Alcoholic solution；
The albumen that immune complex can be captured is the albumen that can be specifically bound with immune complex, including but not limited to
Such as C1Q, CIF albumen, anti-C_3 antibody；In following embodiment, can capture immune complex albumen it is specifically used be
C1qRecombinantProtein, article No. are " NOVUSH00000712-p01 "；
The substance of capture arsenic is the anti-AsmAb of mouse that article No. is " Guangzhou Ran Ke companies RK15728 ", in following implementation
With arsenic specific binding substance, with arsenic have the substance, secondary antibody, anti-arsenic antibody of affinity be capture arsenic substance；
The antibody that can be specifically bound with human serum albumins is rabbit anti-human serum albumin antibodies, is commercially available.
Dilution multiple proportions is w/v below.
Method one：ELISA method detection arsenic chelating type immune complex, is as follows：
1) albumen that can capture immune complex is coated on solid phase carrier：C1Q is diluted with dilution buffer
Albumen is added to 2500-20000 times in elisa plate micropore, and 4 DEG C of 16-18 hour overnight or 37 DEG C of water-baths 1-3 hours store
Refrigerator；
2) it closes：Dilution buffer is removed, washing buffer is used in combination to be washed, is waited after the completion of washing, adds confining liquid, 37
It DEG C places 1 hour, removes confining liquid, washing buffer is used in combination to be washed, after the completion of washing, elisa plate is placed 1 small in 37 DEG C
When；
3) add sample to be tested, and incubate：It is sampled from the circulatory system, makees sample to be tested；With the arsenic chelating type of known content
Immune complex makees standard items；10-40 times is diluted with dilution buffer, is added in micropore, 37 DEG C act on 1-2 hours；
4) substance of capture arsenic is added, and incubates：Sample to be tested is removed, washing buffer is used in combination to be washed, it is to be washed
After the completion of washing, addition is diluted with dilution buffer to be had the substance of affinity with arsenic or can react to form antigen antibody complex with arsenic
Anti- arsenic antibody be diluted to 30000-250000 times, 37 DEG C act on 1-2 hours, it is made to be reacted with the arsenic on immune complex；
5) enzyme conjugates incubates：Anti- arsenic antibody is removed, washing buffer is used in combination to be washed, is waited after the completion of washing, is added
With the diluted HRP enzyme labelled antibodies of dilution buffer, 37 DEG C act on 1-2 hours, make itself and anti-arsenic antibody response；
6) substrate incubates：Enzyme labelled antibody is removed, washing buffer is used in combination to be washed, is waited after the completion of washing, substrate is added,
37 DEG C are protected from light effect 30 minutes；
7) reaction is terminated：Terminate liquid is added dropwise to each micropore；
8) it is 405nm to take wavelength, and elisa plate is placed in microplate reader to the OD for reading sample to be tested group and standard items respectively
Value draws standard curve, acquires the content of sample to be tested.
In this method, when step 8) detects, microplate reader can not be used, qualitative inspection is directly carried out by the situation that develops the color yet.
This method utilizes enzyme linked immunosorbent assay (ELISA) (ELISA) principle, can be compound by the nospecific immunity in serum
Object extracts, and weight arsenic is partly chelated on the immune complex extracted, and the arsenic on this partial immunity compound can be with
It is captured by the substance for having affinity with arsenic or the specific antibody that the anti-arsenic to form antigen antibody complex can be reacted with arsenic, it
Can (antibody nonrecognition coating egg be captured by the antibody that the enzymes such as horseradish peroxidase, alkaline phosphatase mark again afterwards
In vain), the antibody in capture reads OD values under the action of color developing agent and terminate liquid under instrument, and exempts from without containing chelating arsenic
Epidemic disease compound will not then be captured by the specific antibody of anti-arsenic, will not be with the enzymes such as horseradish peroxidase, alkaline phosphatase
The antibody of label is captured, and arsenic (negative control group result is feminine gender) is not contained in agents useful for same yet, thus when read
When OD value results are shown as the positive, you can prove the arsenic for detecting to chelate on CIC ELISA.
Method two：ELISA method+AAS methods detect arsenic chelating type immune complex, are as follows：
1) albumen that can capture immune complex is coated on solid phase carrier：Coating protein is diluted with dilution buffer
It to 5000-15000 times, is added in elisa plate micropore, 4 DEG C of 16-18 hour overnight or 37 DEG C of water-baths 1-3 hours, storage refrigerator；
2) it closes：Dilution buffer is removed, washing buffer is used in combination to be washed, is waited after the completion of washing, adds confining liquid, 37
It DEG C places 1 hour, removes confining liquid, washing buffer is used in combination to be washed, after the completion of washing, elisa plate is placed 1 small in 37 DEG C
When；
3) add sample to be tested, and incubate：It is sampled from the circulatory system, makees sample to be tested；With the arsenic chelating type of known content
Immune complex makees standard items；10-40 times is diluted with dilution buffer, is added in micropore, 37 DEG C act on 1-2 hours；
4) it elutes：Sample to be tested is removed, washing buffer is used in combination to be washed, is waited after the completion of washing, eluent is added, in
It is acted on 1-2 hours at 37 DEG C；
5) it detects：It samples from ELISA micropores, is chelated in the arsenic on immune complex in Atomic Absorption Spectrometer detection,
Read respective value.
This method further combines atomic absorption spectrum (AAS) principle on the basis of enzyme linked immunological principle, utilizes original
Sub- absorption spectrometer detection chelating is in the arsenic on CIC ELISA, due to only containing immune complex in solution, and it is used
Without arsenic (negative control group result is feminine gender) in reagent, result will not be shone at interference, thus when read result is shown
For the positive when, you can prove the arsenic for detecting to chelate on CIC ELISA.
The method of the present invention scope of application is wider, can be cost-effective, and increases the differential water pressures inside and outside bag filter, improves
It dialyses rate, can shorten manufacturing cycle, also the wastes such as ion in waste liquid are handled, has the characteristics that energy conservation and environmental protection, keeps away
Exempt to cause chemical contamination, therefore the present invention has the larger market competitiveness.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
Understanding without departing from the principles and spirit of the present invention can carry out these embodiments a variety of variations, modification, replace
And modification, the scope of the present invention is defined by the appended.
