A convenient single-step liquid phase separation results in the simultaneous isolation of RNA, DNA, and protein.
This procedure is an improvement of the single-step method reported by Chomczynski and Sacchi for total RNA isolation.Keywords: AGE, Buffers, Digestions, Electrophoresis, Filtration, Gel electrophoresis, Nucleic acid hybridization, Precipitation, Purification, Scintillation, Separation, Sterilizations Sample Purification & Quality Assessment - PCR Technologies Guide The availability of simple methods for purification of DNA and RNA has greatly facilitated the analysis and characterization of the genome and gene expression.
