All-in-one DNA/RNA/Protein Mini-Preps Kit (cells, tissues, plants): All-in-one DNA/RNA Mini-Preps Kit is designed for simultaneous extraction of total RNA, and genomic DNA from a single biological sample. DNA and RNA are isolated without cleaving the sample prior to extraction. DNA and RNA can be isolated from cultured eukaryotic cells and from animal and plant tissues. This kit, which uses a harmless buffer system, does not require phenol or chloroform extractions and provides a column to separate pure genomic DNA from total RNA. The purified DNA is suitable for downstream applications such as restriction endonuclease digests, PCR, etc. Isolated RNA can be used for mRNA isolations, probe generation, RT-PCR, northern blot analysis, primer extension. RNA protection assay and in vitro transalation. The procedure is simple and fast. Genomic DNA and RNA can be isolated in less than 40 minutes.
