  • Publication number: 20250075220
    Abstract: An improved method of site directed mutagenesis on plasmids by PCR is described, where at least two mutations are added to the parts of the plasmid DNA by site direct mutagenesis. One mutation is an intended mutation, and the other mutation changes the function of the mutated plasmid from the function of the template plasmid. The functional change is one to allow reduction of the retention of non-integrated template DNA, even in the absence of wild type template digestion with DpnI.

  • Publication number: 20240392264
    Abstract: Taq DNA polymerase mutants exhibiting reverse transcriptase activity compared to wild type polymerase were engineered, characterized, and selected via polymerase chain reactions visualized via electrophoresis on agarose gels. Initial screening was followed up with probe-based qualitative, real-time PCR (qPCR) with a typical reverse transcription cycling protocol to detect specified ribonucleic acid (RNA) target sequences. The engineered variants can render robust cDNA from RNA target substrates and amplify that cDNA under standard reaction conditions without the assistance of added reverse transcriptase enzymes.

  • Publication number: 20240279626
    Abstract: Either wild type or mutant Serratia marcescens Nuclease (“SMN”) is engineered to display a C-terminal Chitin Binding Domain (CBD-tag), followed, at the C-terminus side of the CBD-tag, by a poly-histidine tag (His-tag), where the His-tag is preferably a 6-mer and preferably is preceded by a Gly-Ser linker, thereby generating a recombinant SMN protein that retains dual affinity tags (a CBD-tag and a His-tag) at the C-terminus, to make it easily removed from a reaction solution following digestion of nucleic acids in the reaction mixture. It can also be used for binding SMN to a solid support for use in nucleic acid digestion in a sample contacted with the solid support.
