關(guān)于ELISA檢測中High/Low Control 已有1人參與
|

新手求問: 1.ELISA試劑盒中有High Control 和 Low Control ,這兩個指標的意義是什么? 酶標儀測出來這兩個試劑的OD值與試劑盒所給出的OD值如何比較? 2.試劑說明書中還有兩個指標,LLOQ, ULOQ: 根據(jù)解釋,意思是不是如果所測標本濃度在這兩個值的范圍之外,那么就要重新稀釋檢測? 所測標本濃度(test specimens )指的是不是稀釋過之后的濃度應(yīng)該在0.017~2.152 ng/ml 之間? LLOQ: The lower limit of quantitation (LLOQ) for the XXX Plus assay is 0.017 ng/mL, the lowest concentration on the standard curve that met internal criteria for accuracy and precision. ULOQ: The upper limit of quantitation (ULOQ) for the XXX Plus assay is 2.152 ng/mL, the highest concentration on the standard curve that met internal criteria for accuracy and precision. Diluted samples with a concentration above this limit should be retested at a higher dilution. When test specimens yield A450 values greater than the ULOQ or less than the LLOQ, obtain a more accurate XXX concentration by re-assaying the test specimens at a different dilution so the new A450 values will be within these limits. 萬分感謝~! |
