Method for evaluation of purity of biological sample used in the microarray experiment, basing on the obtained profile of expression of genes

摘要

the invention relates to the method of evaluation of biological samples used in the experiment mikromacierzowym based on the profile of gene expression.according to which, after hybridization of biological material to mikromacierzy and readings from mikromacierzowego scanner, the definition of biomarkers tissues forming pollution and control group with expression of all genes on mikromacierzy is id entyfikacji pollution tissue for each sample.an expression profile of genes and on the basis of statistical test comparing the expression profile of tissue biomarkers in a sample from the expression of other genes on mikromacierzy estimated purity of each sample and its suitability for use in further stages procesowania based on accepted limit p-value and the p - value for each sample and foreach pollutant.
