產品詳情

  • 產品描述：
    小鼠β氨基己糖苷酶A(β-Hex A)酶聯免疫試劑盒（CSB-E04818m）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HEXA含量。HEXA是一種溶酶體酶，負責分解GM2神經節苷脂，維持細胞內環境穩定。其突變會導致GM2神經節苷脂在細胞內積累，引發泰薩二氏病等疾病。研究HEXA的機制，旨在開發治療相關遺傳性神經退行性疾病的藥物。試劑盒檢測范圍為3.12 μU/mL-200 μU/mL，適用于研究β-Hex A在代謝性疾病模型小鼠中的表達調控、基因敲除/過表達動物模型的酶活性驗證，以及藥物干預或病理條件下溶酶體功能的評估等科研場景。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。

    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 mouse β-Hex A 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：
    Hydrolyzes the non-reducing end N-acetyl-D-hexosamine and/or sulfated N-acetyl-D-hexosamine of glycoconjugates, such as the oligosaccharide moieties from proteins and neutral glycolipids, or from certain mucopolysaccharides. The isozyme S is as active as the isozyme A on the anionic bis-sulfated glycans, the chondroitin-6-sulfate trisaccharide (C6S-3), and the dermatan sulfate pentasaccharide, and the sulfated glycosphingolipid SM2. The isozyme B does not hydrolyze each of these substrates, however hydrolyzes efficiently neutral oligosaccharide. Only the isozyme A is responsible for the degradation of GM2 gangliosides in the presence of GM2A.
