摘  要:
对伪狂犬病病毒(PRV)、猪细小病毒(PPV)和流行性乙型脑炎病毒(JEV)检测基因芯片的制备及该芯片的检测技术进行了研究。选定靶基因最佳点样质量浓度为200 mg/L,用基因芯片点样仪将其点制在氨基化基片上,经干燥、水合、紫外线交联和洗涤后,成功制备了PRV-PPV-JEV检测基因芯片。以CY3荧光素标记的dCTP经PCR扩增制备探针,对芯片的质量进行了评价。结果表明,制备的芯片质量好,探针最佳使用质量浓度为3 000μg/L,芯片系统检测灵敏度可达3μg/L。该芯片可同时检测PRV、PPV和JEV,其灵敏度高、特异性强,芯片可重复使用,室温下至少可保存4个月。

摘  要:
PRV,PPV and JEV detection microarray have been prepared in this test.The microarray has been fabricated by spotting target genes on animated slide with the best concentration 200 mg/L of each target gene firstly,then the slide dried,hydrated,UV cross-linked and washed.Probes were labelled by PCR with CY3-dCTP to evaluate the qualification of the microarray.The best concentration of the probe was 3 000 μg/L,with the sensitivity of the microarray detection system of 3 μg/L.The results showed that PRV,PPV and JEV can be detected simultaneously by the microarray with high sensitivity and specificity.The microarray can be reutilized for at least 10 times and conserved for at least 4 months.
