Full transcriptome analysis of single cells with the SMART-Seq Stranded Kit
NOTE: For RNA sequencing resulting in stranded libraries from single cells, we recommend the reconfigured version of the kit below, SMART-Seq Total RNA Single Cell (ZapR Mammalian) (Cat. # 634360, 634361 & 634362).
The SMART-Seq Stranded Kit (Cat. # 634442, 634443 & 634444) will be phased out within a year. Contact your local sales representative for more information.
Get more out of your single-cell and ultra-low input RNA-seq with the SMART-Seq Stranded Kit. This kit uses a random-priming approach to capture the whole transcriptome, enabling analysis of nonpolyadenylated transcripts at the single-cell level. The kit contains reagents for generating stranded sequencing libraries, including cDNA synthesis and amplification, ZapR-mediated ribosomal RNA depletion, and Illumina-compatible library preparation.
If you prefer an oligo(dT) priming approach, we recommend SMART-Seq mRNA LP (with UMIs), SMART-Seq mRNA LP, or SMART-Seq mRNA HT LP.
Overview
- Simple workflow to generate stranded Illumina sequencing-ready libraries in 7 hours
- Appropriate for analysis of 1–1,000 intact mammalian cells or 10 pg–10 ng of low- or high-quality mammalian total RNA
- Reproducible, accurate detection of full-length coding and noncoding transcripts from single cells or total RNA
- Comparable sensitivity to our gold-standard SMART-Seq v4 Ultra Low Input RNA Kit for Sequencing.

Figure 2: High reproducibility across cell input amounts. A375 cells isolated by FACS were used to generate RNA-seq libraries with the SMART-Seq Stranded Kit. Input varied from 1 cell to 1,000 cells, with two replicates per input of 5–1,000 cells and 12 replicates for the single cells. For comparison, two aliquots of 1,000 cells were used for total RNA purification and then used for library preparation.
SMART-Seq Stranded Kit matches the sensitivity of SMART-Seq v4 technology
Figure 3. Comparison between SMART-Seq v4 and SMART-Seq Stranded kits. Single cells (K562) isolated by FACS were used to generate RNA-seq libraries with the SMART-Seq Stranded Kit (Stranded) and a SMART-Seq v4 Kit (SSv4; cDNA from this kit was further processed with a Nextera® XT DNA Library Preparation Kit). Panel A. The overlap in the total number of transcripts identified (FPKM >1) by each kit was analyzed and shown to be 83.8%. Panel B. The number of transcripts identified (FPKM >1) in individual cells was similar between the two kits, with a tighter range across cells processed with the SSv4 kit. Panel C. The reproducibility (Pearson correlation) of transcript expression levels across all cells from each kit was similar, although slightly higher and more consistent across cells processed with the Stranded kit.
