For example many assume that CB2 receptors are not expressed in brain, this is in fact inaccurate; although expression of this receptor can be induced in immune cells, they are resident in brain microglia or simply infiltrating immune cells [ 9].
This uniform variance assumption is often inaccurate for expression compendia, because multiple measurement technologies applied in multiple labs will almost certainly have different errors associated with them.
As a result, clinical conclusions are based on potentially inaccurate protein expression levels, because these levels are derived from quantifying peptides that may not be representative of all of the diverse forms of protein molecules present.
As reads from a foreign sample would lead to inaccurate gene expression estimates, we removed these samples from downstream analysis, resulting in a final data set of 57 samples, comprising 21 controls and 36 cases.
And since when is a clumsy, propagandish, inaccurate film an expression of "American values"?
In addition, sequencing errors in the current Arabidopsis genome assembly may have caused incorrect assignment of some MPSS tags and thus inaccurate determination of expression.
§ The microarray result of the ctfB gene at S phase was inaccurate because its expression level exceeded the detection upper limit.
