NEBNext® Single Cell/Low Input cDNA Synthesis & Amplification Module

Product Introduction

How low can you go?

NEBNext® is now available for single cell and ultra-low RNA inputs!

This unique cDNA synthesis and amplification workflow meets the demand for a highly sensitive, yet robust method that consistently ultimately enables generation of high quality sequencing data from single cell or ultra-low input RNA.

  • Generate the highest yields from single cells, or as little as 2 pg - 200 ng RNA
  • Experience unmatched detection of low abundance transcripts
  • Rely on consistent transcript detection for a wide range of input amounts and sample types
  • Observe uniform transcript coverage, regardless of input amount or sample type
  • Use with a variety of RNA inputs, including cultured or primary cells, or total RNA
  • Save time with a fast, streamlined workflow, minimal handling steps and hands-on time

Please note that this module contains only reagents for cDNA synthesis and amplification. The NEBNext Single Cell/Low Input RNA Library Prep Kit for Illumina® (NEB #E6420) includes reagents for DNA library construction.

Product Information

Description

The NEBNext® Single Cell/Low Input cDNA Synthesis & Amplification Module uses a template switching method to generate full length cDNAs directly from single cells or 2 pg – 200 ng RNA. This unique workflow enables generation of high quality sequencing data from a broad range of inputs, and superior transcript detection, while providing reliably consistent performance.

Features:

  • The highest yields from single cells, or 2 pg - 200 ng RNA
  • Input can be cultured or primary cells, or total RNA
  • Single-tube protocol from cell lysis to cDNA
  • Fast, streamlined, automation-friendly workflow, with minimal handling steps and hands-on time

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 cDNA Synthesis & Amplification Module or the SMART-Seq® v4 Ultra® Low Input RNA Kit for Sequencing (Clontech® # 634891) were used. cDNA libraries were amplified using the number of PCR cycles shown. Error bars indicate standard deviation for 8-21 replicates.
