    Article Snippet: These five kits are TRIzol Reagent (Life Technologies), RNeasy Plant mini kit (Qiagen), Spectrum™ Plant Total RNA kit (Sigma), AccuPrep viral RNA extraction kit (Bioneer) and Plant/fungi total RNA kit (Norgen BioTek).

    Techniques: Isolation, Nucleic Acid Electrophoresis, RNA Extraction, Electrophoresis, Chromatin Immunoprecipitation
