Positive用来确定你的检测方法能否检测到物质X （一面方法不对或机器损坏造成的无法检测的情况）Negative用来确定你检测方法是否有相应的无关信号对应X ,比如某种杂质跟X在一个时间出来，那么你就需要在最后计算样品量的时候减去这个量。两种解释,Definition of negative control :(Gene regulation) Transcripti...

The negative control is an experiment done with a sample/mock sample that should normally yield a negative result.It allows to check for contamination of the reagents or artifacts that would give false positive.Typically in a PCR that would mean running a PCR reaction with water as a template....
To promote the socio-economic development amid disease prevention and control in a coordinated manner and recover the normal production and life to the full extent, the PCR testing intervals are adjusted and optimized as follows: 一、自6月1日零时起,进入有明确防疫要求的公共场所和搭乘公共交通工具...
第二种 In an experiment the positive control is an experiment whose result is already known to be positive, it is used to check that nothing went wrong during the procedure. For a PCR detection test it would typically be the amplification of a sample known to yield the correct ...

Herein, the real-time RT-PCR assays confirmed that these three genes were up-regulated by more than 50 folds in the Δcrp mutant in relative to the WT strain (Fig. 2). Taken together, transcription of the sycO-ypkA-yopJ operon was under the negative control of CRP. Figure 2 CRP-...
