The efficacy of Moringa oleifera seed lectin (WSMoL) as a metal remover in water and the effects of metals on its hemagglutinating and antibacterial activities were determined. Aqueous metal solutions were incubated with WSMoL for 8 h at 4°C and the concentrations of metals were determined using atomic absorption spectroscopy. Hemagglutination and(More)
This study characterized the protein/peptide profile of venom isolated from the spider Lasiodora sp. (Mygalomorphae, Theraphosidae) found in northeastern Brazil and determined its antimicrobial activity, toxicity against human cells, and hemolytic activity. Protein concentration of the Lasiodora sp. venom was 4.53 ± 0.38 mg/mL. SDS-PAGE showed proteins with(More)
This work describes the isolation of a lectin (CasuL) from the leaf pinnulae of Calliandra surinamensis and the evaluation of its cytotoxic, antimicrobial and antibiofilm properties. Proteins from pinnulae extract were precipitated with ammonium sulphate (60% saturation) and submitted to Sephadex G-75 chromatography, which yielded isolated CasuL(More)
