Abstract: Provided are an animal preparation method and use thereof. The method includes aggregating a tetraploid embryo with embryonic stem cells to form a new reconstructed embryo or chimera embryo, the tetraploid embryo being a tetraploid embryo developed to 2-cell stage. By aggregating a 2-cell tetraploid embryo with embryonic stem cells, problems of poor efficiency and poor stability of mice preparation using the tetraploid complementation technique as well as low efficiency when embryonic stem cells from pure line mice are used are alleviated, the birth rate of mice is improved to a level close to that of normal embryo transplantation, and embryos and adult mice can be directly prepared from stem cells for phenotypic research.

Abstract: The present disclosure describes a kit for peritoneal dialysis that includes at least two bags. The kit also includes an overwrap for accommodating the at least two bags. At least one bag of the at least two bags forms at least a portion of the overwrap. According to the present disclosure, it is advantageously possible to reduce the material consumption of the overwrap, lower the cost of the kit, and reduce the amount of the disposable waste.
