文献和实验Joining RNA Molecules with T4 DNA Ligase
Researchers interested in studying RNA structure and function or RNA-protein interactions are increasingly using site-specifically modified RNAs to probe sites of interest (1 ). In addition to expanding the repertoire of functional groups
Splint Ligation of RNA with T4 DNA Ligase
Splint ligation of RNA, whereby specific RNA molecules are ligated together, can be carried out using T4 DNA ligase and a bridging DNA oligonucleotide complementary to the RNAs. This method takes advantage of the property of T4 DNA ligase
Ligation of DNA with T4 DNA Ligase
recombination and DNA synthesis. DNA ligase from E. coli is a polypeptide with a molecular weight of 74,000 and is NAD-dependent. T4 DNA ligase is the product of gene 30 of the T4 phage, has a molecular weight of 68,000, and is ATP-dependent. Both enzymes
