Detection of specific antibody IgM of Lyme disease by ELISA using recombinant outer surface protein C of borrelia burgdorferi / 临床检验杂志

ABSTRACT

Objective To detect specific IgM of Lyme disease indirect ELISA using recombinant outer surface protein C(OpsC)of Borrelia burgdorferi in vitro was established. Methods Coated concentration of recombinant OspC and dilution multiple of serum anol concentration of enzyme secondary antibody were determined by block,and degree of percision.specificity interference and interruption test were performed. Results Best concentration of OspC was 150 μg/L.within-run CV was 6.3% between-run CV was 11.8%.Confimred 33 Lyme patients in clinic and 57 controls were examined meanwhile by this method and import ELISA kit,coincidena rate was 97.8%.Conclusion This ELISA using recombinant OspC was a good method for early diagnostic of Lyme disease.
