Product Information

Description

The NEBNext® Single Cell/Low Input RNA Library Prep Kit for Illumina® uses a template switching method to generate full length cDNAs directly from single cells or 2 pg – 200 ng RNA, followed by conversion to sequence-ready libraries using the Ultra™ II FS workflow. This unique workflow enables generation of the highest yields from a broad range of inputs, and superior transcript detection, while providing reliably consistent performance.

Please note that NEBNext Multiplex Oligos (Adaptors & Primers) are not included in the kit and are available separately. 

Features:

  • The highest yields of high-quality sequencing libraries from single cells, or 2 pg - 200 ng RNA
  • Input can be cultured or primary cells, or total RNA
  • Low abundance transcripts are easily detected
  • High quality libraries and sequence data are generated for a wide range input amounts and sample types
    • Full length transcript coverage
    • Consistent transcript detection
    • Superior transcript correlation
  • Fast, streamlined, automation-friendly workflow, with minimal handling steps and hands-on time
    • Single-tube protocol from cell lysis to cDNA
    • DNA fragmentation, end repair and dA-tailing reagents in a single enzyme mix, with a single protocol, regardless of GC content

Figure 1: NEBNext Single Cell/Low Input RNA Library Prep workflow


Figure 2: Higher library yields with the NEBNext Single Cell/Low Input RNA Library Prep Kit




Sequencing libraries were generated from HeLa, Jurkat and M1 single cells or 10 pg of Universal Human Reference (UHR) RNA (Agilent® #740000) with recommended amounts of ERCC RNA Spike-In Mix I (Thermo Fisher Scientific® #4456740). The NEBNext Single Cell/Low Input RNA Library Prep Kit, or the SMART-Seq v4 Ultra® Low Input RNA Kit for Sequencing (Clontech® #634891) plus the Nextera® XT DNA Library Prep Kit (Illumina® #FC-131-1096) were used. Error bars indicate standard deviation for 6-11 replicates. For the NEBNext workflow ~80% of the cDNA was used as input into sequencing library preparation, and libraries were amplified with 8 PCR cycles. For the SMART-Seq®v4/Nextera XT workflow, as recommended, 125 pg of cDNA was used as input in sequencing library preparation and 12 PCR cycles were used for amplification. Error bars indicate standard deviation for 6-11 replicates. 
Figure 3: Increased transcript detection with the NEBNext Single Cell/Low Input RNA Library Prep Kit




Sequencing libraries were generated from Jurkat single cells (6 replicates) using the NEBNext Single Cell/Low Input RNA Library Prep Kit, or the SMART-Seq v4 Ultra® Low Input RNA Kit for Sequencing (Clontech® # 634891) plus the Nextera XT DNA Library Prep Kit (Illumina® #FC-131-1096). Libraries were sequenced on an Illumina NextSeq® 500 using paired-end mode (2x76 bp). TPM = Transcripts per Kilobase Million. Each dot represents the number of transcripts identified at the given TPM range, and each box represents the median, first and third quartiles per replicate and method. Salmon 0.6 was used for read mapping and quantification of all GENCODE v25 transcripts. Panels show the number of transcripts detected within the following TPM ranges: 1-5, 5-10, 10-50 and >50 TPM. Increased identification of low abundance transcripts is observed with the NEBNext libraries.
Figure 4: The NEBNext Single Cell/Low Input RNA Library Prep Kit provides uniform coverage across the length of transcripts




Sequencing libraries were generated from HeLa, Jurkat and M1 single cells, or 10 pg of Universal Human Reference (UHR) RNA (Agilent® #740000) with recommended amounts of ERCC RNA Spike-In Mix I (Thermo Fisher Scientific #4456740). The NEBNext Single Cell/Low Input RNA Library Prep Kit, or the SMART-Seq v4 Ultra® Low Input RNA Kit for Sequencing (Clontech® # 634891) plus the Nextera XT DNA Library Prep Kit (Illumina® #FC-131-1096) were used. Libraries were sequenced on an Illumina NextSeq® 500 using paired-end mode (2x76 bp). Gene body coverage shown is an average of four replicates and was calculated using Picard tools. The global view of the 5´ to 3´ coverage of the RefSeq transcripts reveals both consistency across different sample types and uniformity across the transcript length in the NEBNext libraries.

Salmon 0.6 was used for read mapping and quantification of all GENCODE v25 transcripts. A higher number of transcripts were detected in the NEBNext libraries for all sample types.
