We investigated the effects of 5'-end truncated CRISPR RNA-guided Cas9 nuclease (tru-RGN, 17/18 nucleotides) on genome editing capability in NIH/3T3 cells, and its efficiencies on generating Factor VII (FVII) gene-knockout (KO) mice. In cultured cells, RGNs on-target editing activity had been varied when gRNAs was truncated, higher at Site Two (tF7-2 vs.(More)
The aim of this study was to assess modified droplet vitrification (MDV) for the cryopreservation of early developmental mouse embryos. Mouse embryos were equilibrated in holding solution for 3 min followed by immersion in vitrification solution for 30-45 s, and then three embryos per 3-μL vitrification droplet were directly dropped into liquid nitrogen.(More)
