microarray data analysis for detection and classification of viral infection

dna microarrays consist of collection of dna microscopic spots that in order to form an array attached to a solid surface such as glass, plastic or silicon chip. the pieces of fixed dna considered as a searcher. in this technology it is possible to test sample against thousands probes for specific genes. with this ability, arrays accelerate the biological investigations, gene finding, molecular...

Data Mining Methods for Microarray Data Analysis

The advent of gene expression microarray technology enables the simultaneous measurement of expression levels for thousands or tens of thousands of genes in a single experiment (Schena, et al., 1995). Analysis of gene expression microarray data presents unprecedented opportunities and challenges for data mining in areas such as gene clustering (Eisen, et al., 1998; Tamayo, et al., 1999), sample...

Reference : Microarray Data Analysis

If we are trying to identify genes that are not expressed identically in all populations and we have more than two populations, we have to try other methods than presented earlier. For example, consider the question: Is gene x expressed differently in three groups for us to conclude at the desired significance level gene x is expressed differently in the three populations. To do this, we use st...

Microarray Data Analysis

Micro-array Microarrays are microscopic array of single-stranded DNA molecules immobilized on a solid surface by biochemical synthesis also called as DNA chips, gene chips, biochips, DNA microarrays or simply the arrays. Basic idea behind microarray technology is to simultaneously measure the relative expression level of thousands of genes within a particular cell population or tissue. Microarr...
