Does your cfDNA extraction process affect the Limit of Detection (LOD) of a particular gene target? Our new products, cfDNA Extraction Sensitivity Panels and Extraction Low Positive Controls, can help your research and development for liquid biopsy assays.
NEW PRODUCTS: cfDNA EXTRACTION SENSITIVITY PANELS & CONTROLS
The Extraction Sensitivity Controls can help by monitoring plasma cfDNA loss, determining how low the absolute plasma cfDNA number of copies can be reliably extracted, and standardizing QC workflow for plasma cfDNA extraction process.
Two extraction sensitivity panels and two extraction low positive controls are currently available as catalog products. Also, the customized panels and controls can be built per requirements of customer. For the price and availability of catalog and customized products, please send an email inquiry to info@anchormolecular.com.
Extraction Sensitivity Panel 1 (for variant allele frequency sensitivity)
- DNA-free plasma spiked with cell-derived DNA fragment containing 23 variants at 0, 0.1, 0.3, 1, and 3% average AF in a constant 20 ng/ml fragmented total gDNA background. The list of 23 variants is below. Each member of the panel can be separately purchased.

Extraction Sensitivity Panel 2 (for gDNA ng/ml)
- DNA-free plasma spiked with increasing concentration of total gDNA fragments at 0, 0.3, 1, 3, and 10 ng/ml. Customized controls at specific ng/ml can be ordered.
Extraction Low Positive Controls
- DNA-free spiked with fragmented gDNA at a fixed low concentration (3ng/ml).
