The Charm-Pure™ FFPE gDNA Isolation Kit is designed and optimized for easy and fast isolation of high-quality gDNA from FFPE tissues. Charm-Pure system employs special turbo-binding membranes as selective nucleic acid captures in a familiar column format to efficiently extract gDNA from FFPE sample tissues with higher yield and purity than conventional silica membrane. Genomic DNA molecules can specifically interact
with the turbo-binding membrane in the extraction buffer, while proteins and other
contaminants are not bound and remain in the solution and passed through. After washing the column with washing buffer to remove
unbound material, the purified gDNA can be easily eluted in 10 mM Tris Elution
Buffer or water. The novel sample buffers and process in this kit can also
efficiently remove nucleic acid chemical modifications introduced by formalin
fixation step in tissues embedding process. The modification-removed DNA
molecules are better substrates being ready for use in downstream applications,
such as restriction digestion, primer extension, PCR, whole genome
amplification (WGA) and other genomic analysis.
