英文摘要
The broad, long term objective and specific aims of the fasttrack SBIR research are to create a
reagent, RecombiRED, for use in microinjection of embryos for identifying a subset of embryos
as recombination competent injections. The ability to quickly identify genome editing events in
an embryo allows researcher to quickly make precision animal models of human disease states.
Precise animal models allow for greater scientific understanding of a human disease and
provides a robust platform for drug discovery screening. The RecombiRED reagent relies on
induced fluorescence in response to activation of homologous recombination repair within the
embryo. Detection of homologous recombination repair in injected embryos with RecombiRED
allows animal husbandry and further screening efforts to be restricted to a subset of embryos by
up to 100x for having a desired precise knockin of new genetic material at a specific genetic
locus. The phase I research adapts a the RecombiRED reagent developed in C . elegans model
organism to have the appropriate expression control elements enabling sufficient activity in
zebrafish embryo. In Phase II, the additional research further optimizes parameters of the
RecombiRED reagent to minimize false positive and false negative readouts, which then allows
maximal forecasting of targeted genome edit events. Finally, a set of 15 realworld transgenesis
projects are used as premarket betatest to demonstrate the ubiquity and robustness of the
RecombiRED for simplifying discovery of genome editing in the creation of animals models for
use in drug discovery.
