RNA (and DNA) from PAGE gels


  • Efficient: Recovery of ss- or ds- RNA (and DNA) fragments (17-200 nt) from up to 20% (w/v) polyacrylamide gels.
  • Concentrated: Up to 10 µg sample in ≥ 6 µl elution.
  • Compatible with up to 25% (w/v) polyacrylamide.


The ZR small-RNA PAGE Recovery Kit provides an easy and efficient method for the extraction of high quality small RNAs from polyacrylamide gels (native and/or denatured). The ZR small-RNA™ PAGE Recovery Kit is a refinement of the "crush and soak" method that incorporates a unique buffer system together with Zymo-Spin column technologies for improved recovery and added convenience. The recovered RNA can be concentrated into volumes as small as 6 µl, making it ideal for many downstream enzymatic reactions and manipulations.

Uncleaved RNA transcripts were extracted from denaturing (8.3M ura) 10% polyacrylamide gel using the ZR small-RNA PAGE Recovery kit. This facilitates the generation of ribozyme-based control devices for gene regulatory activities.

The ZR Small-RNA PAGE Recovery kit was used to gel purify short RNAs (50-250 bp) from isolated total RNA on a 15% TBE Urea gel for downstream quantitative PCR.

In vitro transcribed short hairpin RNA constructs were recovered from 20% denaturing polyacrylamide gels using the ZR small-RNA PAGE Recovery kit. This was used to show that influenza A virus panhandle structure could bind to retinoic acid-inducible gene I (RIG-I) and affect type I interferon production.
