  "abstract": "Bothrops marajoensis is a Brazilian pit viper whose venom remains poorly characterized compared with those of other medically important Bothrops species. In the present study, we performed a comparative biochemical characterization of B. marajoensis venom with six additional Bothrops venoms (B. alternatus, B. atrox, B. jararaca, B. jararacussu, B. moojeni, and B. neuwiedi). Venoms were analyzed by reversed-phase chromatography, electrophoresis, immunorecognition by commercial bothropic antivenom, phosphodiesterase activity, and their effects on the viability of differentiated C2C12 myotubes. Chromatographic and electrophoretic analyses revealed a largely conserved overall venom composition among species, with qualitative differences, although quantitative differences in protein relative abundance were evident. Bothropic antivenom recognized all venoms, indicating broad antigenic cross-reactivity despite venom variation. B. marajoensis exhibited intermediate phosphodiesterase (PDE) activity relative to other species evaluated, confirming functional variability among Bothrops venoms. In the cell viability assay, B. marajoensis displayed comparatively low apparent cytotoxicity toward differentiated C2C12 myotubes, maintaining higher cell viability than highly myotoxic venoms such as those of B. jararacussu and B. moojeni. These findings expand the biochemical characterization of B. marajoensis venom and demonstrate that, although venoms share the conserved toxin repertoire typical for Bothrops genus, quantitative differences influence its biological activities, preserving broad recognition by bothropic antivenom.",
