Microarray analysis is a high-throughput method that has been widely used to profile gene expression. DNA microarrays are assays for quantifying amounts of mRNA transcripts present in a sample from which RNA is extracted and the mRNA is isolated. The mRNA transcripts quantified and the number of mRNA molecules derived from transcription of a given gene is an approximate estimate of the level of expression of that gene. This platform ,designed by VironIT, aims at performing the complete analysis of gene expression microarray data.
