229 Microarray Data Analysis is called expression ratio. It is denoted here as Tk and defi ned as: and defi ned as: k Tk =. Rk. G For each gene k on the array, where on the array, where Rk represents the spot intensity metric for the test sample and Gk represents the spot intensity metric for …
Microarray Data Analysis. Clustering is one of the unsupervised approaches to classify data into groups of genes or samples with similar patterns that are characteristic to the group. Classification is supervised learning and also known as class prediction or discriminant analysis. Generally, classification is a process of learning-from-examples.

Protein (i) and Carbohydrate (ii) microarrays are two examples of extension of using these tools for high throughput analysis of dierent types of molecules. Tissue microarrays (iii) are a dierent type of extension where the substract is not dierent arianvts of a single type of molecule but of a type of tissues.
A microarray is a collection of small DNA spots attached to a solid surface. In microarray experiments, the signal collected from each spot is used to estimate the expression level of a gene. A microarray contains thousands of DNA spots, covering almost every gene in a genome. o The first high-throughput technology for gene expression analysis.

Microarray Analysis. Microarray analysis of gene expression has developed into a powerful tool for the characterization of many pathophysiologic processes. The basic idea is that RNA isolated from tissue is hybridized to probes for specific genes that are fixed in a grid in small microscopic spots.
