A fluorescence immunochromatographic strip was developed in this study for natamycin detection in food. The results showed that the best amount of labeled antibody was 10 μg, for every 50 μl of fluorescent microspheres with a 2.5%(w/v) concentration. This labeled antibody was diluted for 10 times, and the diluted solution was dispensed into conjugate pad at the amount of 3 μl/cm. The concentrations of natamycin labeled BSA for test line and goat anti-mouse IgG for control line were 2.0 and 1 mg/ml, respectively, which performed best. With the best conditions, the limit of detection was 1 ng/ml, the linearity ranged from 2 to 100 ng/ml, the recovery was about 80% to 120%, and the CV was below 23%.

利用近红外光谱技术对四种蛋白酶(菠萝、碱性、木瓜和中性蛋白酶)的大豆分离蛋白水解样品进行测定,探索同一模型应用于不同酶的水解液抗氧化性测定的可行性。基于留一交叉验证方法,分析了采样密度和酶物质差异对全波长模型精度的影响,统计检验表明,采样密度与模型精度之间正相关,酶物质差异对单酶样本模型精度无显著影响,但对综合酶样本模型性能有显著影响。为了建立能够同时准确测定不同酶水解样品抗氧化性能力的综合酶样本预测模型,竞争性自适应重加权抽样(CARS)法用来对模型进行了优化,建模后,校正集R_(cv)和RMSECV分别为0.960 1和0.002 8,验证集的R_p和RMSEP为0.923 7和0.005 3,相对分析误差(RPD)为2.45,预测精度较好,说明建立针对不同酶的水解样品的同一模型是可行的。

Maize chlorotic mottle virus （MCMV） is a quarantine pest as approved by Chinese government： A rapid, sensitive and specific MCMV detection method using reverse transcription-loop-mediated isothermal amplification （RT-LAMP） was established in this study. Based on the sequence of MCMV coat protein coding gene, 3 sets of primers were designed and specificity test showed that the second set of primers was specific to MCMV, Similar sensitivities were observed on RT-LAMP and RT-PCR, except that RT-LAMP was quicker, and the reaction could be finished within 1 h. In addition, the presence or absence of the fluorescence under daylight allows naked easy detection of the amplification of MCMV genomic RNA using calcein. The RT-LAMP assay was applied successfully to detect MCMV in maize seeds, and the result by the addition of calcein was consistent with the result detected by the real time turbidimeter. The method is rapid, specific, sensitive without the need for complicated equipment, and is suitable for rapid field detection of MCMV.

通过热分解法制备了IrO2+SnO2/Sb2O3+SnO2/Ti、IrO2+SnO2/Ti、IrO2+Ta2O5/Sb2O3+SnO2/Ti电极,通过线性伏安、电化学阻抗、强化寿命测试等研究了钛基涂层电极在1mol.L-1硫酸溶液中的析氧性能。采用EDX、SEM等考察了电极的表面元素分布和电极强化寿命测试前后的表面形貌;并将上述电极作为阳极,以铅合金电极为阴极应用于电合成丁二酸体系,考察不同阳极的选用对电解结果的影响。结果表明,钛基涂层电极比传统Pb及其合金电极具有更低的析氧电位,在电合成丁二酸体系中,其槽电压可降低0.5～0.7V,节约直流电耗10%以上;同时电解产物丁二酸的电流效率高于95%。在3种钛基涂层电极的比较中发现,以SnO2替代活性层中的Ta2O5后,钛基IrO2-SnO2涂层电极仍具有较高的析氧活性,工作寿命可达1456d,虽然槽电压和电解电耗略高,但由于替代了活性层中的部分贵金属,IrO2+SnO2/Sb2O3+SnO2/Ti电极仍具有较高性价比,具有较好的应用前景。
