Abstract

The invention provides a plate cover structure of a cell culture plate. The volume coefficient of dissolved oxygen of the cell culture plate can be improved, high-density cultivation is achieved, the expression quantity of a protein product is increased, and cross contamination of a culture solution can be effectively avoided. The plate cover structure of the cell culture plate comprises a plate cover, wherein an anti-fouling membrane, a waterproof membrane and a silica gel plate are orderly arranged inside the plate cover from top to bottom; a plurality of culture deep holes are evenly distributed on the cell culture plate. The plate cover structure is characterized in that a pipe body is inserted on the plate cover corresponding to each culture deep hole; the culture deep holes are communicated with the external part of the cell culture plate by the pipe body; the pipe body comprises a breather pipe, an exhaust pipe and a feeding pipe.

Description

The plate lid structure of Tissue Culture Plate
Technical field
Patent of the present invention relates to cell culture apparatus technical field in biology, relates in particular to the deep hole culture plate that cell cultures is used, and is specially the plate lid structure of Tissue Culture Plate.
Background technology
Along with molecular biological development, the heterogenous expression technology of albumen is ripe and be widely used gradually.The expression of foreign protein need to be selected suitable expressive host and Expression element, and this just need to build huge expression library, therefrom selects preferably representation aids box.Tissue Culture Plate can utilize less nutrient solution to carry out the screening of high-flux cell cultivation and bacterial classification, cell strain and expression library, has fast, high-throughput, the feature such as cost-saving.And in the expression process of Study of Exogenous albumen, as antibody, enzyme, should be to cultivate to raise the efficiency to obtain again enough albumen and carry out analyzing and testing by corpusculum, this just need to further realize high-density culture.
The corpusculum of existing fermentor tank Sub-scale is that its volume dissolved oxygen coefficient of culture apparatus is little, has limited the high-density culture of bacterial classification or cell, and has reduced protein product expression amount.
Summary of the invention
For the problems referred to above, patent of the present invention provides the plate lid structure of Tissue Culture Plate, and it can improve the volume dissolved oxygen coefficient of Tissue Culture Plate, realizes high-density culture, increases protein product expression amount, and can effectively avoid nutrient solution crossed contamination.
Its technical scheme is such, the plate lid structure of Tissue Culture Plate, comprise plate lid, in described plate lid, from top to down anti-soil film, waterproof membrane and silica-gel plate be installed successively, on Tissue Culture Plate, be evenly equipped with some cultivation deep holes, it is characterized in that: corresponding cultivate deep hole described in each, described plate covers and is fitted with body, described body is by the outside UNICOM of described cultivation deep hole and described Tissue Culture Plate, and described body comprises ventpipe, vapor pipe and feed supplement pipe.
It is further characterized in that:
Be positioned at the below of the nutrient solution liquid level of described cultivation deep hole, ventpipe is provided with baffle plate, described baffle plate is provided with four, and circumferentially uniform along ventpipe, adjacent two described baffle plates are arranged along ventpipe dislocation, two relative described baffle plates are arranged in parallel in described ventpipe direction, and the ventpipe of one end, plate lid outside is connected with extraneous gas supply line;
Be positioned at described plate lid outside, described feed supplement pipe is provided with branch road, and described branch road quantity is more than or equal to 2;
Described branch road is provided with three, and three branch roads are connected with the pipeline of extraneous nutrient solution, acid solution, alkali lye respectively, by outer bound pair nutrient solution, are realized pH regulator and are added the feed supplements such as nutrient solution;
The lower surface of described vapor pipe and described feed supplement pipe is positioned at the top of the nutrient solution liquid level of described cultivation deep hole, does not contact with nutrient solution.
Adopt after patent growth plate of the present invention lid, its beneficial effect is: the ventpipe covering by plate can provide thalli growth necessary oxygen to enough in nutrient solution, realizes high-density culture, and improves protein product expression amount; Metabolism waste gas and the oxygen of underusing are discharged by vapor pipe; By supplemented medium and nutritive substance in feed supplement Guan Kexiang nutrient solution, add acid or alkali and regulate nutrient solution pH, can pass through the control of exterior tubing, flow pump, realize the dropping of microlitre level; Anti-soil film in plate lid plays and prevents that miscellaneous bacteria, dust etc. from polluting the effect of fermented liquid, and waterproof membrane plays the effect that prevents nutrient solution moisture evaporation, and silica-gel plate can effectively prevent the crossed contamination between culture hole; Under vibrator provides certain rotating speed and eccentricity effect, the baffle plate arranging on ventpipe plays the effect of smashing bubble in nutrient solution, oxygen is dissolved in nutrient solution, has improved the volume dissolved oxygen coefficient of Tissue Culture Plate, and the effect that nutrient solution is played stirring, mixed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is assembly structure schematic diagram of the present invention.
Embodiment
Patent of the present invention be take the structure of 24 hole depth well culture plate plates lids and is described as example, the structure of patent of the present invention is not limited to 24 deep hole growth plate lids, be equally applicable to the growth plate lid of 48 hole depth well culture plate plate lids, 96 hole depth well culture plate plate lids and other hole bit quantity, equally, the structure of patent of the present invention is applicable to the plate lid of the culture plate of position, different shapes hole.
As Fig. 1, shown in Fig. 2, the plate lid structure of Tissue Culture Plate, comprise plate lid 1, in plate lid 1, anti-soil film 2 is installed from top to down successively, waterproof membrane 3 and silica-gel plate 4, on Tissue Culture Plate, be evenly equipped with some cultivation deep holes 9, wherein, in Fig. 2, only illustrate one and cultivate deep hole, corresponding each cultivation deep hole 9, plate covers and is fitted with body, body will be cultivated the outside UNICOM of deep hole and Tissue Culture Plate, body comprises ventpipe 6, vapor pipe 5 and feed supplement pipe 7, be positioned at nutrient solution liquid level 11 belows of cultivating deep hole 9, ventpipe 5 is provided with baffle plate 10, baffle plate 10 is provided with four, and circumferentially uniform along ventpipe 5, adjacent two baffle plates are arranged along ventpipe dislocation, two relative baffle plates are arranged in parallel in ventpipe direction, be positioned at plate and cover 1 outside, feed supplement pipe 7 is provided with three branch roads 8, three branch roads can be respectively and extraneous nutrient solution, acid solution, the pipeline of alkali lye is connected, the lower surface of vapor pipe 5 and feed supplement pipe 7 is positioned at nutrient solution liquid level 11 tops of cultivating deep hole 9.
