The RNeasy Maxi spin column contained in the RNeasy Maxi Kit.
RNeasy Kits provide the highest-quality RNA with minimum copurification of DNA. An additional buffer (composition provided) is required for isolation of cytoplasmic RNA from eukaryotic cells. Lyticase, zymolase, or glass beads (required for yeast samples) are not provided. Amounts of RNA isolated from samples can vary due to the developmental stage, species, and growth conditions of the sample source. Since the RNeasy procedure enriches for RNA species >200 nt, RNA yield does not include 5S rRNA, tRNAs, or other low-molecular-weight RNAs.
