Single-cell RNA sequencing (scRNA-seq) offers new possibilities to address biological and medical ques-tions. However, systematic comparisons of the per-formance of diverse scRNA-seq protocols are lack-ing. We generated data from 583 mouse embryonic stem cells to evaluate six prominent scRNA-seq methods: CEL-seq2, Drop-seq, MARS-seq, SCRB Yanai and colleagues have developed CEL-Seq, an RNA-Seq method for assaying the transcriptome at the single-cell level.

All single cell RNA-seq protocols share a common initial step, where transcribed RNA from cells can be converted to cDNA. The next step is an amplification, using molecular biological methods such as polymerase chain reaction (PCR) or in vitro transcription (IVT). The subsequent steps, culminating in sequencing allow the expression level of gene products to be quantified. Eberwine et al. If you do have the DGE produced as a result of running through the drop-seq core computational protocol developed by James Nemesh of the McCarroll lab you should be good to go, as the DGE does not even have the XM (molecular barcodes) as part of the matrix. Each row is a gene name, and each column is the XC (cell barcode). So, if you have the cell barcode for your RNA-Seq reads, you should be. Single‐cell RNA‐seq has enabled gene expression to be studied at an unprecedented resolution. The promise of this technology is attracting a growing user base for single‐cell analysis methods.

In single-cell RNA sequencing experiments, doublets are generated from two cells. They typically arise due to errors in cell sorting or capture, especially in droplet-based protocols involving thousands of cells. Doublets are obviously undesirable when the aim is to characterize populations at the single-cell level. In particular, they can incorrectly suggest the existence of intermediate.

Ironically, most single-cell RNA sequencing protocols do actually synthesize full length cDNA but it is then fragmented for short-read sequencing. Since only the 3' end of the transcript is tagged with a cell barcode and an UMI during reverse transcription, internal and 5' fragments cannot be associated with a cell and their sequence information is lost. An obvious way to obtain full.

Single-cell RNA-seq (scRNA-seq) has become an established method for uncovering the intrinsic complexity within populations. Even within seemingly homogenous populations of isogenic yeast cells, there is a high degree of heterogeneity that originates from a compact and pervasively transcribed genome. Research with microorganisms such as yeast represents a major challenge for single-cell. SORT-seq is a partially robotized version of the CEL-seq2 protocol. Briefly, this is how it works: We receive your single cells, sorted into the wells of a prepared 384-well cell capture plate. Then, RNA molecules are barcoded with primers that contain a cell-specific barcode
In 2012, our lab published CEL-Seq, a method for single-cell RNA-Seq.
