Description

A kind of bispecific monoclonal antibody that detects simultaneously Provado and parathion-methyl
(1) technical field
The present invention relates to be applied to detect simultaneously Provado and parathion-methyl bispecific monoclonal antibody and preparation method, belong to biological technical field.Be exclusively used in Provado in agricultural-food and agriculture production environment, residual sensitivity, the rapid detection of parathion-methyl, be specially adapted to batch samples and detect.
(2) background technology
Provado (imidacloprid, 1-(6-chloro-3-pyridylmethyl)-N-nitro-2-tetrahydroglyoxaline imines) and parathion-methyl (Parathion-methyl, O, O-dimethyl-O-(4-nitrophenyl) thiophosphatephosphorothioate) be the sterilant that is widely used in agriculture production, Provado belongs to the moderate toxicity novel nicotinamide insecticide, and parathion-methyl belongs to high malicious organophosphate insecticides.What at present, the residue detection in agricultural-food adopted to these two kinds of agricultural chemicals is vapor-phase chromatography (GC) and high performance liquid chromatography (HPLC); These two kinds of pesticide residue immune analysis methods also there is relevant report, but simultaneously has not yet to see report for immune many method for detecting residue of these two kinds of agricultural chemicals.
The pesticide multi-residues immuno analytical method mainly contains following three kinds: 1. with on multiple hapten conjugation to a carrier proteins, immune animal obtains antiserum(antisera) and carries out the pesticide multi-residues analysis; 2. extract the public structure of a series of agricultural chemicals, design universal hapten, immune animal obtains monoclonal antibody and is used for the pesticide multi-residues analysis; 3. bi-specific antibody method.First method makes it be subject to certain limitation on producing because being merely able to obtain polyclonal antibody; The prepared monoclonal antibody of second method is merely able to identify a class agricultural chemicals, can not detect simultaneously for different types of agricultural chemicals; And bi-specific antibody has solved this problem well, and bi-specific antibody has two different antigen binding sites because of it, and reaches the purpose that detects simultaneously the different sorts agricultural chemicals.
The preparation bi-specific antibody mainly contains following three kinds of methods: chemical crosslink technique, hybrid-hybridoma technique and genetic engineering antibody technology.The present invention utilizes parathion-methyl hybridoma and the technology that the BALB/C mice splenocyte that is subjected to the Provado immunogen immune merges, and prepares the secretion trisome hybridoma of anti-Provado-parathion-methyl monoclonal antibody simultaneously.
(3) summary of the invention
Technical problem the purpose of this invention is to provide a kind of can be used for detecting simultaneously parathion-methyl and the residual bispecific monoclonal antibody of imidacloprid pesticide and preparation method thereof.Prepare by the hybridoma that will secrete anti-parathion-methyl monoclonal antibody and the strategy that the BALB/C mice splenocyte that is subjected to the Provado immunogen immune merges the trisome hybridoma that to secrete anti-parathion-methyl-Provado bispecific antibody.
Technical scheme
1. anti-parathion-methyl and Provado bispecific monoclonal antibody, produced by trisome hybridoma cell strain FQ-D6, is the IgG2b-IgG1 type, and light chain of antibody is the kappa chain.
2. the preparation method of anti-parathion-methyl and Provado bispecific monoclonal antibody comprises:
(1) the HGPRT deficient hybridoma cell strain screening of the anti-parathion-methyl monoclonal antibody of secretion
The hybridoma cell strain of the anti-parathion-methyl antibody of secretion is placed in the 5ug/ml8-AG substratum and cultivates, improve gradually 8-AG concentration in substratum in culturing process, cell strain can be adapted in the substratum of the 8-AG of 50ug/ml grow; Utilize afterwards HAT selective d MEM substratum to screen, whether survive the enzyme in identification of cell whether to lack by cell, clone under deletion condition and enlarged culturing, and cell cryopreservation is standby.
(2) be subjected to the preparation of Provado immunogen immune BALB/C mice splenocyte
Exempted from by Provado immunogen 5, serum titer reached 1: 32000 above BALB/C mice booster immunization after 3 days, and eye socket is got blood and prepared serum, the positive control during as the trisome filtering hybridoma; Draw the neck dislocation to put to death the mouse after bloodletting, and be in 75% alcohol body surface sterilization 10 minutes, move into subsequently in Bechtop, be positioned in sterile petri dish, left abdomen up; Utilize aseptic operation tweezer and eye scissors to take out mouse spleen, wash gently with the DMEM basic medium, peel off as far as possible spleen fat and reticular tissue on every side; Spleen is placed in 120 purpose nylon filter bag, and puts into the culture dish that another fills the DMEM basic culture solution; Spleen in nylon filter bag is punctured and constantly extruding, splenocyte is discharged in the DMEM basic culture solution fully; Splenocyte suspension is transferred in the 50ml centrifuge tube, and centrifugal 10 molecules of 1000rpm are abandoned supernatant, will precipitate to wash once with about 30mlDMEM nutrient solution to suspend afterwards again, and are standby
(3) cytogamy
The HGPRT deficient hybridoma cell strain of splenocyte and the good anti-parathion-methyl antibody of secretion of growth conditions is prepared the trisome hybridoma by hybrid-hybridoma technique.And in 37 ℃, volume ratio 5% CO2gas incubator is cultivated, and detects by non-competing ELISA afterwards until 7 days and merges hole supernatant screening hybridoma.
