For 96-well purification of microRNA and total RNA from tissues and cells
  • Effective purification of miRNA and total RNA
  • Efficient enrichment of miRNA and RNAs <200 nucleotides
  • High-purity RNA suitable for all downstream applications
  • Protocols for copurification or isolation of separate fractions

The miRNeasy 96 Kit enables purification of total RNA, which includes RNA from approximately 18 nucleotides (nt) upwards from all types of animal tissues and cells, including difficult-to-lyse tissues. Alternatively, an miRNA-enriched fraction and a total RNA (>200 nt) fraction can be purified separately (for separate purification, an additional RNeasy 96 plate is required; for economical purchase of an additional RNeasy 96 plate and wash buffers, we recommend ordering an RNeasy 96 Kit).  Manual purification is carried out using the Centrifuge 4K15C or the Centrifuge 4-16K and, optionally, the QIAvac 96 vacuum manifold.

Total RNA was purified from [A] 102–107 Jurkat cells using the miRNeasy 96 Kit or [B] a dilution series of rat lung tissue homogenate from 20 mg to 200 ng using the miRNeasy Mini Kit. miRNA-enriched fractions (<200 nt) were also isolated from the same samples. Purified RNA was used as a template in quantitative, real-time RT-PCR assays for the miRNA miR-16.|Total RNA including miRNA was purified from 25 mg of a range of RNAlater stabilized rat tissues using the miRNeasy 96 Kit. Purified RNA was used as a template in quantitative, real-time RT-PCR assays for the miRNA miR-16 and for the larger mRNA of the PGK1 gene. Results showed successful detection of both PGK1 mRNA (large RNA) and miR-16 (small RNA) from the same eluates.|Total RNA including miRNA was purified from a range of amounts of Jurkat cells using the miRNeasy Mini Kit or TRIzol Reagent. Purified RNA was used as a template in quantitative, real-time RT-PCR assays for the miRNA miR-16. Results showed that CT values were lower after purification using the miRNeasy Kit, indicating that higher amounts of miRNA were purified than using TRIzol. miRNA was effectively purified from as little as 1 x 102 cells using the miRNeasy Kit. In contrast, no miRNA was detected after 40 PCR cycles from 1 x 102 cells when TRIzol was used for purification.|miRNA-enriched fractions were purified from 3 x 106 HeLa cells using either the miRNeasy Mini Kit or a kit from Supplier AIV. Equal RNA amounts from miRNA-enriched fractions were run on a 1.5% gel. For comparison, 20mer and 21mer synthetic RNAs were also run on the gel. The miRNA-enriched fraction prepared using the miRNeasy Kit showed a smear of RNAs of different sizes down to approximately 18 nt. In contrast, in the miRNA-enriched fraction prepared using the kit from Supplier AIV, primarily tRNA and 5S rRNA were visible.|Total RNA including miRNA was purified from 1 x 106 Jurkat cells using the miRNeasy Mini Kit or TRIzol Reagent. The absorbance spectra showed the OD maximum for RNA purified using the miRNeasy Kit was at 260 nm. In contrast, the OD maximum was greater than 260 nm when TRIzol was used for purification, indicating phenol carryover. In addition, the OD230 measurement was higher in the TRIzol-prepared RNA, indicating salt carryover from the TRIzol Reagent.|The miRNeasy Mini Kit enables purification of total RNA which includes RNA from 18 nucleotides (nt) upwards. Alternatively, an miRNA-enriched fraction and a total RNA (>200 nt) fraction can be can be purified separately. A separate miRNA-enriched fraction may be required to reduce background in particularly sensitive downstream applications.|
Performance

Purification of total RNA including miRNA allows direct comparison of miRNA expression levels with those of housekeeping reference genes or any other mRNA of interest. miRNeasy Kits enable efficient enrichment of RNA down to approximately 18 nt in size. The presence of very small RNAs is clearly visible after purification using an miRNeasy Mini Kit, in contrast to samples prepared using an alternative kit (see figure "Effective enrichment of small RNA"). miRNeasy Kits efficiently purify RNA from both tissues and cells, even when low amounts of starting material are used (see figure "Effective purification from a range of starting amounts"). 

RNA can be purified with the kit from a variety of samples, including difficult-to-lyse tissues (see figure "Efficient copurification from a wide range of tissues"). miRNeasy procedures eliminate the possibility of contamination with salts or phenol which could interfere with later analyses (see figure "Highly pure RNA without phenol carryover"). In addition to higher purity, miRNeasy Kits offer superior yields to alternative methods of miRNA purification, such as using TRIzol Reagent (see figure "miRNeasy Kit outperforms TRIzol"). RNA prepared using miRNeasy Kits is highly pure and ready for use in sensitive downstream applications.

Principle

The miRNeasy 96 Kit combines phenol/guanidine-based sample lysis and silica membrane-based RNA purification with the speed of vacuum and/or spin processing. QIAzol Lysis Reagent, included in the kit, is a monophasic solution of phenol and guanidine thiocyanate, designed to facilitate lysis of tissues, to inhibit RNases, and also to remove most of the cellular DNA and proteins from the lysate by organic extraction.

Procedure

The miRNeasy 96 Kit enables purification of total RNA which includes RNA from 18 nucleotides (nt) upwards. Alternatively, an miRNA-enriched fraction and a total RNA (>200 nt) fraction can be can be purified separately (see flowchart "miRNeasy procedures"). The separate miRNA-enriched fraction may be required to reduce background in particularly sensitive downstream applications. For this specialized protocol, enabling enrichment of miRNAs and other small RNAs (<200 nt), 2 RNeasy 96 plates are required for every 96 samples.
