Abstract
The utility model relates to a kind of bacterium solutions to be coated with ball, multiple cynapse heads including nucleome He the outer surface for being distributed in the nucleome, each cynapse head includes base portion and the spreader portion that connect with the base portion, and one end far from the nucleome of the different spreader portions is on same spherical surface.Suitable bacterium solution coating ball need to only be added when bacterium solution is coated with for the utility model, with hand jog plate culture dish, it is allowed arbitrarily to roll on plate, due to there is cynapse head, so being easy to that bacterium solution is made to be dispersed in planar surface during scrolling, it is advantageous to single colonie generation.
Description
Technical field
The utility model relates to microculture fields more particularly to a kind of bacterium solution to be coated with ball.
Background technique
Clone is the highly important technology of molecular biology field.Most commonly used in laboratory is exactly by Exogenous DNA transfered
Bacterium (Escherichia coli) in vivo, then cultivates bacterium colony on LB culture medium, is proliferated DNA in bacterial body.In the process, I
Generally require picking single colonie and identified whether in Exogenous DNA transfered Escherichia coli body.In order to obtain single colonie, Wo Menxu
Want bacterium solution spreader that bacterium solution is equably coated in plating medium surface, purpose is exactly that bacterium is allowed to disperse to grow as far as possible, in order to
Our subsequent picking single colonies.Traditional bacterium solution spreader is asked as follows as shown in Figure 1, would generally be brought using this spreader
Topic: 1. since this spreader and plating medium surface contact surface are larger, easily cause during coating thin
Bacterium flocks together growth, is not easy picking single colonie.2. we must frequently replace painting when coating contains the bacterium solution of different exogenous DNAs
Cloth device, to ensure to contain only a kind of bacterium solution on each plate.Therefore we need many spreaders in the process, and such one
Come, not only can excessively occupy superclean bench operating space, and will increase the workload of subsequent spreader cleaning and sterilizing.
Utility model content
The purpose of this utility model is to provide a kind of bacterium solution coating ball for above-mentioned status.
The technical solution adopted in the utility model: a kind of bacterium solution is coated with ball, including nucleome and is distributed in the nucleome
Outer surface multiple cynapse heads, each cynapse head includes base portion and the spreader portion that connect with the base portion, different
One end far from the nucleome of the spreader portion is on same spherical surface.
The effect of the utility model is: suitable bacterium solution coating ball need to only be added in bacterium solution coating, with hand jog plate
Culture dish allows it arbitrarily to roll on plate, due to there is cynapse head, so being easy to be dispersed in bacterium solution during scrolling flat
Plate surface is advantageous to single colonie generation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that a kind of bacterium solution of the utility model is coated with ball；
Fig. 2 is the side view of cynapse head in Fig. 1；
Fig. 3 is a kind of side view of the cynapse head in preferred embodiment；

Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
Such as FIG. 1 to FIG. 2, a kind of bacterium solution provided by the utility model is coated with ball, including nucleome 1 and is distributed in nucleome 1
Outer surface cynapse head 2.Cynapse head 2 includes base portion 21 and the spreader portion 22 connecting with base portion 21, the smearing of all cynapse heads 2
The top in portion 22 is on same spherical surface.
Along the radial direction arrangement of nucleome 1, base portion 21 has the bottom edge 210 for being connected to 1 surface of nucleome and the bottom of from base portion 21
The outer peripheral surface 211 that end margin 210 is radially extended along nucleome 1.And the cross section of outer peripheral surface 211 is from one end of opposite nucleome 1 to another
One end is gradually reduced.
Preferably, nucleome 1 is sphere, and bottom edge 210 is circle.
Specifically, as shown in figure 3, in a kind of preferred embodiment, base portion 21A has from bottom margin 210A along nucleome
1 extends radially to the outer peripheral surface 211A of spreader portion 22A, i.e. base portion 21A is conical butt.
As shown in Figures 4 and 5, in another embodiment, base portion 21B has radial along nucleome 1 from bottom margin 210B
Extend to spreader portion 22B, outer peripheral surface 211B in inner sunken face.
As shown in figure 5, base portion 21C, which has from bottom margin 210C along 1 radial direction of nucleome, to be prolonged in other two kinds of embodiments
Extend to spreader portion 22C, outer peripheral surface 211C in convex outward.
It should be noted that spreader portion 22A, 22B, 22C are the circle that top is spherical surface in above two embodiment
Cylinder.
Ball is coated with using the bacterium solution of the utility model, suitable bacterium solution coating ball need to only be added in bacterium solution coating, use hand
Jog plate culture dish, allows it arbitrarily to roll on plate, due to there is cynapse head 2, so being easy to make bacterium during scrolling
Liquid is dispersed in planar surface, is advantageous to single colonie generation.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
