SCRB-Seq

Single-Cell RNA Barcoding and Sequencing

SCRB-Seq is a cost-efficient, multiplexed, single-cell mRNA sequencing technique (Soumillon et al., 2014). SCRB-Seq isolates single cells into wells using FACS. After cell lysis, poly(A)+ mRNAs are annealed to a custom primer containing a poly(T) tract, UMI, well barcode, and biotin. Template-switching RT and PCR amplification reactions are carried out on the mRNA, generating barcoded, full-length cDNA. cDNA strands from all wells are pooled together to be purified. They are PCR-amplified and purified further. The cDNA libraries are prepared using the Nextera XT library preparation protocol, with modified i5 primers. The resultant cDNA fragments are size-selected for 300_800 bp and sequenced.

Advantages:

  • Cost-efficient, high-throughput, single-cell transcriptome profiling
  • Highly sensitive gene-detection results compared to popular scRNA-Seq techniques (Ziegenhain et al., 2016)

Disadvantages:


Reagents:

Illumina Library prep and Array Kit Selector
