How do I clean up RNA preparations containing miRNA?
RNA preparations containing miRNA can be cleaned up by modifying* the cleanup protocols listed in the handbooks of the RNeasy Mini Kit or the RNeasy MinElute Cleanup Kit .
* Modify the cleanup protocol at step 2, by increasing the volume of ethanol (96-100%) from 250 µl to 950 µl.

miRNeasy Serum/Plasma Kit
The miRNeasy Serum/Plasma Kit is designed for purification of cell-free total RNA — primarily miRNA and other small RNA — from small volumes of serum and plasma. RNA from serum and plasma typically consists of molecules <100 nucleotides. Purification can be automated on the QIAcube Connect.
The NEW miRNeasy Serum/Plasma Advanced Kit – get excellent results faster without phenol/chloroform using our QIAzol-free Advanced chemistry. Try it today.
miRNeasy Kits
miRNeasy Kits enable purification of total RNA from all types of animal tissues and cells, including difficult-to-lyse tissues and small tissue and cell samples. Alternatively, an miRNA-enriched fraction and a total RNA (>200 nt) fraction can be purified separately (for separate purification, an RNeasy MinElute Cleanup Kit is required when using the miRNeasy Micro or Mini Kit and an additional RNeasy 96 plate when using the miRNeasy 96 Kit). Purification of 1–12 samples can be automated on the QIAcube Connect. High-throughput processing in convenient 96-well format can be performed using centrifugation or vacuum procedures.

miRNeasy FFPE Kit
The miRNeasy FFPE Kit enables purification of total RNA that includes RNA from approximately 18 nucleotides upwards from formalin-fixed, paraffin-embedded (FFPE) tissue sections. The kit provides recovery of usable RNA fragments, including miRNA and other small RNAs, for applications such as quantitative, real-time RT-PCR. Procedures can be automated on the QIAcube Connect.
RNeasy Kits
RNeasy Kits are the gold standard for total RNA isolation. They provide fast purification of high-quality RNA from small to large amounts of cells, tissues, and yeast using silica membrane RNeasy spin columns or 96-well plates. Tissue samples can be conveniently stabilized using RNAprotect Tissue Reagent or Allprotect Tissue Reagent, and efficiently disrupted using a TissueRuptor II or TissueLyser II or LT system. The RNeasy 96 Kit enables high-throughput purification of total RNA from up to 96 cultured cell samples using silica membrane RNeasy 96 plates. A dedicated RNeasy QIAcube Kit enables automated purification of 1–12 samples on the QIAcube Connect.
RNeasy MinElute Cleanup Kit
The RNeasy MinElute Cleanup Kit enables cleanup and concentration of RNA from enzymatic reactions or other samples using specialized RNeasy MinElute spin columns based on silica-membrane technology. The kit can also be used to desalt RNA samples. Up to 45 µg RNA can be purified in a volume as low as 10 µl. Purification can be fully automated on the QIAcube Connect.
miRNeasy Tissue/Cells Advanced Kits
The miRNeasy Tissue/Cells Advanced Kits are the second generation of the well-established miRNeasy Kits. These improved versions combine a phenol-free advanced chemistry with gDNA Eliminator Columns or gDNA 96 Eliminator Plates for safe and convenient RNA isolation. They enable purification of total RNA, including small RNAs ≥18 nucleotides, from animal tissues and cells, including small samples. The kits use spin columns for low-throughput RNA purification. The miRNeasy Tissue/Cells Advanced Mini Kit can be automated on the QIAcube Connect.
