New RACE, a variation of RNA ligase-mediated-RACE (RLM-RACE) (Liu and Gorovsky 1993) departs from classic RACE (see 5'-End cDNA Amplification Using Classic RACE) in that an "anchor" primer is attached to the 5'-end of the mRNA before the reverse transcription step; hence the anchor sequence becomes incorporated into the first-strand cDNA if, and only if, the reverse transcription proceeds through the entire length of the mRNA of interest. - [Read 5'-End cDNA Amplification Using New RACE Protocol]
DNA ligations are performed by incubating DNA insert with linearized cloning vector in the presence of ligation buffer, rATP, and T4 DNA ligase. Roe. Univ. Oklahoma. - [Read DNA ligation with Linearized DNA]
Protocol for ligating plasmid and target DNAs in low-melting-temperature agarose. Ligation in low-melting-temperature agarose is much less efficient than ligation with purified DNA in free solution and requires a large amount of DNA ligase. The method is used chiefly for rapid subcloning of segments of DNA in dephosphorylated vectors and assembling recombinant constructs. - [Read Ligating Plasmid and Target DNAs in Low-melting-temperature Agarose Protocol]
The DNA Ligation protocol described here contains the steps required to join together using ligase enzyme both plasmid DNA and insert DNA fragments in order to create a new plasmid. This new ligated plasmid can be transformed after into competent bacteria to produce DNA for mini, midi or maxi-prep isolation.
