The Monarch Total RNA Miniprep Kit is a comprehensive solution for sample preservation, cell lysis, gDNA removal, and purification of total RNA from a wide variety of biological samples, including cultured cells, blood, and mammalian tissues. Additionally, tough-to-lyse samples, such as bacteria, yeast, and plant, can be processed with additional steps that enhance lysis. Total RNA, including viral RNA, can also be extracted from clinically relevant samples like saliva and swabs. Cleanup of enzymatic reactions or purification of RNA from TRIzol-extracted samples is also possible using this kit. Purified RNA is highly pure, has minimal residual gDNA and ranges in size from full-length rRNAs down to intact miRNAs. Additionally, differential binding conditions allow selective capture or exclusion of the sub-200 nucleotide RNA pool that includes miRNA, 5S rRNA, and tRNA. Purified RNA is suitable for downstream applications, such as RT-qPCR, RNA-seq, Northern blot analysis, etc.
