qPCR standard curve planning
A qPCR standard curve uses a dilution series to connect concentration with amplification signal.
This tool builds a concentration table and a practical dilution-step summary.

}FAQ
qPCR Dilution / Standard Curve Tool questions
What dilution factor should I use?↑
Ten-fold dilutions are common, but five-fold or other series may be appropriate depending on assay range.
What does replicate number do?↑
It helps estimate how many wells or reactions are needed for each standard point.
Does this calculate Ct values?↑
No. It prepares dilution concentrations; Ct values come from the qPCR run.
Should standards cover the unknown sample range?↑
Yes. The standard curve should span the expected concentration range of unknown samples.
