  • Publication number: 20120309000
    Abstract: The present disclosure provides an isolated DNA molecule derived from Mycobacteria having a DNA mismatch repair function represented by a nucleic acid sequence as disclosed in SEQ ID NO: 1 or 2. Also provided is a promoter sequence having SEQ ID NO: 3, and a recombinant vector comprising the isolated DNA of the present disclosure and a promoter operatively linked to the DNA molecule. The isolated DNA molecule of the present disclosure is classified as MutS4A and MutS4 and confers cells with resistance to UV and macrophages when transformed into the cells. Further it increases the frequency of homologous recombination and the genetic stability of a heterologous plasmid in cells.

  • Patent number: 8318438
    Abstract: We describe examples using aptamers for capturing and reporting the presence of a target, such as a pathogen. Examples described here include a set of aptamers that are specific to F. tularensisis. Other examples described here include an Aptamer-Linked Immobilized Sorbent Assay (ALISA) and dot blot assay. An example of a method provided here comprises: providing a set of DNA sequences that exhibit high binding affinity to target antigen, placing the DNA sequences in a sandwich aptamer-linked immobilized sorbent assay (ALISA), contacting the DNA sequences with a sample, and detecting whether the target is present in the sample. Some alternative implementations may include dot blots and different reporters. Quantum dot sandwich assays and quantum dot de-quenching reporters can be used.

  • Publication number: 20120282624
    Abstract: This invention includes a process for the identification and validation of a neutral polynucleotide integration site within the S. spinosa genome. In addition, the invention includes the use of the neutral site and methods for the integration of a polynucleotide containing a gene expression cassette, which is stably maintained and expressed over subsequent generations. The invention includes neutral integration sites that can be disrupted without negatively impacting spinosyn production, growth or other desired metabolic characteristics.
