Abstract
The invention discloses a kind of method that female phenol and bisphenol-A are detected based on double antibody sandwich method.Described method is：The electrochemical immunosensor of surface finish nano gold TGA hexestrol monoclonal antibody is prepared first, then using double antibody sandwich method to testing sample in female phenol or bisphenol-A detect, by the analysis and derivation of related data, you can obtain the concentration of female phenol or bisphenol-A.The detection of the method detection diethylstilbestrol that the present invention is provided is limited to 0.06ng/mL, and the range of linearity is 0.5~1000ng/mL；Detect that the detection of hexestrol is limited to 0.052ng/mL, the range of linearity is 0.5~1000ng/mL；Detect that the detection of dienestrol is limited to 0.047ng/mL, the range of linearity is 0.5~500ng/mL；Detect that the detection of bisphenol-A is limited to 0.037ng/mL, the range of linearity is 0.5~500ng/mL.Detection method of the present invention is quick, efficient, sensitivity is high, with very low test limit and the range of linearity wider.
Description
Technical field
The invention belongs to food safety detection and technical field of analytical chemistry, it is related to a kind of electricity based on double antibody sandwich method
Chemo-immunity detection method, specifically a kind of method that female phenol and bisphenol-A are detected based on double antibody sandwich method.
Background technology
Diethylstilbestrol (diethylstilbestrol, DES), hexestrol (hexestrol, HEX) and dienestrol
(dienestrol, DIEN) (structure is shown in formula 1) belongs to artificial synthesized estrogenic chemicalses (hereinafter referred to as female phenol), with promotion
Growth of animal, improve food conversion ratio and reduce Fatty synthesis etc. effect, be once widely used in the sixties in 20th century animal husbandry life
Produce.This kind of artificial hormone can disturb the hormonal balance of human normal by food chain, endanger human health, such as cause organism metabolism
The serious problem such as disorder, dysplasia, breast cancer and fetal anomaly, all prohibites in animal in the country such as China and America and Europe
Used in breeding process.
Bisphenol-A (bisphenol A, BPA) (structure is shown in formula 1) has just been widely used in since the sixties manufacturing plastics
(milk) bottle, the cup with sucking device of child, food and beverage (milk powder) tank inner side coating, from mineral water bottle, medicine equipment to food bag
Dress inside, there is its figure, can say it is ubiquitous.The structure and property of bisphenol-A seemingly, can cause endocrine with female phenols
Imbalance, in addition caused by cancer and metabolic disturbance obesity be recognized as it is associated.European Union thinks the feeding bottle meeting containing bisphenol-A
Sex premature is induced, from 2 days March in 2011, forbids baby bottles of the production containing bisphenol-A.
Mainly there are high performance liquid chromatography, liquid chromatograph mass spectrography currently used for the method for the detection of female phenol and bisphenol-A
Method, capillary electrophoresis etc..But these analysis methods need large-sized analytic instrument, detection time is long, high cost, therefore have must
Set up more efficient, quick, sensitive analysis test method.
Double antibody sandwich method is normally used for the analysis inspection of macromolecular antigen (such as protein, virus, tumor markers)
Survey, and micromolecular compound is due to small volume, generally cannot be in combination with two antibody, therefore micromolecular compound is typically difficult
Detected with double antibody sandwich method.Female phenol and bisphenol-A are all the difunctional linear molecule with symmetrical structure, from theory
On say can be with two antibody in combination with being basis that the present invention detects female phenol and bisphenol-A using double antibody sandwich method.
The content of the invention
The invention provides a kind of female phenol of detection based on double antibody sandwich method and the method for bisphenol-A, described method is fast
Speed, efficiently, sensitivity it is high, with very low test limit (0.037~0.060ng/mL) and the range of linearity wider (0.5~
1000ng/mL or 0.5~500ng/mL).
The technical solution adopted in the present invention comprises the following steps：
1) preparation of the electrochemical immunosensor of nm of gold-TGA-hexestrol monoclonal antibody modification：First will
