產品描述：人妊娠特異性β1糖蛋白(SP1/PSβ1-G)酶聯免疫試劑盒（CSB-E09133h）為競爭法ELISA試劑盒，定量檢測血清、血漿、組織勻漿樣本中的SP1/PSβ1-G含量。人妊娠特異性β1糖蛋白（SP1/PSβ1-G）是由胎盤合體滋養層細胞合成的特異性糖蛋白，具有免疫調節、抗炎和促血管生成作用。其結構/功能關系研究顯示，SP1可以與多種調節蛋白協同作用，通過保守的短線性基序參與蛋白質-蛋白質相互作用，對藥物設計和疾病診斷具有重要意義。試劑盒檢測范圍為1.0 μg/mL-400 μg/mL，適用于科研領域中對妊娠期母體血清或胎盤組織勻漿中SP1水平的動態監測，可應用于探究妊娠高血壓、胎兒生長受限等病理狀態下胎盤功能異常的分子機制，或用于評估體外模型中滋養層細胞分泌蛋白的功能研究。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%<15% Three samples of known concentration were tested twenty times on one plate to assess. Inter-assay Precision (Precision between assays): CV%<15% 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 SP1 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
