Abstract
The invention belongs to the technical field of biological engineering, and discloses a goat cell clone embryo culture solution and a culture method thereof. The goat cell clone embryo culture solution comprises a solution A and a solution B, wherein per liter of liquid A contains 0.2mg of ferrous nitrate, 350mg of potassium chloride, 100 to 120mg of citric acid, 100mg of monosodium orthophosphate and the balance DMEM high-sugar liquid culture media. The culture solution is characterized in that a DMEM culture medium and an M16 culture medium in the prior art are improved; the liquid A and the liquid B of the culture solution are prepared; then, the cells are cultured in different stages; the two-cell embryo number, the four-cell embryo number, the mulberry embryo number, the blastaea number and the survival number after the blastaea implantation into a matrix are high; the in vitro development rate of the goat fertilized ova are higher than those of DMEM culture media and M16 culture media.
Description
technical field [0001] The invention belongs to the technical field of bioengineering, and in particular relates to a goat cell cloned embryo culture solution and a culture method. Background technique [0002] Goats are an important economic animal that produces meat, velvet, milk and other economic products, especially goat milk, which has huge market potential. If high-quality genetic resources of goat breeds are obtained and maintained, it is necessary to improve the existing population and become a goat The urgent problem of large-scale farming. [0003] Embryo cloning is a method of cloning, the most commonly used is somatic cell cloning technology, which refers to the method of nuclear transfer, cell disassembly or cell recombination technology, the enucleation of oocytes as nuclear receptors, somatic cells or The nuclear plastid containing a small amount of cytoplasm is used as the nuclear donor, and the nuclear donor is transferred into the nuclear recipient to con...
