Transcriptomics is the study of the set of transcripts produced by the genome of a particular cell, tissue, or organism. Transcriptomics data provides an insight into gene expression patterns and how they may change based on the environment, nutritional status, and other factors.

The data collected from studies can be used to better understand cell biology, investigate disease mechanisms, and develop new therapeutic strategies. There are several types of transcriptomic data that are collected and used in research.

These types include

 RNA Sequencing (RNA-Seq): This type of is generated through the sequencing of RNA molecules. It allows for an accurate measurement of gene expression levels, alternative splicing, and other transcriptional features. RNA-Seq is also used to characterize gene expression changes in response to external stimuli and to investigate gene expression patterns in different tissues and cell types.

 Gene Expression Profiling (GEP): This type of transcriptomic data is used to measure the expression levels of thousands of genes simultaneously. It can be used to identify genes that are differentially expressed in different states or conditions, or to compare expression patterns between different samples.

 Microarray Analysis: This type of transcriptomic data is generated by hybridizing labeled cDNA or cRNA with a DNA, RNA, or protein microarray. It is used to investigate gene expression patterns on a genome-wide scale and to identify genes that are differentially expressed in different states or conditions. 

Digital Gene Expression (DGE): This type of transcriptomic data is generated by sequencing short cDNA fragments. It is used to accurately measure gene expression levels in tissues and cell types, and to identify differentially expressed genes in response to external stimuli. 

Massively Parallel Signature Sequencing (MPSS): This type of transcriptomic data is generated by sequencing the ends of cDNA molecules. It is used to measure gene expression levels in a high-throughput manner and to identify differentially expressed genes. Overall, provides a wealth of information about gene expression patterns and how they may change in different conditions. This data can be used to better understand cell biology, investigate disease mechanisms, and develop new therapeutic strategies.
