分别采用辣根过氧化物酶标记的羊抗兔抗体 (GAR -HRP)和碱性磷酸酯酶标记的羊抗兔抗体(GAR -AP) ,对甘薯羽状斑驳病毒 (SPFMV)、甘薯潜隐病毒 (SPLV)、甘薯轻斑驳病毒 (SPMMV)及甘薯褪绿病毒(SPCFV)进行NCM -ELISA检测 ,结果表明 ,采用GAR -HRP进行NCM -ELISA检测对于SPFMV、SPLV、SPM MV、SPCFV同样有效 ,且特异性高 ,重现性好 ,在某些方面优于GAR -AP。对于国内危害甘薯的SPFMV、SPLV等主要病毒 ,采用GAR -HRP进行ELISA检测更加经济有效 ,是切实可行的 Horseradish peroxidase-labeled goat anti-rabbit antibody (GAR-HRP) and alkaline phosphatase-labeled goat anti-rabbit antibody (GAR-AP) NCM-ELISA was used to detect SPMV, SPLV, SPMMV and SPCFV. The results showed that NCM-ELISA with GAR-HRP was also effective for SPFMV, SPLV, SPM MV and SPCFV. High specificity, good reproducibility and in some respects better than GAR-AP. For the domestic endangering sweet potato SPFMV, SPLV and other major viruses, the use of GAR-HRP ELISA test more cost-effective, is feasible
