- 人α葡萄糖苷酶（α-glucosidase）試劑盒使用方法
- 檢測范圍：96T7U/L-200U/L使用目的：本試劑盒用于測定人血清、血漿及相關(guān)液體樣本中α葡萄糖苷酶（α-glucosidase）含量。實驗原理本試劑盒應(yīng)用雙抗體夾心法測定標本中人α葡萄糖苷酶（α-glucosidase）水平。用純化的人α葡萄糖苷酶（α-glucosidase）抗體包被微孔板，制成固相抗體，往包被單抗的微孔中依次加入α葡萄糖苷酶（α-glucosidase），再與HRP標記的α葡萄糖苷酶（α-glucosidase）抗體結(jié)合，形成抗體-抗原-酶標抗體復合物，經(jīng)過徹底洗滌后加底物TMB顯色。TMB在HRP酶的催化下轉(zhuǎn)化成藍色，并在酸的作用下轉(zhuǎn)化成Z終的黃色。顏色的深淺和樣品中的α葡萄糖苷酶（α-glucosidase）呈正相關(guān)。用酶標儀在450nm波長下測定吸光度（OD值），通過標準曲線計算樣品中人α葡萄糖苷酶（α-glucosidase）濃度。[詳細]
