Cell engineering technology

Research Content

1, animal and plant cells and tissue culture The most significant value is the rapid breeding of excellent plants and a large amount of preparation of metabolites. Animal plant cells and tissue culture can be divided into three levels of culture: cell culture, tissue culture and organ culture.

2, cell fusion uses natural or artificial methods to fuse two or several different cells (or protoplasts) into a cell for producing new species or lines (more plants, It is used in animals and produces monoclonal antibodies. Among them, monoclonal antibody technologies can utilize clonal hybridoma cell secretion height pure monoclonal antibodies, which have high practical value, have made great contributions in diagnosis and treatment.

3, chromosome engineering chromosome is a technique of adding, eliminating or replacing organisms in accordance with people's needs. It is mainly divided into two kinds of animal chromosome engineering and plant chromosome project. Animal chromosome project mainly uses methods for micro-operation of cells (such as micro-cell transfer methods, etc.) to achieve the purpose of metastasis genes. Plant cell projects mainly use traditional hybrids, backlink, etc. to achieve the purpose of changing chromosomes.

4, the technique of embryonic engineering is mainly to obtain some artificial animals required for some kind of artificial engineering technique for mammalian embryos. New technologies adopted by embryonic projects include embryonic segmentation techniques, embryonic fusion technology, ovary transplantation technology, in vitro insemination technology, embryonic cultivation, embryo transplantation and gender identification technology, embryonic frozen technology.

5, cell genetic engineering mainly includes cloning and transgenic technology. The former is mainly referred to as a non-propagation, such as animal clones refers to a hermition of a hermit of a genetic traits produced by a zero-generated reproduction. It has now been attracted in an animal husbandry, rare animal genetic resource protection and reproduction, and medicine. The latter refers to the integration of exogenous genes into the organism to obtain stable expression, and the gene can stably generate experimental techniques to future generations. It is the most effective way to change the genetic traits of species. It has been rapidly developed in the field of microorganisms and animals and plants.
