High-Efficiency Detection of Low-Frequency Alleles in Cell-Free DNA

K. Shazand, J. Ning, E. Ranghini, A. Popkie, and J.P. Jerome The ability to detect rare alleles is key to the discovery and characterization of mutations in cancer research. These mutations are found at low frequencies, mainly because of tumor heterogeneity and tumor DNA dilution in the germline background. Cell-free DNA (cfDNA) in plasma provides… Read more »

ThruPLEX™ Technology Repairs Damage and Amplifies Small Amounts of Biofluid DNA for NGS, Microarrays and PCR

M. Mastronardi, T. Tesmer, E. Kamberov, J. Langmore Biofluid Challenges: Biofluids, including plasma, serum, urine and CSF, contain valuable biomarkers that are used in research and diagnostics. These matrices present many challenges to traditional sample preparation methods. Biofluid DNA is fragmented (100-200 bp) and very dilute (e.g., 1-20 ng/mL of plasma). Additionally, the biomarker-containing DNA… Read more »

NovaPlex™ for Amplification and Analysis of Nucleic Acids from Formalin-Fixed, Paraffin-Embedded Tissue

T. Tesmer, M. Mastronardi, E. Kamberov, J. Langmore The fixation of human tissues with formalin, and their subsequent embedding in paraffin, has been a routine method of collecting and preserving surgical specimens for many years. These formalin-fixed, paraffin-embedded (FFPE) tissues represent an extremely valuable resource for investigators interested in determining both the pattern of gene… Read more »
