Total RNA purified with the RNeasy Mini 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. 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.|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. (E and O were kindly provided by P. Philippsen, University of Basel, Switzerland and U. Henning, Max Planck Institute of Biology, Tübingen, Germany, respectively.) B. subtilis was not probed. M: 0.24-9.5 kb RNA ladder. 7.5 kb band (indicated) in embryo, Huh7, and HeLa cell lanes is a nuclear precursor RNA.|RT-PCR of total RNA isolated with the RNeasy Mini Kit from the indicated numbers of HeLa cells. 10 µl (1/5) of eluate was digested with RNase-free DNase and reverse transcribed with oligo-dT primer. 2.5 µl (1/20) of the cDNA mix was used in 50 µl PCR. A 452 bp fragment of GAPDH was amplified. C-: negative control; C+: positive control; M: 100 bp ladder.|The RNeasy Mini spin column contained in the RNeasy Mini Kit.|
Performance

RNeasy Mini Kit可从至多30 mg动物或人类组织样本,或从100–1 x 107个动物或人类细胞样本或酵母中纯化总RNA(参见"RT-PCR of RNA from as few as 100 cells"和"High-quality RNA from a variety of samples")。

Principle

RNeasy Mini Kit可从少量的样本中高效纯化总RNA。RNeasy纯化技术整合了苯酚/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。纯化得到高品质的RNA,并且DNA残留水平达到最低。

Procedure
RNeasy Mini Kit可从10–1 x 107个动物或人类细胞中、0.5–30 mg动物或人类组织中或小于5 x 107个酵母细胞中方便的纯化总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 Mini spin column")。RNA结合到膜上(最多可结合100 µg),污染物被高效洗去。对于某些对少量DNA十分敏感的RNA应用,可在RNeasy操作过程中进行柱上DNA酶处理,去除DNA残留。之后可在30–100 µl的纯水洗脱液中得到高浓度的纯化RNA(参见"RNeasy Mini procedure")。还有各种特殊应用的实验方案可供选择。
Applications

使用RNeasy技术纯化得到的RNA的A260/280比为1.9–2.1(10 mM Tris­·Cl、pH 7.5的溶液中),适用于多种下游应用,包括:

  • Northern印迹、点印迹和狭缝印迹
  • 终点式RT-PCR
  • 定量real-time RT-PCR
  • 芯片分析
  • Poly A+ RNA筛选

Up to 1 x 109 bacteria are disrupted and homogenized by bead-milling in a guanidine-thiocyanate-containing lysis buffer. After addition of ethanol, the sample is loaded onto an RNeasy Mini spin column. Total RNA binds to the RNeasy silica-membrane, contaminants are efficiently washed away, and high-quality RNA is eluted in RNase-free water.

One milliliter of milk contains approximately 50,000-200,000 leukocytes (with an average of approximately 100,000 leukocytes). In a BVDV-infected animal up to 1-30% of the leukocytes may be infected with the virus. Each infected leukocyte typically contains 10-10,000 BVDV entities.
