Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.In addition, institute in each embodiment of the utility model disclosed below
As long as the technical characteristic being related to does not form conflict each other, can is mutually combined.
The utility model provides a kind of Western blotting film 1, and the surface of Western blotting film 1 has with hydrophobic region
Multiple strip hydrophilic regions 12 at 11 intervals, the material of the strip hydrophilic region 12 are nitrocellulose, nylon or gather inclined fluorine
Ethene, so as to combining target antigen, the hydrophobic region 11 is usually organic hydrophobic polymer with silylation, also simultaneously
Siloxy or silicone hydroxyl may be carried, such as dimethyl silicone polymer or derivatives thereof;
The strip hydrophilic region 12 has one or more lands 13 along its length, has on the land 13
There is target antigen, the target antigen is used to be combined with the target protein of Western blotting;When the strip hydrophilic region 12 includes
During multiple lands 13, land 13 can be divided into test block and check plot, and test block is used to be combined with target protein, and compares
Area can be divided into positive control area, negative control area or conjugate check plot according to its function;Wherein, positive control area generally contains
There is the antigen that can be combined with other compositions in solution to be measured in addition to target antibody, for example, when using blood as solution to be measured,
The target antigen of positive control area can then use serum antibody, and positive control area colour developing proves that Western blotting film 1 does not go bad, and
Solution type to be measured is errorless;And negative control area can be coated with unlabelled secondary antibody so that negative control area at the standard conditions
It can not develop the color, if it develops the color, it was demonstrated that the abnormal conditions such as may have Western blotting film 1 rotten, it should change Western blotting film 1
And redeterminate;And the target antigen of conjugate check plot is IgG conjugates, IgM conjugates or IgA conjugates, due to IgG,
IgM and IgA is common immunoglobulin, and the presence of conjugate check plot may indicate that whether target antibody has successfully combined.
The width of the strip hydrophilic region 12 and hydrophobic region 11 is usually 1mm~5mm, is being easy to do Western blotting
While test, it is ensured that each strip hydrophilic region 12 is spaced completely, while effectively utilizes the space of Western blotting film 1.
For the ease of storing and using, the Western blotting film 1 can be along the direction of strip hydrophilic region around cylindric
Or cylindric support shaft 2 is around the spool structure for being made as a diameter of 2cm~6cm, as shown in Figure 5.
The preparation method of the Western blotting film 1 is roughly divided into two kinds:
The first:The combining target antigen on substrate film, it is described to form the quantity identical junction belt with target antigen
The material of substrate film is nitrocellulose, nylon or Kynoar;Hydrophobic region 11 is formed on substrate film with hydrophobic coating,
So that substrate film is divided into multiple strip hydrophilic regions 12, while by junction belt land 13 corresponding with junction belt so that every
Individual strip hydrophilic region 12 all has the quantity identical land 13 with target antigen;Hydrophobic coating needs are nontoxic, and
Less than 37 degree can dry, in order to avoid the activity of target antigen is influenceed, such as the hydrophobic coating in patent document CN201380057250.
Second:The parallel patch of multiple strip hydrophilic films is formed on hydrophobic film so that have on the hydrophobic film
With multiple strip hydrophilic films formed strip hydrophilic region 12, the strip hydrophilic region 12 with hydrophobic region 11 separately;
The hydrophobic film surface can be provided with the groove being engaged with strip hydrophilic film, to be combined simultaneously in strip hydrophilic film
It is fixed so that the surface where strip hydrophilic region 12 is less than the surface where hydrophobic region, can so be further ensured that strip
Reaction solution between hydrophilic region 12 will not interact mixing.
Above-mentioned Western blotting film 1 can be applied to immune-blotting method, so that indirect method carries out chemiluminescence detection as an example, tool
Body comprises the following steps:
S1. set above away from strip hydrophilic region 12 at 0.1mm~2mm corresponding with the quantity of strip hydrophilic region 12
Liquid-feeding tube, a variety of solution to be measured are made in solution to be measured by liquid-feeding tube with making an addition to the different surfaces of strip hydrophilic region 12
Target antibody and junction belt on target antigen be completely combined;Simultaneously so that the strip hydrophilic region 12 of liquid-feeding tube is with 1cm/s
~15cm/s speed does relatively reciprocating motion, and while motion, still can be slowly added solution to be measured in bar by liquid-feeding tube
The surface of shape hydrophilic region 12, to prevent liquid evaporation, to keep the liquid level on strip hydrophilic region 12 as the mm of 0.1mm~1;
In the case, it is computed, even if the solution to be measured remained in liquid-feeding tube is counted, the volume of required solution to be measured
Several tens of microliters is only needed to milliliter level;
S2. collector tube can be set in one end of each strip hydrophilic region 12, one end of collector tube is away from strip hydrophilic region 12
Top 0.1mm~2mm, other end connection vavuum pump, after completion of the reaction, vavuum pump aspirates strip hydrophilic region by collector tube
Unnecessary solution to be measured on 12;
S3. in a manner of same in S1-S2., the solution to be measured in former liquid-feeding tube is substituted with buffer solution, Western blotting is thin
The solution to be measured on the surface of film 1 is rinsed well;Because buffer solution is usually the lower-cost solution such as PBS, relative to solution to be measured,
More volume can be added;
S4. in a manner of same in S1-S2., the buffer solution in former liquid-feeding tube is substituted with two corresponding anti-solution so that secondary antibody is complete
Combined with target antibody;
S5. in a manner of same in S3., the two corresponding anti-solution in former liquid-feeding tube is substituted with buffer solution, by Western blotting film 1
The two corresponding anti-solution on surface is rinsed well;
S6. in a manner of same in S1-S2., the buffer solution in former liquid-feeding tube is substituted with chemiluminescence agent solution so that mark
The secondary antibody recorded a demerit lights;
S7. in a manner of same in S3., the chemiluminescence agent solution in former liquid-feeding tube is substituted with buffer solution, by Diagnosis of Sghistosomiasis
The chemiluminescence agent solution on the surface of mark film 1 is rinsed well;
S8. adaptive immune trace testing result.
