產(chǎn)品詳情

  • 產(chǎn)品描述：
    人幾丁質酶3樣蛋白2(CHI3L2)酶聯(lián)免疫試劑盒（CSB-EL005347HU）為雙抗夾心法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的CHI3L2含量。CHI3L2是一種糖基水解酶家族成員，缺乏酶活性，通過結合多糖和細胞表面受體調控炎癥、組織重塑和腫瘤微環(huán)境。在關節(jié)炎、纖維化疾病和惡性腫瘤中高表達，是疾病進展的生物標志物和潛在治療靶點。試劑盒檢測范圍為0.78 ng/ml-50 ng/ml，該產(chǎn)品可為炎癥性疾病機制研究、纖維化模型評估或腫瘤微環(huán)境分析提供關鍵生物標志物檢測支持，特別適用于基礎醫(yī)學、免疫學及分子病理學領域的體外樣本檢測，幫助研究者探索CHI3L2在疾病發(fā)生發(fā)展中的調控作用。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。

    Intra-assay Precision (Precision within an assay): CV%<8%

    Three samples of known concentration were tested twenty times on one plate to assess.

    Inter-assay Precision (Precision between assays): CV%<10%

    Three samples of known concentration were tested in twenty assays to assess.

  • 線性度：

    To assess the linearity of the assay, samples were spiked with high concentrations of human CHI3L2 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

靶點詳情

  • 功能：
    Lectin that binds chitooligosaccharides and other glycans with high affinity, but not heparin. Has no chitinase activity.
  • 基因功能參考文獻：
    1. This study shown that CHI3L2 is regulated differently in healthy and late onset Alzheimer"s disease brain depending on the sex. PMID: 27653898
    2. Structural analysis demonstrates that YKL-39 interacts with chitooligosaccharides through hydrogen bonds and hydrophobic interactions. Thermodynamic analysis indicates that binding of chitooligosaccharide to YKL-39 is mainly driven by enthalpy. PMID: 25477513
    3. These data suggest that hYKL-39 is a novel growth and differentiation factor involved in cartilage homeostasis. PMID: 23291184
    4. YKL-39 possesses a chitinase-like fold, but lacks key active-site residues required for catalysis. PMID: 22742450
    5. ERK1/2 phosphorylation by CHI3L2 inhibits cell mitogenesis and proliferation. PMID: 22211103
