This kit provides a rapid, single column method for the isolation and purification of total RNA (including miRNA) and proteins sequentially from a single sample of cultured animal cells, tissues, blood, bacteria, yeast, fungi or plants. The total RNA and proteins are both column purified in under 25 minutes using a single column.Purified RNA is of a high quality and yield, and is suitable for NGS, RT-qPCR and microarrays.This kit eliminates DNA efficiently using a gDNA removal column.Proteins are eluted in buffer and are ready for downstream applications such as Western Blots, Mass Spec and some ELISA applications. The proteins will not require precipitation, resuspending of pellets, or any further cleaning.This kit is ideal for researchers who are interested in studying the transcriptome and proteome of a single sample, such as for studies of microRNA profiling, gene expression including gene silencing experiments or mRNA knockdowns, studies involving biomarker discovery, and for characterization of cultured cell lines. Norgen’s RNA/Protein Purification Plus Kit is especially useful for researchers who are isolating macromolecules from precious, difficult to obtain or small samples such as biopsy materials or single foci from cell cultures, as it eliminates the need to fractionate the sample. Furthermore, analysis will be more reliable since the RNAand proteins are derived from the same sample, thereby eliminating inconsistent results. The purified macromolecules are of the highest purity and can be used in a number of different downstream applications.
