產品描述：小鼠γ分泌酶酶聯免疫試劑盒（CSB-E12142m）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APH1B含量。APH1B 是一種重要靶點。它在γ-分泌酶復合物中起關鍵作用。研究發現其與阿爾茨海默病等神經退行性疾病機制相關，可能參與調節淀粉樣蛋白生成。目前圍繞它探索新治療策略，深入了解其作用機制或為相關疾病防治帶來新思路。試劑盒檢測范圍為7.8 pg/mL-500 pg/mL，適用于腦組織樣本分析、疾病模型構建、神經退行機制探究等科研領域，可支持藥物開發中酶活性抑制劑的功效評估、轉基因動物模型驗證及病理狀態下γ分泌酶表達水平動態監測等實驗需求，為探索γ分泌酶在細胞信號傳導和疾病發生中的功能提供可靠工具。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。

精密度：
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 γ-Secretase in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay. Sample Serum(n=4) 1:1 Average % 96 Range % 90-102 1:2 Average % 102 Range % 97-107 1:4 Average % 89 Range % 87-93 1:8 Average % 94 Range % 90-98 -
回收率：
The recovery of mouse γ-Secretase spiked to levels throughout the range of the assay in various matrices was evaluated. Samples were diluted prior to assay as directed in the Sample Preparation section. Sample Type Average % Recovery Range Serum (n=5) 103 99-106 EDTA plasma (n=4) 95 89-102 -

靶點詳情

功能：Probable subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral proteins such as Notch receptors and APP (amyloid-beta precursor protein). It probably represents a stabilizing cofactor for the presenilin homodimer that promotes the formation of a stable complex. Probably present in a minority of gamma-secretase complexes compared to APH1A.
