In recent years single cell RNA-seq (scRNA-seq) has become widely used for transcriptome analysis in many areas of biology. Single Cell Workshop. However, the analysis of the large volumes of data generated from these experiments requires specialized statistical and computational methods. The next step is to extract the CB and … In contrast to bulk RNA-seq, scRNA-seq provides quantitative measurements of the expression of every gene in a single cell. As a first step, a single-cell suspension is generated in a process called single-cell dissociation in which the tissue is digested. Single-Cell Analysis by Use of ICP-MS. Theiner, S. et al. Depending on the library preparation method used, the RNA sequences (also referred to as reads or tags), will be derived either from the 3’ ends (or 5’ ends) of the transcripts (10X Genomics, CEL-seq2, Drop-seq, inDrops) or from full-length transcripts (Smart-seq). Basic analysis of spatial data: → tutorial: spatial/basic-analysis. Seurat is an R package designed for QC, analysis, and exploration of single-cell RNA-seq data.
