    01a: Extract and Purify Higher Yields of Higher Quality DNA from Limited Input with Isotachophoresis
    The Purigen Ionic® Purification System uses isotachophoresis (ITP) to extract, concentrate and purify nucleic acid from biological samples. ITP is a gentle, microfluidic, process that separates nucleic acid from impurities using electrophoretic mobility.

    02a: Isotachophoresis Improves Nucleic Acid Extraction and Purification from FFPE Samples
    With a simplified workflow and separation based solely on the electrophoretic mobility of the molecules in a sample, Purigen’s Ionic Purification System offers an alternative for FFPE sample purification for NGS that has less risk of further damage to nucleic acids or bias toward specific fragment length or GC content.

    02b: Increased DNA Yield and Reduced PCR Duplicates Using the Ionic System
    FFPE tissue samples are known to produce low yields of nucleic acid that is often of a lower quality by comparison to nucleic acid from fresh frozen tissue, particularly samples that have been stored for several years or longer. When FFPE tissue is limited, conventional extraction and purification technologies may not produce enough high quality DNA to meet the recommended library preparation input requirements for next-generation sequencing (NGS).

    03a: Simultaneous, High-yield Extraction of DNA and RNA from FFPE Tissue
    Simultaneous extraction and purification of both RNA and DNA from FFPE tissue samples is critical to enable multiple downstream analyses from rare or limited samples. To avoid yield loss, most technologies use a serial isolation approach where DNA and RNA are separated after lysis by filtration or precipitation before entering separate purification workflows. This results in twice the number of purification steps per sample.
