  • Cloning and characterization of cDNAs encoding V-H and V-L of a monoclonal anti-CEA antibody (CEA 79) cross-reactive with NCA-95 and generation of a single-chain Fv molecule (scFv)
    'University of Tartu', 2019
    Co-Authors: Jh Chung, Sj Choi, Hj Him, Ij Kim, Ih Choi, Sd Lee, Sh Ryu, Pg Suh, Hk Chung
    Abstract:

    We cloned complementary DNA (cDNA) encoding the variable regions of heavy chain (V-H) and of light chain (V-L,) of a monoclonal anti-carcinoembryonic antigen (CEA) antibody cross-reactive with nonspecific cross-reacting antigen-95 (NCA-95), which had been previously prepared and designated as CEA 79 (gamma(2a),,, kappa). From these cDNAs, a Phagemid expression vector for the CEA79 single chain variable fragment (scFv) was generated. Enzyme-linked immunosorbent assay (ELISA), competitive ELISAs, and Western blotting confirmed that the scFv displayed on the surface of the bacteriophage had retained affinity for CEA and NCA-95. We then determined the nucleotide sequences of the cloned cDNAs for V-H, and V-L,. The sequence analysis revealed that V-H, and V-L, of the CEA 79 antibody represent new members of the mouse heavy chain subgroup "miscellaneous" and the kappa light chain subgroup "V", respectively.X1

  • Construction of a novel Phagemid to produce custom DNA origami scaffolds
    Synthetic biology (Oxford England), 2018
    Co-Authors: Parsa M. Nafisi, Tural Aksel, Shawn M. Douglas
    Abstract:

    DNA origami, a method for constructing nanoscale objects, relies on a long single strand of DNA to act as the "scaffold" to template assembly of numerous short DNA oligonucleotide "staples". The ability to generate custom scaffold sequences can greatly benefit DNA origami design processes. Custom scaffold sequences can provide better control of the overall size of the final object and better control of low-level structural details, such as locations of specific base pairs within an object. Filamentous bacteriophages and related Phagemids can work well as sources of custom scaffold DNA. However, scaffolds derived from phages require inclusion of multi-kilobase DNA sequences in order to grow in host bacteria, and thus cannot be altered or removed. These fixed-sequence regions constrain the design possibilities of DNA origami. Here we report the construction of a novel Phagemid, pScaf, to produce scaffolds that have a custom sequence with a much smaller fixed region of only 381 bases. We used pScaf to generate new scaffolds ranging in size from 1,512 to 10,080 bases and demonstrated their use in various DNA origami shapes and assemblies. We anticipate our pScaf Phagemid will enhance development of the DNA origami method and its future applications.
