Description
Technical field
The present invention relates to the device of ELISA is applied to during a kind of scientific research, more particularly to a kind of push type ELISA loadings dress
Put.
Background technology
Enzyme-linked immunosorbent assay (ELISA), is one of common molecular biology experiment, is widely used in school and scientific research
Mechanism, its principle is, in surface of solid phase carriers, to make the antigen-antibody reaction that enzyme is marked solid by known antigen or antibody absorption
Phase surface is carried out, and the technology can be used to detect macromolecular antigen and specific antibody etc., easy with quick, sensitive, easy, carrier
The advantages of standardization.Conventional ELISA kit mostly is 96 orifice plates, when large sample is used for the experiment to be detected, from loading
First hole takes longer, error increase to last hole, cannot more ensure that the reaction time in every hole is consistent, greatly interference
Experimental result；In addition to content added by the every hole of standard items and sample is different, a remaining anti-working solution, enzyme labelled antibody work
Liquid, substrate working solution and last terminate liquid, are the content liquid such as every hole equivalent.Therefore, this device is designed, realizes same content
Deng quantity of fluid while add, greatly shorten loading time, be more beneficial for reducing the experimental error that causes of manual operation, it is right
The efficiency and accuracy for improving experiment plays strong impetus.
The content of the invention
The purpose of the present invention is the problems such as having unstability, longer consuming time, waste of resource for existing operation, is carried
For a kind of push type ELISA sampling devices.
The purpose of the present invention is achieved through the following technical solutions：A kind of push type ELISA sampling devices, the device bag
Include multiple loading pipes and outrigger；Outrigger is provided with multiple and loading pipe front end size identical hollow hole, and hollow hole is arranged in matrix,
It is corresponding with 96 orifice plates；The front end of loading pipe is embedded in hollow hole；The loading pipe includes external sleeve pipe, piston-in-sleeve, set
Head base, check valve sheet；Piston-in-sleeve one end is located in external sleeve pipe, is coordinated with external sleeve interference, and the other end is extended to
Outside external sleeve pipe；Piston-in-sleeve extension in all loading pipes is highly consistent；External casing part is provided with check valve sheet, single
It is the accommodation space for treating loading liquid for storage to valve block lower section.External its lower end is sealed by pullover base.
Further, also including pressing plate, pressing plate is placed in piston-in-sleeve top.
The invention has the beneficial effects as follows：Carry out method of operating when ELISA is tested for current scientific research to be integrated and weighed
New design, is assembled using current scientific and technological achievement, and efficiency and uniformity can be improved in process of scientific research, and is saved into
The waste of sheet and reduction resource, it is adaptable to which each universities and colleges and scientific research institution carry out experimental implementation, it is easy to promote.

Fig. 1 is the structural representation of loading pipe；
Fig. 2 is the loading schematic diagram of the present invention；
Fig. 3 is the structural representation of outrigger；
In figure, external sleeve pipe 1, piston-in-sleeve 2, pullover base 4, check valve sheet 5, loading liquid 6, pressing plate 8,96 are treated
Orifice plate 9, outrigger 10, hollow hole 11.
Specific embodiment
As Figure 1-3, a kind of push type ELISA sampling devices, the device is made up of multiple loading pipes and outrigger 10；Institute
Loading pipe is stated including external sleeve pipe 1, piston-in-sleeve 2, pullover base 4, check valve sheet 5；Outrigger 10 is provided with multiple and loading pipe
Front end size identical hollow hole 11, hollow hole 11 is arranged in matrix, corresponding with 96 orifice plates etc.；The front end of loading pipe is embedded in engraves
In emptying aperture 11.The one end of piston-in-sleeve 2 is located in external sleeve pipe 1, and with the interference fit of external sleeve pipe 1, the other end extends to external
Outside sleeve pipe 1；The extension of piston-in-sleeve 2 highly consistent (position in external sleeve pipe 1 is identical) in all loading pipes.External set
The bottom of pipe 1 is provided with check valve sheet 5, and the lower section of check valve sheet 5 is the accommodation space for treating loading liquid 6 for storage.External sleeve pipe 1
Lower end is sealed by pullover base 4.
Said apparatus can pass through conventional plate and all piston-in-sleeves 2 are pressed, it is also possible to arrange supporting pressing
Pressing plate 8.
The device course of work is following (by taking 96 orifice plates as an example)：
Outrigger 10 is placed in into the top of 96 orifice plate 9, external sleeve pipe 1 is embedded in hollow hole 11 and is fixed, then put pressing plate 8
On external sleeve pipe 1, the pullover base 4 of often pipe is removed, then alignment loading hole firmly presses pressing plate 8, piston-in-sleeve 2
Push, open pipe internal check valve piece 5, treat that loading liquid injects in loading hole simultaneously.
Situation in prevent the inwhole hand-holes of individual fluid occurs, and can also manually press do not use up liquid
Piston-in-sleeve 2, it is ensured that in stand-by liquid whole hand-hole.
