(lián)免疫試劑盒（CSB-E09302h）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿樣本中的C4b含量。C4b是補體系統(tǒng)經(jīng)典途徑和凝集素途徑激活過程產(chǎn)生的重要片段。補體系統(tǒng)在免疫防御等方面發(fā)揮關(guān)鍵作用。研究顯示，C4b可參與調(diào)理吞噬、免疫黏附等過程，其異常活動可能與多種免疫相關(guān)疾病發(fā)生發(fā)展有關(guān)，是免疫學(xué)研究重要靶點。試劑盒檢測范圍為15.6 ng/mL-1000 ng/mL，適用于科研領(lǐng)域中對補體系統(tǒng)功能的探索，例如在炎癥模型、免疫調(diào)節(jié)實驗或疾病機制研究中定量分析血清/血漿樣本的C4b表達動態(tài)，為揭示補體介導(dǎo)的生理病理過程提供可靠工具本品僅用于科研，不用于臨床診斷，產(chǎn)品具體參數(shù)及操作步驟詳見產(chǎn)品說明書。

靶點詳情

  • 功能：
    Non-enzymatic component of the C3 and C5 convertases and thus essential for the propagation of the classical complement pathway. Covalently binds to immunoglobulins and immune complexes and enhances the solubilization of immune aggregates and the clearance of IC through CR1 on erythrocytes. C4A isotype is responsible for effective binding to form amide bonds with immune aggregates or protein antigens, while C4B isotype catalyzes the transacylation of the thioester carbonyl group to form ester bonds with carbohydrate antigens.; Derived from proteolytic degradation of complement C4, C4a anaphylatoxin is a mediator of local inflammatory process. It induces the contraction of smooth muscle, increases vascular permeability and causes histamine release from mast cells and basophilic leukocytes.
  • 相關(guān)疾病：
    Systemic lupus erythematosus (SLE); Complement component 4B deficiency (C4BD)
  • 亞細胞定位：
    Secreted. Cell junction, synapse. Cell projection, axon. Cell projection, dendrite.
  • 組織特異性：
    Complement component C4 is expressed at highest levels in the liver, at moderate levels in the adrenal cortex, adrenal medulla, thyroid gland, and the kidney, and at lowest levels in the heart, ovary, small intestine, thymus, pancreas and spleen. The extr
