High Efficiency Hydrodynamic DNA Fragmentation in a Bubbling System

High Efficiency Hydrodynamic DNA Fragmentation in a Bubbling System

DNA fragmentation down to a precise fragment size is important for biomedical applications, disease determination, gene therapy and shotgun sequencing. In this work, a cheap, easy to operate and high efficiency DNA fragmentation method is demonstrated based on hydrodynamic shearing in a bubbling system. We expect that hydrodynamic forces generated during the bubbling process shear the DNA molec...

High Fragmentation Characterizes Tumour-Derived Circulating DNA

BACKGROUND Circulating DNA (ctDNA) is acknowledged as a potential diagnostic tool for various cancers including colorectal cancer, especially when considering the detection of mutations. Certainly due to lack of normalization of the experimental conditions, previous reports present many discrepancies and contradictory data on the analysis of the concentration of total ctDNA and on the proportio...

High-throughput On-chip Dna Fragmentation

In this paper we report a high throughput clog-free microfluidic deoxyribonucleic acid (DNA) fragmentation chip that is based on hydrodynamic shearing. Genomic DNA has been reproducibly fragmented with 2-10 kbp fragment lengths by applying hydraulic pressure ΔP across micromachined constrictions in the microfluidic channels. The utilization of a series of constrictions reduces the variance of t...

High-efficiency cloning system for versatile adaptation of DNA fragments.

Recombinant DNA vectors are fundamental tools in molecular biology and genetic engineering. One of the problems frequently encountered in vector construction is the lack of compatible restriction sites between the vectors and the DNA inserts. The conventional approach to solve this problem is to make the DNA fragments blunt-ended (3,4,12) or to add linkers or adaptors (10,11,14) before ligation...
