The RNeasy Midi Kit is intended for molecular biology applications. This product is not intended for the diagnosis, prevention, or treatment of a disease.

Total RNA purified with the RNeasy Midi Kit is of high quality and is suitable for many downstream applications. Protocols are also included for cleanup of partially purified RNA, in vitro transcripts, and RNA from enzymatic reactions. An additional buffer is required (composition provided) 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.

Principle
RNeasy Midi Kit可从中量起始样本中高效纯化RNA。RNeasy技术整合了苯酚/异硫氰酸胍裂解的严谨性和硅胶膜纯化的速度和纯度,简化了总RNA纯化技术。RNeasy Kits可纯化得到极高品质的RNA,DNA污染达到最低。
Procedure
RNeasy Midi Kit可从5 x 10 6–1 x 10 8个动物或人类细胞、20–250 mg动物或人类组织或2 x 10 7–5 x 10 8个酵母细胞中简单的纯化总RNA。先对样本进行破碎和匀浆。在裂解物中加入乙醇以提供合适的结合条件。然后将裂解物上样至RNeasy硅胶膜(参见" RNeasy Midi spin column")。 RNA(至多1 mg)结合到膜上,污染物被高效洗去。对于某些对少量DNA十分敏感的RNA应用,可进行方便的柱上DNase处理,去除残留的DNA。之后可用300–500 µl水洗脱得到高浓度的纯化RNA(参见" RNeasy Midi procedure" )。还有一系列特殊应用的实验方案可选。
Applications

High-quality RNA from a variety of samples.
Formaldehyde agarose gel and northern blot of total RNA purified with the RNeasy Maxi Kit. Total RNA (10 µg) isolated from each source was loaded per lane. All tissues were from mouse. Yeast: Saccharomyces cerevisiae; E. coli strain: HB101. 32P-labeled probes recognized (G) GAPDH; (E) translation elongation factor EF-1α; and (O) outer membrane protein A sequences.
