Kingsoft Spreadsheets Free 2012 is an excellent alternative to Microsoft Excel. Not only does it allow you to work with the Excel documents that you already have, but it also offers some very similar functions while taking up a lot less space on your computer. Microsoft Excel 2013 might be the most robust application in the Office 2013 suite, and Excel has famously been one of the primary reasons for businesses to invest in the software set. Those that understand the full breadth of the app can use it to its full potential, and there is a lot of potential hiding deep in the program.

Despite the central role of quantitative PCR (qPCR) in thequantification of mRNA transcripts, most analyses of qPCR data arestill delegated to the software that comes with the qPCR apparatus.This is especially true for the handling of the fluorescence baseline.This article shows that baseline estimation errors are directlyreflected in the observed PCR efficiency values and are thus propagatedexponentially in the estimated starting concentrations as well as‘fold-difference' results. Because of the unknown origin and kineticsof the baseline fluorescence, the fluorescence values monitored in theinitial cycles of the PCR reaction cannot be used to estimate a usefulbaseline value. An algorithm that estimates the baseline byreconstructing the log-linear phase downward from the early plateauphase of the PCR reaction was developed and shown to lead to veryreproducible PCR efficiency values. PCR efficiency values weredetermined per sample by fitting a regression line to a subset of datapoints in the log-linear phase. The variability, as well as the bias,in qPCR results was significantly reduced when the mean of these PCRefficiencies per amplicon was used in the calculation of an estimate ofthe starting concentration per sample.

Dear LinRegPCR user,

We recently updatedLinRegPCR to implement the import and export of RDML files
Apps for macbook air.

RDML wasdeveloped as a standard for export, exchange, and storage ofquantitative PCR data and is supported by several large qPCR systemsuppliers as well as by data analysis software like qbase-plus.LinRegPCR now forms a link between your qPCR system and suchstatistical analysis software. LinRegPCR can handle RDML versions 1.0and 1.1, as well as RDML files in which floating point values arewritten with decimals points and decimal commas. LinRegPCR will writethe analysis results to an RDML file, version 1.1, with decimal pointstomaintain compatibilty with the current RDML specification.

The RDML input option is the mainaddition to LinRegPCR that was implemented in 2012. There were alsoseveral qPCR systems added to the list of input formats from Excelfiles. For other minor changes in the program, please have a look atthe recent updates listed on the LinRegPCR website (http://LinRegPCR.nl).

On our site you will also find a linkto a recent paper (Ruijter et al., Methods 2012), in which LinRegPCRand other publicly available PCR amplification curve analysis programswere compared. This paper is unique in the field of qPCR because allanalysis methods were applied by their original developers, and thus inthe currently recommended way. The paper was co-authored by thedevelopers of these curve analysis programs and members of the geNormteam, who performed the statistical analysis. The datasets used forthis comparison, and the analysis results, can be downloaded from http://qPCRDataMethods.hfrc.nl.

Addressingfluorogenic real-time qPCR inhibition using the novel custom Excel filesystem 'FocusField2-6GallupqPCRSet-upTool-001' to attain consistentlyhigh fidelity qPCR reactions.

The purpose of thismanuscript is to discuss fluorogenic real-time quantitative polymerasechain reaction (qPCR) inhibition and to introduce/define a novelMicrosoft Excel-based file system which provides a way to detect andavoid inhibition, and enables investigators to consistently designdynamically-sound, truly LOG-linear qPCR reactions very quickly. TheqPCR problems this invention solves are universal to all qPCRreactions, and it performs all necessary qPCR set-up calculations inabout 52 seconds (using a pentium 4 processor) for up to seven qPCRtargets and seventy-two samples at a time – calculations that commonlytake capable investigators days to finish. We have named this customExcel-based file system 'FocusField2- 6GallupqPCRSet-upTool-001'(FF2-6-001 qPCR set-up tool), and are in the process of transforming itinto professional qPCR set-up software to be made available in 2007.The current prototype is already fully functional.
