Ionic® Cells to Pure DNA - Low Input

Maximum Recovery from Low Cell Numbers

Higher yields of high quality DNA from a few as 10 cells


Get More from Low Cell Counts

The Ionic system consistently recovers DNA in yields near the theoretical maximum from cultured or sorted cell samples in amounts ranging from 100,000 cells down to just 10 cells. Regardless of the input amount, the workflow for the Ionic Cells to Pure DNA – Low Input Kit is the same and does not require the use of carrier RNA.

  • Optimized for Low Input – Higher yields from samples containing as few as 10 cells
  • Improve Quality – More amplifiable DNA from low inputs without using carrier RNA
  • Improve Reliability – Linear increase in yield as cell count increases

Ionic® Purification System for Cells

The Ionic Purification System from Purigen Biosystems uses isotachophoresis (ITP) to extract, purify, and concentrate genomic DNA from cells and and FFPE. Since nucleic acids remain in their native form, not denatured or dehydrated, the Ionic system is ideal for challenging samples with limited starting material or low-quality material.

Higher Confidence in Low Input Samples

1.5X - 2X More DNA from Low Cell Numbers


FIGURE 1: DNA extracted and purified from 3 cell lines at input amounts of 10, 100, 1000, 10,000 and 100,000 cells using the Ionic system and a commercially available column based kit. Ionic system yields increase linearly as input amount increases and range from 1.5x to 2x those of the column kit. Yield of DNA recovered on the Ionic system is 80-90% of theoretical maximum yield.


Less Fragmentation vs. Column-based Kits

Purigen Isotachophoresis Technology

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 which applies an electric field to isolate nucleic acid in its natural, native form.
