    1. incubations were carried out for I h at RT and each incubation was followed by three washings with PBS containing 0.1% Tween-20 (PBST). Post-blocking, the membranes were incubated with 1:1000 dilution ofMA-813 ascites (for detection ofr-bmZP1), MA-451 ascites (for detection of r-dZP3) or rabbit polyclonal anti-r-rG antibodies (for detection of r-rG), followed by an incubation with 1:5000 dilution of goat anti-mouse or goat anti-rabbit immunoglobulins conjugated to horseradish peroxidase (HRPO) (Pierce) respectively. The blots were developed with 0.6% (w/v) 4-chloro-1-naphthol in 50 mM PBS containing 25% methanol and 0.06% H202• The reaction was stopped by extensive washing with double distilled water
    2. The cells (2 - 4 x 1 06) transfected with plasmid DNA were resuspended in minimum volume of 2X sample buffer (0.0625 M Tris, pH 6.8, 2% SDS, 10% glycerol, 5% P-mercaptoethanol, and 0.001% bromophenol blue). The samples were boiled for 10 min and resolved on a 0.1% SDS-1 0% PAGE (Laemmli, 1970). The expression of recombinant proteins was analyzed by Western Blot. The proteins were electrophoretically transferred to 0.45 J.lm nitrocellulose membrane 0/N at a constant current of 30 rnA (milliampere) in Tris-Giycine buffer (25 mM of Tris-HCl and 200 mM glycine) containing 20% methanol (Towbin et al., 1979). Post-transfer, the membranes were washed once with PBS and non-specific sites were blocked with 3% BSA in PBS for 90 min at RT. All the subsequent
