Product Details

Consistent highly pure RNA.
RNA was purified from 2-3 replicate tissue samples from each of 4 types of rat tissue using the EZ1 RNA Tissue Mini procedure. Purified total RNA was examined by scanning spectrophotometry. [A] Kidney, 10 mg; [B] liver, 10 mg; [C] pancreas, 5 mg; [D] spleen, 5 mg.
Efficient purification and reproducible yields.
Using the EZ1 RNA Tissue Mini procedure, total RNA was purified from 10 mg samples of rat kidney and liver and from 5 mg samples of rat pancreas, spleen, and lung. RNA was purified from 3 replicate samples of each tissue type. Yields of total RNA were determined by absorbance (A260) with correction for background (A320). CV kidney = 15%; CV liver = 1%; CV pancreas = 8%; CV spleen = 10%; CV lung = 22%.

The yields and high quality of total RNA purified using the EZ1 RNA Tissue Mini Kit are consistent and reproducible (see figures "Efficient purification and reproducible yields" and "Consistent highly pure RNA").


Automated purification with the EZ1 RNA Tissue Mini Kit requires use of the EZ1 Advanced XL and the EZ1 Advanced XL RNA Card, or the EZ1 Advanced and the EZ1 Advanced RNA Card, or the BioRobot EZ1 and the EZ1 RNA Card. EZ1 cards are preprogrammed with protocols that guide the user through worktable setup and provide the instrument with commands for the purification procedure.

Using silica-coated magnetic-particle technology, the easy-to-use instrument allows purification of 1-14 samples (EZ1 Advanced XL) or 1-6 samples (EZ1 Advanced and BioRobot EZ1) in a single run. Presealed reagent cartridges and the automatic sensor-controlled lock of the instrument door reduce the chances of environmental contamination or degradation due to RNases. The automated procedure provides high repeatability and linear yields over a range of starting amounts. The flexibility to purify high-quality total RNA from a wide range of tissue types ensures that samples can be purified for a range of gene expression analysis applications. RNA yield using the EZ1 RNA Tissue Mini Kit is dependent upon many variables, including sample weight, tissue type and developmental state.


Tissues are first lysed and homogenized in Buffer RLT. RNA is then purified in one step on the instrument following the automated EZ1 RNA procedure. For certain RNA applications that are sensitive to very small amounts of DNA, an integrated DNase digestion step removes genomic DNA contamination. Total RNA is eluted in 200 µl, 100 µl, or 50 µl, ready to use in all downstream applications.


The high-quality RNA obtained using the EZ1 RNA Tissue Mini Kit is suited for use in many applications, such as:

  • Gene expression analysis using real-time RT-PCR technologies
  • Gene expression analysis using microarray technologies
  • Oncology and pathology research
