Approximately 1g each of banana leaf sample collected in survey was ground separately (using a sterile mortar and pestle) in 10ml phosphate buffered saline-Tween (PBS-T) grinding buffer (0.01 M sodium phosphate; 15 mM sodium chloride, pH 7.4 containing 0.05 % Tween 20) containing 1 % w/v sodium sulfite and 2 % polyvinyl pyrrolidone) and loaded into their corresponding plates at 100 μ l/well and incubated as earlier described. Trapped BSV antigens were detected using a 1:4000 dilution of polyclonal antibody/goat anti- mouse alkaline phosphatase conjugate in PBS-T and monoclonal antibody for BSV .
