The authors of this paper describe Easi-CRISPR, a robust and efficient strategy for targeted DNA cassette insertion in mice. The international consortium of 7 research teams injected mouse zygotes with long single-stranded DNA donors (Megamer Single-Stranded DNA Fragments) and pre-assembled Cas9 ribonucleoprotein complexes (Alt-R crRNA, tracrRNA, and Cas9 nuclease), and obtained successful knock-in at 13 loci.
In order to operate the International Space Station (ISS) National Laboratory more like an Earth-based lab, NASA has developed a molecular biology suite for microgravity conditions called WetLab-2. WetLab-2 is composed of tools, reagents, and methods, which allow on-orbit processing of biological samples and real-time gene expression analysis in space.
This paper describes the results from the WetLab-2 validation experiments. Specifically, qPCR was performed on a concentration series of DNA calibration standards, and RT-qPCR with ZEN Double-Quenched Probes was conducted on RNA that had been extracted and purified (on-orbit) from frozen E. Coli and mouse liver tissue.
Research scientists from IDT and the Gurumurthy lab (University of Nebraska Medical Center) describe methods for genome editing with ribonucleoprotein RNP complexes, which contain chemically-modified, synthetic guide RNAs and recombinant Cas9 protein. RNP delivery methods are described for lipofection and electroporation in mammalian cells, as well as microinjection in murine zygotes, either with or without addition of single-stranded HDR template DNA.
