RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Summary

This summary is machine-generated.

We developed Supervised Integration using Domain Adaptation (SIDA), a new method to integrate single-cell RNA sequencing (scRNA-seq) data from different batches. SIDA improves cell type mapping accuracy by using existing cell type labels.
