WebJan 16, 1991 · Primers for a polymerase chain reaction are prepared by treating a double-standard DNA fragment with an exonuclease. DNA is amplified in vitro by the polymerase chain reaction using such primers. Chromosomal genes are amplified by carrying out the inverted polymerase chain reaction using as a primer, a DNA fragment obtained by … WebPhosphorothioates have found their usefulness in the general area of oligonucleotide therapeutic applications. Initially this modification was introduced into the antisense methodology because of the nuclease resistance of the phosphorothioate linkage in comparison with that of the phosphate linkage …
WebApr 14, 2014 · Lambda exonuclease is used to hydrolyze the 5′-phosphoryl strand of double-stranded DNA. In a typical reaction, 1–2 µM amplicons are incubated at 37°C for 60 min with 1 U enzyme for every 5 pmol dsDNA. The enzyme is inactivated by heating at 70°C for 15 min. The single-stranded DNA is cleaned up on centrispin 20 size exclusion column. WebHere, based on lambda exonuclease (λ exo), for the first time, we propose the normally open (NO) and normally closed (NC) switching strategy with a unified signal transmission mechanism to build molecular circuits. Specifically, the opposite logic can be output with or without a single signal, and the state of the switch can be adjusted by the ...
