FFPE tissue and samples with a low abundance of high-quality nucleic acid represent a bottleneck in sample preparation workflows. Researchers and clinicians working with these samples often resort to labor-intensive methods in order to isolate sufficient
material for downstream analyses. However, such methods are not always successful in increasing yields and can introduce bias which further impacts the quality of downstream analysis.
Purigen Biosystems has recently launched the revolutionary Ionic® Purification System to help scientists overcome the sample preparation bottleneck with a simple, automated approach to nucleic acid purification using isotachophoresis. Isotachophoresis
separates and concentrates charged molecules in solution solely based on their electrophoretic mobility. Biological samples are gently lysed and added to the Purigen Ionic® Fluidic Chip. An electric field is then applied to the chip and the
nucleic acid is isolated in its natural, native form. The nucleic acid is not denatured or dehydrated, and there’s no binding to, or stripping from, fixed surfaces.The result is a higher yield of pure nucleic acid that is less fragmented
and free from bead or wash buffer contamination.
In this webinar, we will discuss downstream molecular analyses of RNA/DNA purified from FFPE samples, fresh-frozen tissue, and cultured cells using the Purigen Ionic® Purification System. The results from quality assessments and downstream NGS
will be emphasized.
- A new innovative approach to automated nucleic acid purification
- How to extract more DNA and RNA from challenging FFPE samples with more reliability and less effort by comparison to conventional extraction methods
