A Novel Plasmid-Based Co-Tethered Transcription Platform for High Yield, High Purity mRNA Synthesis Read more »

Kithmie MalagodaPathiranage, Ruptanu Banerjee, and Craig T. Martin, Nucleic Acids Research, 52(17), 10607-10618. 2024 Current approaches to RNA synthesis/manufacturing require substantial (and incomplete) purification post-synthesis. We have previously demonstrated the synthesis of RNA from a complex in which T7 RNA polymerase …

A New Approach to RNA Synthesis: Immobilization of Stably and Functionally Co-Tethered Promoter DNA and T7 RNA Polymerase Read more »

Kithmie MalagodaPathiranage and Craig T. Martin, Methods in Enzymology, 691, 209-222, 2023 T7 RNA polymerase is widely used to synthesize RNA of any length, and long-standing protocols exist to efficiently generate large amounts of RNA. Such synthesis, however, is often plagued …

A Simple Approach to Improving RNA Synthesis: Salt Inhibition of RNA Rebinding Coupled With Strengthening Promoter Binding by a Targeted Gap in the DNA Read more »

Kithmie MalagodaPathiranage, Elvan Cavac, Tien-Hao Chen, Bijoyita Roy, Craig T Martin Nucleic Acids Research, 51(6), e36 (12 pages) T7 RNA polymerase is commonly used to synthesize large quantities of RNA for a wide variety of applications, from basic science to …

High-salt transcription from enzymatically gapped promoters nets higher yields and purity of transcribed RNAs Read more »

Craig T. Martin and Joseph E. Coleman, Biochemistry 26, 2690-2696, 1987 Specific interactions between T7 RNA polymerase and its promoter have been studied by asimple steady-state kinetic assay using synthetic oligonucleotide promoters that produce a short five-basemessage. A series of …
