Assessment of DNA Contamination in RNA Samples Based on Ribosomal DNA Seyyed Hamidreza Hashemipetroudi1, Ghorbanali Nematzadeh1, Gholamreza Ahmadian2, Ahad Yamchi3, Markus Kuhlmann4 1Genetic and Agricultural Biotechnology Institute of Tabarestan (GABIT), Sari Agricultural Sciences and Natural Resources University (SANRU), 2Department of Industrial and Environmental Biotechnology, National Institute of Genetics Engineering and Biotechnology (NIGEB), 3Department of Plant Breeding and Biotechnology, Gorgan University of Agricultural Sciences & Natural Resources, 4RG Abiotic Stress Genomics/ RG Heterosis, Department Molecular Genetics, Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) Here, we present a protocol for tracing genomic DNA (gDNA) contamination in RNA samples. The presented method utilizes primers specific for the internal transcribed spacer region (ITS) of ribosomal DNA (rDNA) genes. The method is suited for reliable and sensitive detection of DNA contamination in most eukaryotes and prokaryotes.
A Fast Air-dry Dropping Chromosome Preparation Method Suitable for FISH in Plants Lala Aliyeva-Schnorr1, Lu Ma1,2, Andreas Houben1 1Leibniz Institute of Plant Genetics and Crop Plant Research (IPK), 2School of Biological and Chemical Sciences, Queen Mary University of London A protocol is described for the preparation of high-quality mitotic plant chromosome spreads by a fast air-dry dropping method suitable for the FISH detection of single and high copy DNA probes.
