BEAMing, which stands for beads, emulsion, amplification, magnetics, is a highly sensitive digital PCR method that combines emulsion PCR and flow cytometry to identify and quantify specific somatic mutations present in DNA. See more BEAMing begins with the isolation of DNA from a patient’s blood or plasma sample. Target regions of the purified DNA undergo a pre-amplification step with conventional PCR utilizing primers of known sequences … See more In the late 1990s, Vogelstein and Kinzler coined the term “digital polymerase chain reaction” when conducting research into somatic mutations associated with and potentially causative for colorectal cancer. A fundamental challenge that digital PCR was designed to … See more BEAMing is often used in cancer research to conduct assessments of circulating tumor DNA (ctDNA), also known as a liquid biopsy. It also allows for the quantification of a sample’s mutant fraction, which can be tracked over time using serial plasma measurements. … See more WebJan 20, 2024 · DNA is reported in genome equivalents, with one genome equivalent being one haploid human genome weighing 3.3 pg. Circulating tumor-associated mutations in fresh plasma DNA (ctDNA), collected at baseline, were detected by BEAMing (Beads, Emulsions, Amplification, Magnetics) by Sysmex Inostics GmbH .
