Intended Use

The PAXgene Tissue DNA Kit is intended for the purification of DNA from PAXgene Tissue fixed (PF) and PAXgene Tissue fixed, paraffin-embedded (PFPE) tissue samples. The kit is intended to be used as part of the PAXgene Tissue System, which additionally includes the PAXgene Tissue Container or PAXgene Tissue FIX Container and the PAXgene Tissue STABILIZER Concentrate for the collection, fixation, stabilization, and storage of tissue samples.

For research use only. Not for use in diagnostic procedures. No claim or representation is intended to provide information for the diagnosis, prevention, or treatment of a disease. The performance characteristics of this product have not been fully established.

Performance

Total DNA purified using the PAXgene Tissue DNA Kit is highly pure. DNA has A260/A280 ratios of 1.7–1.9, and absorbance scans show a symmetrical peak at 260 nm, confirming high purity of genomic DNA. Contamination is minimal and purified DNA is ready to use in downstream applications with no detectable inhibition of PCR (see High-quality DNA from PFPE tissue with preserved morphology and DNA without chemical modifications can be used for demanding downstream applications).
 

Principle

The PAXgene Tissue DNA Kit enables purification of DNA from tissues fixed and stabilized using the PAXgene Fixation and Stabilization products, which preserve tissue morphology and biomolecule integrity by avoiding destructive cross-linking and degradation found in formalin-fixed tissues. The purified DNA has no inhibitory chemical modifications and thus, can be used in sensitive downstream applications.

 

Procedure

PAxgene Tissue fixed (PF) or PAXgene Tissue fixed, paraffin-embedded (PFPE) tissue samples are lysed in Buffer TD1 with proteinase K. Conditions are adjusted for optimal binding of DNA to the silica membrane and the lysate is loaded on the PAXgene DNA spin column. DNA binds to the membrane while contaminants pass through. Enzyme inhibitors are effectively removed with subsequent washes and pure DNA is eluted in a low-salt elution buffer (see The PAXgene Tissue DNA Procedure).

The PAXgene Tissue DNA Kit provides 3 protocols for purification of DNA from different starting materials:

  • Sections of PFPE tissue
  • PF tissue samples (without paraffin embedding)
  • Blocks of PFPE tissue samples

 

Automation

DNA purification using the PAXgene Tissue DNA Kit can be automated on the QIAcube, enabling:

 

Two protocols are available for automated purification from different starting materials:

 

Applications

The purified DNA is ready to use in a wide range of downstream applications (see Resources), including:

  • PCR, multiplex, long-range, and quantitative, real-time PCR
  • Southern blotting
  • SNP genotyping
  • Sequencing
