| 1 | Preparation of an anti-diethylstilbestrol monoclonal antibody and development of an indirect competitive ELISA to detect diethylstilbestrol in biological samples显示文摘Based on the preparation of an anti-diethylstilbestrol(DES) monoclonal antibody,a simple and convenient indirect competitive enzyme-linked immunosorbent assay(ELISA) method for DES detection has been developed.The monoclonal antibody demonstrated high sensitivity to DES with an IC50 value of 275 pg mL-1 and detection limit(LOD) of 90 pg mL-1.The specificity of the assay was studied by measuring cross-reactivity of the antibody with structurally related compounds of ethinyl estradiol(<7%),estrone(<0.1%),estriol(<0.1%),and diethylstilbestrol benzoate(<0.1%).Chicken,fish,shrimp,urine and bile spiked with different concentration of DES were detected by the developed method,and the recovery rates were greater than 79.5%.Intra-and inter-assay variations were about 6%.This method exhibited high stability with a coefficient of variation less than 10% in buffer and in real samples.The LODs in fish/shrimp,liver,feed and urine spiked with DES were 600,600,4800 and 600 pg mL-1,respectively.These results confirmed that the antibody to DES was successfully produced and could be used to establish ELISA methods for DES detection in food producing animals. | LI WeiHua MENG Meng HE FangYang WAN YuPing XUE HuYin LIU Wei YIN WeiWei XU Jing FENG CaiWei WANG ShanLiang LU Xiao LIU JinTing XI RiMo | 2011 | Chinese Science Bulletin2011，56，8： | 4 |

| 3 | Preparation of a Salmonella LAMP Detection Kit显示文摘[Objectives] This study was conducted to establish a method for rapid detection of Salmonella at the grassroots level, and a corresponding product was developed. [Methods] By analyzing the invA gene of Salmonella, two pairs of efficient, rapid and specific amplification primers were designed and screened for the six conserved domains of the gene, and the LAMP detection kit for Salmonella based on this method was produced. [Results] The method is simple, sensitive, rapid and specific. The minimum detection concentration is 10~2-10~3 CFU/ml. [Conclusions] It can be used in the self-inspection of food production enterprises and the on-site sampling inspection and rapid detection of large quantities of samples by grassroots food safety inspection and supervision departments. | Yuping WAN Xiaosheng WU Yu ZHANG Meihong DU Zhaoqin WANG Caiwei FENG Zhengmiao ZHAO Fangyang HE | 2019 | Agricultural Biotechnology2019，8，6： | 0 |
