ABSTRACT
Filarial antigen was isolated from hydrocoele fluid and fractionated on Ultrogel AcA 44. Six protein fractions (HFA C1 to HFA C6) were chromatographically separated from the column. Of the 4 antigenic fractions (HFA C1, HFA C2, HFA C3 and HFA C5), HFA C3 was a major reactive fraction with filarial serum immunoglobulin G. Analysis of HFA C3 by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) yielded 18 bands of Mr 18,000-160,000. Two fractions, HFA C3-7 and HFA C3-9 of Mr 48,000-55,000 and 32,000-39,000 obtained by gel elution, were antigenic in an enzyme-linked immunosorbent assay (ELISA). SDS-PAGE immunoblotting confirmed the ELISA by identifying 3 immunoreactive bands of Mr 51,000, 38,000 and 35,000. The diagnostic potential of HFA C3-7 and HFA C3-9 was compared in serodiagnosis of active infections and diseased states. HFA C3-9 showed greater sensitivity in detection of filarial specific IgM antibody in cases with microfilaraemia. Physicochemical characterization indicated the protein nature of HFA C3-9.
