Norgen Cytoplasmic and Nuclear RNA Purification Kit

SKU: 37400
Convenient purification of cytoplasmic and nuclear RNA from cultured cells and tissues.

Features and Benefits

Excellent separation and purification of cytoplasmic and nuclear RNA
Convenient and fast spin column format
High quality and yield of RNA
Isolate full diversity of RNA (including microRNA) without phenol
Purified RNA ready for any application (RT-PCR, qRT-PCR, RNA-Seq, arrays, etc.)
Cytoplasmic RNA is free of DNA and ready for direct use in RT-PCR/qRT-PCR
Based on spin column chromatography using Norgen’s proprietary resin separation matrix

Description

This kit provides a rapid method for isolating and purifying both cytoplasmic and nuclear RNA from cultured animal cells and small tissue samples. It isolates all RNA sizes, including small RNA species, without phenol.
Contains reagents for 50 cytoplasmic RNA preps or 25 cytoplasmic + 25 nuclear RNA preps. Ten samples can be processed in approximately 45 minutes. Also available in a 100 prep size.

Background

Fractionated RNA isolation allows targeted studies on mature cytoplasmic RNA or nuclear pre-processed RNA. The cytoplasmic fraction is free from genomic DNA contamination, enabling precise downstream analyses.

Supporting Data

Figure 1. Effective Separation of HeLa Cell Cytoplasmic & Nuclear RNA
Norgen’s kit effectively separates cytoplasmic and nuclear RNA from HeLa cells.

Panel A: High-quality RNA integrity shown on 1.5% formaldehyde-agarose gel.
Panel B: DNA gel confirms genomic DNA only in nuclear fraction.
Optional on-column DNase treatment removes nuclear DNA.

FAQs

Why do I have poor RNA recovery?

Possible causes include insufficient cell solubilization, column clogging, alternative elution buffer use, missing ethanol addition, or unwashed cell monolayer. Use recommended buffers and follow protocol precisely.

Why is the RNA degraded?

Potential causes: RNase contamination, slow procedure, improper RNA storage, thawed frozen samples, or improper tissue freezing. Maintain RNA integrity by working quickly and keeping samples cold.
