From: Heparanase activity in alveolar and embryonal rhabdomyosarcoma: implications for tumor invasion
Heparanase activity in serum-free conditioned media of rhabdomyosarcoma cell lines. The enzymatic activity is expressed as nanograms of heparan sulphate (HS) removed per minute. The results represent the mean ± standard deviation of three independent experiments performed in duplicate. Platelet extract was used as positive control (PC, white bar); ARMS (black bars); ERMS (grey bars).
