Caspase-3 expression in tumour cell lines treatedwith PSK. AGS and B9 tumour cell lines were treated with 50 ÎĽg/ml of PSK and expression was analysed by flow cytometry using FITC conjugated monoclonal anti-active-caspase-3 antibody. Data indicate the percentage of cells positive for presence of active-caspase-3. PSK produced increased caspase-3 expression in AGS but not in B9 tumour cell lines. Results are representative of three experiments.
