作者报道反转录聚合酶链式反应（ＲＴ－ＰＣＲ），双单克隆抗体（ＭｃＡｂ）夹心法酶联免疫吸附试验（ＳａｎｄｗｉｃｈＥＬＩＳＡ）和间接免疫荧光技术（ＩＦＡ）三种方法对汉坦病毒７６～１１８株细胞培养物中病毒ＲＮＡ及抗原的检测情况，并比较了三种方法的敏感性．结果表明：ＲＴ－ＰＣＲ敏感性最高，种毒后２４ｈ内即可检出病毒ＲＮＡ；其次为夹心法ＥＬＩＳＡ，种毒后４８ｈ可检出冻融细胞上清内的病毒抗原；ＩＦＡ检出感染细胞内病毒抗原的最短时间为７２ｈ．作者对设计引物与提高ＲＴ－ＰＣＲ的敏感性进行了讨论。
The authors reported three methods of reverse transcription-polymerase chain reaction (RT-PCR), sandwich ELISA and Sanda ELISA (indirect immunofluorescence assay) 118 cell cultures of viral RNA and antigen detection, and compared the sensitivity of the three methods. The results showed that RT-PCR had the highest sensitivity and could detect the virus RNA within 24 hours after being infected with the virus. The second was sandwich ELISA, and the virus antigen in the supernatant of frozen-thaw cells could be detected 48 h after being infected. IFA detected the infected cells The shortest time for virus antigen is 72h. The authors discussed the design of primers and their sensitivity to improve RT-PCR.
