Problems solved by technology

On the other hand, with the continuous development of genomics, transcriptomics, proteomics, metabolomics and other technologies, as well as the continuous improvement of gene editing technology, the research on gene function and molecular breeding of crabs is in great need of its cell lines. At present, the cell culture technology of crabs is immature, and the primary cell culture of Eriocheir sinensis still has many problems such as poor cell shape, low survival rate, short survival time, seldom splitting, and difficult to pass down generations, which seriously affects the quality of Eriocheir sinensis. With the development of crab gene function research and molecular breeding technology, it is necessary to find a method of blood cell culture medium preparation that can improve the survival rate of blood cells and protect the cell shape, which has important scientific research significance and practical value.

Embodiment 1

[0059] 1) Preparation method of culture medium

[0060] Weigh 1.5g of calcium chloride, 1.5g of sodium chloride and 2g of glucose respectively. Measure 1L of TC-100 basal medium, put the above-mentioned weighed substances into TC-100 medium, add 5% 1×PBS and mix well, use an osmometer to adjust the osmotic pressure to 1000mOsm / kg, and then Filter through a 0.22 micron bacterial filter. Add 1% penicillin-streptomycin double antibody solution.

Abstract

The present invention belongs to the technical field of cell culture and particularly relates to a Chinese mitten crab blood cell culture medium and a culturing method. The Chinese mitten crab blood cell culture medium comprises a basic culture medium and added components, wherein the basic culture medium is selected from a TC-100 basic culture medium; and the added components and concentrations thereof are as follows: 1%-10% of a buffer solution, 1g / L-2g / L of calcium chloride, 1g / L-2g / L of alkali metal chloride, 1.5g / L-2.5g / L of glucose and 1%-1.5% of antibiotic. The culture medium significantly improves survival rate of Chinese mitten crab blood cells in in-vitro culture and prolongs duration of the blood cell culture in vitro, and the blood cells cultured in vitro can maintain good cellmorphology.

Description

technical field [0001] The invention belongs to the technical field of cell culture, and in particular relates to a culture medium of Chinese mitten crab hemocytes and a culture method thereof. Background technique [0002] Chinese mitten crab (Eriocheir sinensis), commonly known as "river crab", is widely distributed in my country and is an important cultured crab in my country, with high economic value and deep cultural heritage. In recent years, with the continuous expansion of the scale of Chinese mitten crab breeding, the continuous increase of the breeding area and breeding density, the annual increase in production has caused the continuous occurrence of related diseases and seriously affected the health of the Chinese mitten crab breeding industry. steady development. Hemocytes play an important role in the host immune response, including recognition, phagocytosis, melanization, cytotoxicity, and intercellular information transmission. Blood cells cultured in vitro...
