Frozen Embryos

Our company provides frozen 8-cell mouse embryos produced by vitrification (Nakao et al, 1997, Exp. Anim.46 : 231-234). They can be used as host embryos for chimeric mouse production that uses ES cells derived from pigmented mice, for nuclear transplantation, for investigating the conditions required for freezing and thawing work, and for practicing embryo manipulation. They can also be used for the quality control of culture fluid.


• Prompt delivery: 8-cell embryos of ICR mice, 100 embryos/tube, can be delivered immediately even in large quantities
• Quality assurance: we always check thawing results
• Provision of related reagents: you can also purchase reagents necessary for everything from thawing to culturing
• We attach thawing protocols for customers who wish them
• We can also deal with various customer requests for frozen embryos that are not from the ICR mouse strain or not in the 8-cell stage
