Heat shock protein70 associated with lymphatic filariasis (LF) has been identified from a cattle filarial parasite Setaria digitata. A heat shock protein was detected in different life stages of Setaria digitata when exposed to an elevated temperature of 44°C. A combination of ATP-agarose column chromatography and electro-elution was used for its purification from adult female extract. On closer examination, it migrated as a single band at 62 kDa on 10% SDS-PAGE. These observations suggest a plausible biological connection of ScHSP70 with the disease and its strong immunogenic nature. ScHSP70 showed antigenic cross-reactivity with IgG class of antibody in different categories of filarial sera. However, when IgG subclasses were tested, IgG4 showed high specificity and sensitivity with symptomatic microfilaraemic sera.
