Efficient production of genetically modified mice of the same age!
We produce genetically modified mice with uniform age (date of birth) and quality at your desired timing using in vitro fertilization and embryo transfer methods. We will produce and supply mice of the same age according to your experimental plan. 【Features】 ■ Ability to obtain a large number of mice of the same age or day of life ■ Possibility of obtaining offspring from mice that are difficult to breed through natural mating ■ By combining in vitro fertilization, we can efficiently produce homozygous individuals or mice with the desired genotype. 【Please use this service in the following cases】 ■ There are only a few males and females, but a large number of mice are needed for experiments ■ A large number of individuals of the same age are required for drug evaluation or behavioral analysis ■ A large number of mice with synchronized age or day of life are needed for the identification of trace components in vivo *For more details, please refer to the PDF document or feel free to contact us.

basic information
After in vitro fertilization, the number of offspring obtained varies depending on the number of embryos implanted. ■ Business Model: In the case of obtaining 150 mice Using the mice entrusted to us, after in vitro fertilization, we will implant approximately 200 morphologically normal 2-cell stage embryos into the oviducts of 30 surrogate mice. After weaning, the surrogate mice that cohabitated with the offspring will undergo microbiological testing as monitoring mice, and after confirming that the specified items are negative, we will deliver them. Number of offspring: Approximately 150 mice (about 75 of each sex) *For more details, please refer to the PDF document or feel free to contact us.
