The problems such as obtained gene transfection efficiency of bottom plate is lower, and different document transfection efficiencies differ greatly.Based on this problem, it is necessary to existing
There is technology to improve.
Summary of the invention
It is traditional it is positive place tissue culture plate, be inverted the obtained gene transfection efficiency of ultrasonic probe exposing cell bottom plate compared with
It is low, the reason is that since the lipid microbubble of gas core easily swims in cell culture fluid surface, when forward direction places tissue culture plate,
The microvesicle and board bottom cell for carrying gene are there are certain distance, after ultrasound wave irradiation increases permeability of cell membrane, gene cannot and
When enter cell.
To solve the above-mentioned problems, the utility model provides a kind of combining ultrasonic targeted microbubble destruction technology mediation gene turn
The device of dye, tissue culture plate inversion can effectively improve gene transfection efficiency, provide safe and efficient gene delivery for gene therapy
Mode.
When tissue culture plate is inverted, microvesicle swims in cell peripheral, when ultrasound breaks up microvesicle, when open cells fenestra,
Gene is easier to enter intracellular.There is a necessary condition at this time, tissue culture plate must drain air after being inverted, otherwise air
It steeps oneself-meeting and floats up to cell peripheral, completely cut off microvesicle and cell, make the reduction of gene transfection efficiency instead.
The purpose of this utility model is achieved through the following technical solutions: a kind of combining ultrasonic targeted microbubble destruction technology

In some technical solutions, the table top of the lifting platform (5) is equipped with anti-skidding silicagel pad.
In some technical solutions, the iron clamp (3) is circle, and one layer of rubber layer is wrapped up in outside.
The utility model uses silica gel plug encapsulated cell culture plate, fits closely silica gel plug with liquid level in cell hole, arranges
Air success rate is high to the greatest extent, easy to operate, guarantees the close contact of microvesicle and cell after tissue culture plate is inverted.
Iron stand of the utility model using lifting platform and adjustable height and direction, the essence of achievable cell hole and probe
Really fitting.
The utility model uses 12 orifice plates, and single hole is bonded completely with the ultrasonic probe shape, thin when can make ultrasound wave irradiation
Born of the same parents are uniform by shining, and ultrasonic wave is avoided to interfere other cell hole results.
Beneficial effect
It places tissue culture plate with conventional forward to carry out outside ultrasonic in combination microbubble body compared with cytogene transfection, this is practical new
