Exp2_R10_prot | R Documentation |
This dataset is the final outcome of a quantitative mass spectrometry-based proteomic analysis of two samples containing different concentrations of 48 human proteins (UPS1 standard from Sigma-Aldrich) within a constant yeast background (see Ramus et al. (2015) for details). It contains the abundance values of the different human and yeast peptides identified and quantified in these two conditions. The two conditions represent the measured abundances of peptides when respectively 10 fmol and 100 fmol of UPS1 human proteins were mixed with the yeast extract before mass spectrometry analyses. This results in a concentration ratio of 10. Three technical replicates were acquired for each condition.
The dataset is either available as a CSV file
(see inst/extdata/Exp2_R10_prot.txt), or as a MSnSet
structure
(Exp2_R10_prot.MSnset). In the latter case, the quantitative data are those of
the raw intensities.
data(Exp2_R10_prot)
An object of class MSnSet
related to proteins
quantification. It contains 6 samples divided into two conditions
(10 fmol and 100 fmol) and 948 proteins.
The data frame exprs(Exp2_R10_prot) contains six columns that are the quantitation of proteins for the six replicates.
The data frame fData(Exp2_R10_prot) contains the meta data about the proteins.
The data frame pData(Exp2_R10_prot) contains the experimental design and gives few informations about the samples.
