감자바이러스X(PVX)의 진단과 동정을 위하여 PVX를 순수분리 순화하여 항혈청을 제조하였다. PVX는 지표식물과 전자현미경으로 순수분리하여 도마도애서 증식한 개량된 방법으로 순화하었다. 순화된 PVX의 순화도는 0.59mg/ml이었으며, 이를 1-2ml씩 7일 간격으로 5회 토끼에 주사하였다. 마지막 주사후 10일에 채혈하여 항혈청을 분리하였다. 제조된 항혈청의 력가는 미량침강법에서 1/1024이었고. 한천내확산법에서도 판명한 반응을 관찰할 수 있었다.
Potato virus X was purified especially for the preparation of antisera for diagnosis and identification. Potato virus X was isolated Iron infected plants by means of indicator plants and identified in electron microscopy. Isolated PVX was multiplied in tomato plants and purified by a modified procedures. The purity of PVX was 0.59mg/m1. Purified PVX was injected into rabbits once a week for 5 weeks. Antiserum was collected 10 days after the last injection. Produced antiserum was determined 1/1024 titers by means of microprecipitin tests and showed sharp reactions in agar gel-diffusion tests.
