Microinjection ware is exactly the important item used in micromanipulation.It needs sperm and egg mother cell being respectively put into ware when operation
In, for being used when injection, and entire injection process will also be completed in ware.
Utility model content
The purpose of this utility model is to provide a kind of monosperm microinjection ware, and cost is relatively low, easy to make, and is convenient for
Operation.
To achieve the above object, the utility model provides a kind of monosperm microinjection ware, including injection ware ontology, described
The surface of injection ware ontology (1) has the drop positioning region that multiple transverse and longitudinals are staggered；Wherein, it is located at most upper row and most descends row's
The drop positioning region has to place the HEPES drops of egg mother cell；Positioned at an intermediate row and positioned at intermediate and left lateral position
The drop positioning region set has PVP drops, has positioned at the drop positioning region of intermediate row's right positions to put
Set the HEPES drops of sperm.
Preferably, the drop positioning region is specially nine, and is in three rows, three column distribution.
Preferably, the drop positioning region is specially counterbore, groove or the plane with telltale mark.
Preferably, all the drop positioning region is specifically rounded.
Preferably, further include the mineral being covered on the HEPES drops and PVP drops for having placed egg mother cell and sperm
Oil reservoir.
Preferably, the injection ware ontology is specifically rounded.
Relative to above-mentioned background technology, the utility model provides a kind of monosperm microinjection ware, including injection ware ontology,
The surface of injection ware ontology has the drop positioning region that multiple transverse and longitudinals are staggered；Wherein, it is located at most upper row and most descends the institute of row
Stating drop positioning region has to place the HEPES drops of egg mother cell；Positioned at an intermediate row and positioned at intermediate and leftward position
The drop positioning region there is PVP drops, have positioned at the drop positioning region of intermediate row's right positions to place
The HEPES drops of sperm.
It is more convenient when in use so set, the layout of drop is concise, immobilization of spermatozoa most intermediate, sperm and
Around egg mother cell is centered around；And the cost of monosperm microinjection ware is relatively low, and it is easy to make, it is easy to operation.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is the embodiments of the present invention, for those of ordinary skill in the art, without creative efforts, also
Other attached drawings can be obtained according to the attached drawing of offer.
The schematic diagram for the monosperm microinjection ware that Fig. 1 is provided by the utility model embodiment.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
In order to make those skilled in the art more fully understand the utility model, below in conjunction with the accompanying drawings and specifically
The utility model is described in further detail for embodiment.
Referring to FIG. 1, the schematic diagram for the monosperm microinjection ware that Fig. 1 is provided by the utility model embodiment.
A kind of monosperm microinjection ware provided by the utility model, including injection ware ontology 1, injection ware ontology 1 is usually
For circular transparent glass ware, specific size can be decided according to the actual requirements.
Multiple drop positioning regions are equipped on the surface of injection ware ontology 1, drop positioning region transverse and longitudinal is staggered；With specification
For attached drawing 1, drop positioning region is nine, is in three rows, three column distribution.Three drop positioning regions 14 of most upper row and most descend row's
Three drop positioning regions 15 have HEPES drops；For three drop positioning regions of an intermediate row, the drop on the left side positions
Portion 11 and intermediate drop positioning region 12 have PVP drops, and the drop positioning region 13 for being located at the right has HEPES drops.
Wherein, PVP, that is, polyvinylpyrrolidone herein is a kind of macromolecular substances, can make Sperm vectors
Slow down, convenient for selection sperm.
HEPES is a kind of no CO2The buffer solution of dependence can maintain physiological ph in air.
In use, three drop positioning regions 14 of most upper row and three drop positioning regions 15 of row are most descended
It is put into egg mother cell in HEPES drops, for three drop positioning regions of an intermediate row, the drop for being located at the right positions
HEPES drops in portion 13 are put into sperm, and the PVP drops in the drop positioning region 11 on the left side and intermediate drop positioning region 12
In PVP drops be respectively used to cleaning injection needle and brake sperm use；The monosperm microinjection ware of such setting, structure
Simply, easy to make, and be easy to use.
Certainly, according to actual needs, the number of drop positioning region can be decided according to the actual requirements, and be not restricted to this
Nine described in text.
Can be specially counterbore, groove or the plane with telltale mark for drop positioning region.That is, injecting
The surface setting counterbore or groove of ware ontology 1, can effectively play the effect of positioning, facilitate and drip HEPES drops and PVP drops
Enter corresponding position；At the same time, with telltale mark plane be without injection ware ontology 1 surface setting counterbore or
The special shapes such as groove, but by draw in the prior art label etc. in the way of produce telltale mark, with facilitate by
HEPES drops position corresponding with the instillation of PVP drops.Certainly, according to actual needs, drop positioning region can also use existing skill
Other in art will not be described in great detail herein to realize the component of positioning.
Wherein, drop positioning region can be specific rounded.Namely counterbore and groove can be circle；It is also possible to make
Circular mark plays positioning action.Circular drop positioning region is easy to make, contributes to the life for reducing monosperm microinjection ware
Produce cost.
After corresponding HEPES drops and PVP drops are carried out, mineral oil layer is covered, then by monosperm microinjection
Ware is put into incubator and is balanced, and egg mother cell and sperm can be positioned in corresponding drop after balance is good and used.
Monosperm microinjection ware provided by the utility model is described in detail above.Tool used herein
Body example is expounded the principles of the present invention and embodiment, and the explanation of above example is only intended to help to understand
