I have used 20ng final concentration of template in my qPCR experiment, but not getting any difference between the Ct values of control and test group after drug treatment. Should i increase the concentration of template?
I have used 10ng/µl template concentration and succesfully detected differences in amplification between samples, so I don't think that increasing template concentration helps in this case. The simplest conclusion is that there is no difference between treatment group and control group.
