Microarray data analysis

Microarray data analysis involves examining thousands of genes simultaneously to understand their activity levels in a sample, such as a tissue or cell. The process begins with extracting genetic material, labeling it, and applying it to a microarray chip that contains many gene-specific spots. The chip's fluorescence signals reveal which genes are active and how strongly they are expressed. Data analysis then involves cleaning, normalizing, and interpreting these signals to identify patterns, such as genes involved in a disease or response to treatment. Overall, it helps researchers gain insights into gene functions and biological processes on a large scale.
