大鼠前列(lie)腺(xian)素E2(PGE2)ELISA試(shi)劑盒說明書
本試劑盒僅供研究使用。
藥品名稱(cheng):
通用名:大鼠前列腺素E2(PGE2)酶聯免疫分析試劑盒
使(shi)用目的:
本試劑盒用于測定大鼠血清,血漿及相關組織樣本中前(qian)列腺素E2(PGE2)含量。
實(shi)驗原理
本試劑盒應用雙抗體夾心法測定標本中大鼠前列腺素E2(PGE2)水平。用純化的大鼠前列腺素E2(PGE2)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前列腺素E2(PGE2),再與HRP標記的羊抗鼠抗體結合,形成抗體-抗原-酶標抗體復合物,經過*洗滌后加底物TMB顯色。TMB在HRP酶的催化下轉化成藍色,并在酸的作用下轉化成zui終的黃色。顏色的深淺和樣品中的前列腺素E2呈正相關。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大鼠前列腺素(su)E2(PGE2)濃度。
