Abstract:
Objective:To apply immuno-PCR for detection of anti-Sm antibodies.Methods: Immuno-PCR was established for anti-Sm antibodies in SLE sera using SaHIgG-DNA probe. The experimental conditions were optomized and methological identifieation indicated obvious in crease(×107 ) in sensitivity compared with that of ELISA. The positive rate of anti-Sm antibodies was 54.9% in SLE sera, and significantly higher than that of ELISA. Intra-and inter-CV were 2.3%～4.8% and 3.7%～6.9% respectively. Immuno-PCR was positively correlated with ELISA( p ＜0.001). Therefore, immuno-PCR for anti-Sm antibodies is specific,sensitive,reproducible and practical clinically.
