NormFinder software
Determine the optimal normalization gene
NormFinder is an algorithm for identifying the optimal normalization gene among a set of candidates.
It ranks the set of candidate normalization genes according to their expression stability in a given sample set and given experimental design.
NormFinder can analyze expression data obtained through any quantitative method e.g. real time RT-PCR and microarray based expression analysis.
"NormFinder.xla" adds the NormFinder functionality directly to Excel. A version for R ( updated June 2014) is also available.
License
The NormFinder software is free for both academical and commercial use. Modification or redistribution of the software is not allowed.
When publishing scientific results, where NormFinder software has been used, please cite the original article.
Several alternative normalization software is available, find more information here.
Compatibility
The add-on is compatible with 32 bit Office versions 2003, 2010, 2016. Running the add-on in MS Office 64-bit versions or Mac Offce 2019 will cause the error 438.
