Principle
The Kit is for the purification of total RNA from 2.5 ml human whole blood collected in a PAXgene Blood RNA Tube. Purification begins with a centrifugation step to pellet nucleic acids in the PAXgene Blood RNA Tube. The pellet is washed and resuspended, and incubated in optimized buffers together with proteinase K. DNA wash The lysate is passed through a DNA Mini column. Ethanolis added to adjust binding conditions, and the lysate is applied to a column.RNA is selectively bound to the silica membrane as contaminants pass through. Remaining contaminants are removed in several efficient wash steps. Between the first and second wash steps, the membrane is treated with DNase I to remove trace amounts of bound DNA. After the wash steps, RNA is eluted in elution buffer and heat-denatured.
Advantages
- High quality – high purity total RNA can be directly used in various sensitive downstream applications
- Fast – isolation of several samples can be completed in 40 minutes by using column purification method
- Safety – no phenol chloroform extraction required
- Sensitive – direct lysis of blood, plasma and other samples without separation of leukocytes

Storage and Stability
Proteinase K should be stored at 2–8°C upon arrival. DNase I should be stored at -20°C. However, short-term storage (DNase I up to 1 weeks, Proteinase K up to 8 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under these conditions.
