NUCLEIC ACID EXTRACTION Magnetic cfDNA Extraction Kit Bottle format 96B format CE, FDA, NMPA Registered 1. Description EmerTher® Magnetic Circulating Free DNA Extraction Kit is used for extracting circulating free DNA (cfDNA) from biological samples (e.g. plasma) with high efficiency and is an ideal sample preparation kit for Noninvasive Prenatal Testing (NIPT) and liquid biopsy. The experiment procedure is simple and efficient: 1) add sample to a lysis-binding solution to enable the binding of cfDNA to magnetic beads; 2) apply magnetic force enabling easy wash of the beads with buffers; 3) elute cfDNA from the beads using an elution solution. Purified cfDNA can be directly used for gene sequencing (such as NIPT or liquid biopsy), library construction, and other downstream applications. 2. Features High throughput: Fast extraction, complete in < 1 hr Flexible sample volume: excel at extraction of a trace amount of cfDNA from samples (200 µL to several mL). Sample extraction process is scalable for large volumes. CfDNA peak resides at ~170-200 bp with high purity and high concentration Automation: compatible with a variety of automated magnetic bead processors; pre-filled plates are provided if needed.
