Abstract:
The soluble extracts of Gastrothylax crumenifer isolated from the rumen of buffalo (Bubalus bubalis) were fractionated on a Sephadex G-200 column. A total of eight major fractions (F1, F2, F3, F4, F5, F6, F7, and F8) were separated from the whole homogenate of G. crumenifer, and each of these fractions was tested for their antigenicity by ELISA against rabbit hyperimmune sera. It was observed that F1, F2, F3 and F4 were highly antigenic, F6 and F7 were moderately antigenic and F5 and F8 were poorly antigenic. The individual fractions analysed after SDS-PAGE and Western blotting indicated that the antigenic fractions of G. crumenifer are of low molecular weight, in the range of <14-50kDa, and predominant antigenic components which were evident in most of the Sephadex profiles were of Mr 15, 18, 19, 23-24 and 28-32kDa.
