Why should you switch to silicon-carbide RNA isolation?

Conventional silica-based RNA purification kits suffer from size and GC bias

Conventional RNA purification kits isolate RNA using a simple silica-based matrix. This results in a biased RNA profile, with smaller RNAs (< 200 nt) missing. In addition, there is often a significant bias against GC-rich sequences. The image on the right shows a comparison of total RNA isolated using either a Norgen Total RNA Purification kit, or a kit from competitor Q. The loss of RNAs smaller than 200 nt in size with competitor Q's kit is clearly visible.

In contrast, Norgen's silicon-carbide based kits isolate uniform, highly pure RNA without size bias

  • Captures RNA of all sizes, including small RNAs & miRNAs
  • Maintains the original RNA size distribution profile
  • No bias against GC-rich sequences
  • No need for phenol
  • Highly efficient RNA purification, even from low input samples
  • Suitable for challenging downstream applications, including NGS

App. Note

 

Unbiased RNA isolation down to single cell level - for NGS applications

Silicon-carbide based RNA purification is especially powerful when it comes to limiting sample input. Using Norgen's Single Cell RNA Purifcation kit you can isolate RNA from a single cell up to 105 cells. Without size or GC bias, ready for challenging downstream applications such  as NGS.

  • Isolate highly pure RNA from a single cell
  • Fast processing using micro spin columns
  • Minimum elution volume: 8 ul
  • Uniform recovery, including small RNAs and miRNAs

 

Application note:
High-quality miRNA from a single mammalian cell
