The western-blotting results indicated that the expressed proteins could be recognized by the PPV positive serum. These results showed that expressed proteins can be used in genetic engineering diagnostic antigen .

• 经Western-blotting证明pGEX-NS1-HN1重组蛋白可被感染猪细小病毒阳性血清所识别,然而pGEX-VP2-HN1重组蛋白可被猪细小病毒阳性血清所识别,表达蛋白可用于基因工程诊断抗原。
