1, The invention discloses furazolidone metabolite hapten and antigen as well as a preparation method and application thereof.

2, Objective To study the preparation and characterization of hapten and artificial antigen of dicyclohexyl phthalate.

3, Ratios of hapten intergraded with BSA and OVA were 21:1 and 11:1, respectively.

4, The sulfamethazine hapten is a compound and the structural formula is shown as formula I.

5, Then, antigen was prepared by conjugation of hapten with carrier protein by carbodiimide(EDPC) method and was identified by UV spectroscopy and SDS-PAGE.

6, The hapten design and synthesis are the key steps for the development immunochemical method of pesiticide residue.

7, Hapten 2,4-D was covalently attached to bovine serum albumin (BSA) and ovalbumin (OVA) using the modified active ester method and the mixed-anhydride method, respectively.

8, Bisphenol A hapten (BPAH) was prepared by diazotization ,[http:///hapten.html] and then coupled with carrier protein bovine serum albumin (BSA) to prepare complete antigen BPAH-BSA.

9, The invention discloses a melamine hapten, a melamine antigen and a preparation method and applications thereof.

10, The swap of the Hawks for the hostages was scheduled to hapten on Thursday, November 21, 1985.

11, In this study the efficacy of adsorbents as antiendotoxin agents in a hapten induced rat model of colitis is investigated.

12, Conclusions: The experiments demonstrated that very potent effects could be achieved through the pro - transition - state hapten strategy.

13, Results According to carbodiimide method, antigens of OA-BSA and OA-OVA are successfully prepared from minute amount hapten of OA.

14, Aim: To study the method for treating mouse T lymphoma with hapten modified tumor vaccine.

15, Conclusion It was suggested that DCAC may not play a role of hapten during the onset of medicamentosa-like dermatitis caused by TCE.

16, First, T-2 toxin reacted with succinic anhydride in steam-bath to synthesize T-2 hemisuccinate(T-2HS). Thin layer chromatography analysis showed that the objective hapten was obtained successfully.

17, The horseradish peroxidase(HRP) tagged antibody was prepared by means of modified NaIO 4 method and the HRP tagged hapten was prepared by means of mixed anhydride method.

18, The development of enzyme immunoassays for the determination of pyrethroid residues were reviewed, including hapten design, antibody preparation, and immunoassay establishment and applications.

19, During contact, a small molecule from the plant, called a hapten, binds to carrier protein in the host.

20, Antibody combining sites in an antigenic determinant of cephalosporins were detected by enzyme linked immunosorbent assay (ELISA), hapten inhibition and passive cutaneous anaphylaxis(PCA).

21, The preparation method in the invention features convenience and feasibility, lower cost and higher yield of hapten.

22, The results showed that UV absorbance spectrum of artificial antigen of GA-BSA changed compared with carrier BSA and hapten GA.

23, The invention discloses a method for preparing cyanide-urea triamide hapten, artificial antigen and antibody as well as application thereof.

24, The quality of an enzyme immunoassays depends very much on the purity of the antigen or hapten used for conjugation, the specificity of the antibody and the choice of a suitable enzyme label.
