Product Description
BioChain’s cfPure® Cell Free DNA Extraction Kit is designed for rapid and efficient purification of circulating cell free DNA (cfDNA). The system utilizes silica-coated paramagnetic particles to purify cell free DNA from less than 1 mL to greater than 10 mL of serum or plasma. The buffers were developed to ensure efficient recovery of 100 bp – 500 bp DNA fragments in order to maximize recovery of cell free DNA. The recovered DNA is suitable for a wide range of down-stream applications, such as bisulfite sequencing, NGS, and qPCR.

Applications:
Extract high quality cell free DNA from plasma, serum, and urine for Next Generation Sequencing (NGS), Bisulfite Sequencing, PCR, qPCR, ddPCR and other demanding applications.
Advantages and Features:
Versatile: Extraction from <1mL to >10mL serum or plasma – in single tubes or 24- to 96-well plates
Automation Friendly: On both the KingFisher™ and liquid handling instruments, with extractions taking approximately 50 minutes
Time Efficient: Manual extraction protocol takes less than 75 minutes
Cost Effective: Competitive price <$3 per extraction from 1 mL plasma (List price for 250mL kit)
Elution volumes: Range from 15 µL to 50 µL
Rapid and Efficient Magnetic Bead-Based Protocol
The cfPure® protocol is rapid and easy, allowing users to process several samples in an hour or less and making it ideal for biomarker screening. BioChain has developed its own silica-coated magnetic bead technology, which is designed to efficiently recover low molecular weight cell free DNA during isolation. In addition to being easy to perform, and easy to automate, you can use less magnetic bead solution if you are purifying small amounts of plasma – saving you money. The key to successful analysis of cfDNA is to ensure efficient purification of smaller DNA fragments (100-500 bp). As Figure 1 shows, the cfPure® Cell Free DNA Extraction Kit does efficiently recover these important small fragments.
cfPure – A Scalable Cell Free DNA Extraction Kit:
Cfpure is designed to be a scalable kit (Fig. 2.). This means that you can use just the amount of beads and reagents that you need for your cfDNA extraction. This also means that the number of extractions per kit is dependent on the amount of sample you wish to purify DNA from. For example, if you are working with 1mL samples, our 100mL kit (Catalog # K5011610) can process up to 100 samples, and our 250 mL kit (Catalog # K5011610) can process 250 samples. If you are working with 10mL samples, our 100mL kit (Catalog # K5011610) can process up to 10 samples, and our 250 mL cell free DNA Extraction kit (Catalog # K5011625) can process 25 samples.
Benefits of cfPure® Magnetic Bead-Based Purification
Magnetic beads offer many benefits compared to other technologies for isolating cfDNA. Beads bind the DNA more efficiently than glass fiber filters, resulting in higher and more consistent yields. Additionally, because filters and vacuum manifolds are not used, there is no risk of cellular particulates clogging these items during the extraction process. This clogging issue is of particular concern with protein-rich, large-volume samples such as plasma that are commonly used in cfDNA studies.
cfDNA Validated with NGS by End Users
cfDNA extracted by cfPure® cfDNA Extraction kit is excellent for downstream applications such as NGS. In a third party study cfDNA was extracted from 10 ml’s of human plasma from 4 donors using BioChain’s cfPure® (B), Competitor T’s(T), and Competitor Q’s (Q, column-based) cfDNA extraction kits. Libraries were then constructed for each sample , and whole genome sequencing was performed . From the data analysis, three extraction methods did not show significant performance difference across the board: Insert size (Fig. 3.), Mapping rate, Whole genome coverage, Substitution rates and GC bias (Fig. 4.)
Reproducible and Efficient Recovery of cfDNA
Automation Friendly
cfPure® Cell Free DNA extraction kit is applicable on both the KingFisher™ (Fig. 5. ) and liquid handling instruments. With the KingFisher™ Flex and BioChain’s cfPure® Cell Free DNA Extraction kit can extract up to 96 one ml samples in 50 minutes, or 24 five ml samples in one hour.
Important Notes
In general, our original cfPure kit (catalog numbers K5011610, K5011625, and K5011625MA) performs best with higher yields and complete cfDNA capture when double-spun plasma that is free of contaminating white blood cells is used. However, if the plasma was not double-spun immediately upon collection or there is other gDNA contamination in the plasma, then we strongly recommend using this cfPure V2 kit instead. V2 will minimize the gDNA contamination in the final elution, although it should be noted that some of the cfDNA may also be lost.
