Genomic DNA from diverse sample types for genetic workflows and biobanking
The high, archival integrity of nucleic acids obtained with chemagic technology is ideal for biobanks and testing laboratories. The chemagic separation technology automates the efficient extraction of high molecular weight (HMW) DNA, enabling successful application in diverse downstream assays for genetic testing such as HLA typing1 for donor screening, SNP arrays for pharmacogenetics2, MLPA for copy number detection3, NGS from dried blood spots for newborn research4 and long read sequencing in genetic research5.
“More than 10 years ago, we chose chemagen instruments and reagents for isolating DNA from blood or buccal swabs. After performing HLA genotyping on over 10 million samples, we remain extremely satisfied with this decision and the consistent performance.”

cfDNA from liquid biopsies
cfDNA from liquid biopsies
The unique large volume processing capability of chemagic instruments and high specificity of M-PVA Magnetic Beads combine to boost extraction yields of cfDNA from liquid biopsies, increasing chances of detection downstream. Easily scale from low to high throughputs and manual to automated kit options. chemagic cfDNA extraction has been used to support the clinical research of colorectal6, lung7, prostate and anal cancer8 with downstream methods including digital PCR and pan-cancer NGS panels.
“We use cfDNA extracted with chemagic™ technology in digital droplet PCR (ddPCR) assays to support research of colorectal cancer, lung cancer, and anal cancer (based on HPV cfDNA detection) with a sample to result turnaround time down to 24 h.”

DNA from frozen/FFPE tissue, blood, or bone marrow
To support the growing demand, nucleic acid extraction from blood, bone marrow cells, or tumor tissue that is either fresh, frozen, or formalin-fixed, paraffin-embedded (FFPE) is often performed. The chemagic kits consistently produce high-quality, NGS grade DNA and RNA from these sample types and more. Commonly cited downstream applications include RT-PCR, methylation arrays, MLPA and pan-cancer NGS panels9,10.

miRNA from plasma, serum, or exosomes
Despite the small size and low concentrations of cell free circulating microRNA (miRNA), the chemagic miRNA kits obtain high, consistent yields comparable to manual methods with only 10 minutes of hands-on time. Suitable for plasma, serum, extracellular vesicles and saliva, miRNAs obtained have been analyzed by rtqPCR and NGS.
“We have started the testing of cfRNA isolations with our chemagic 360 instrument – the RNA yields appear fine from different plasma and serum samples; thus we look forward to use the kit for high throughput applications.”

Pathogen nucleic acids from body fluids
Pathogen nucleic acids from body fluids
Fast turn-around times, diverse sample type processing and high, consistent yields make chemagic nucleic acid kits with chemagic instruments the choice for many research labs working on infectious diseases. Automated extraction workflows from gram positive and negative bacteria, intra and extracellular viruses, yeast, funghi, and protozoa have been performed from body fluids like saliva, sputum, serum, plasma, lavage, urine, semen, amniotic fluid as well as swabs in various transport media. Challenging sample types such as stool, ticks, cultures, and wastewater have also been processed. Applications cited have been wide-ranging from blood-borne parasite screening to wastewater surveillance of infectious agents12,13,14.
“The chemagic 360 instrument has been functioning well, satisfying the requirements of our COVID-19 testing (4000 samples/day) and meeting our expectations for quality and reliability.“
