Formaldehyde-Free RNA Gel Kit

Formaldehyde-Free RNA Gel Kit
Code: N726-KIT

Formaldehyde-Free denaturing agarose electrophoresis of RNA

  • Hood-free pouring and running - completely formaldehyde-free
  • Eliminate long incubations and buffer recirculation - glyoxal-free formulation
  • Sample preparation - denature and stain samples in a single step
  • Instant band visualization - low background and brilliant green bands without the need for ethidium bromide
  • Compatible with down-stream applications including Northern Blots

Resolution of Total RNA on a Formaldehyde-Free RNA Gel

Formaldehyde-Free RNA Gel Kit
Figure 1. Comparison of Formaldehyde-Free RNA dye to ethidium bromide staining. Total RNA was extracted from K562 cells with Ribozol® RNA Extraction Reagent (N580). Samples were denatured in Formaldehyde-Free RNA Loading Buffer containing either ethidium bromide or Formaldehyde-Free RNA dye and incubated for 10 minutes at 65°C. The samples were applied to a 2% Formaldehyde-Free RNA Agarose Gel (Agarose I™, Code:0710) and resolved for 1.5 hours at 5.1 V/cm. Image capture was performed with a Syngene GBox-HR Gel Doc System with a SYBR® Green filter.

Kit Contents

  • Formaldehyde-Free RNA Gel Solution, 10X
  • Formaldehyde-Free RNA Running Buffer, 10X
  • Formaldehyde-Free`` RNA Loading Buffer, 2X - bromophenol blue and xylene cyanol included as tracking dyes.

Norther Blot of Formaldehyde Free RNA Gel

Northern Blot Analysis of PGK1 mRNA

Figure 2. Northern blot analysis of PGK1 mRNA resolved on Formaldehyde-Free RNA Gel. Data provided by Jeff Coller, Ph.D., Center for RNA Molecular Biology, Case Western Reserve University, Cleveland, Ohio. Gel A: 20 μg of total yeast RNA was applied per lane to an agarose Formaldehyde-Free RNA Gel and resolved at 8V/cm. Bands were visualized on a UV transilluminator Gel B: Bands were transferred to Hybond N membrane and probed overnight with a radiolabelled oligonucleotide to PGK1 mRNA. Gel C: Membranes were stripped and reprobed over night with an oligonucleotide to SCR1 RNA loading control.
