Precise Sequential DNA Ligation on A Solid Substrate: Solid-Based Rapid Sequential Ligation of Multiple DNA Molecules

Ligation, the joining of DNA fragments, is a fundamental procedure in molecular cloning and is indispensable to the production of genetically modified organisms that can be used for basic research, the applied biosciences, or both. Given that many genes cooperate in various pathways, incorporating multiple gene cassettes in tandem in a transgenic DNA construct for the purpose of genetic modific...

Microinjection of Specific DNA Sequences

The mutant Paramecium tetraurelia cell line d48 is unable to express the serotype A protein on its surface. Although the A gene is intact in the micronuclei of d48, the A gene copies in the macronucleus contain a large deletion eliminating virtually the entire coding sequence. Previous studies showed that microinjection of a plasmid containing the entire A gene into the macronucleus of d48 perm...

Computer simulation of DNA ligation: determination of initial DNA concentrations favouring the formation of recombinant molecules.

A computer program was used to simulate the dynamic process of a ligation of DNA fragments. More specifically, the influence of the initial DNA fragments lengths and concentrations on the relative abundance of the various end-products was systematically investigated. Depending on the nature of the DNA extremities (asymmetric or symmetric, dephosphorylated or not), sets of initial conditions cou...

Selective enrichment of damaged DNA molecules for ancient genome sequencing.

Contamination by present-day human and microbial DNA is one of the major hindrances for large-scale genomic studies using ancient biological material. We describe a new molecular method, U selection, which exploits one of the most distinctive features of ancient DNA--the presence of deoxyuracils--for selective enrichment of endogenous DNA against a complex background of contamination during DNA...

Efficient DNA ligation by selective heating of DNA ligase with a radio frequency alternating magnetic field

We present a simple method for efficient DNA ligation utilizing the heat generation of ferromagnetic particles subjected to an ac magnetic field. We carry out the ligation of DNA fragments with cohesive ends using T4 DNA ligase immobilized on the surface of ferromagnetic particles. When a radio frequency alternating magnetic field is applied, ferromagnetic particles dissipate heat and DNA ligas...
