Resumo

The ability to reversibly bind carbohydrates is an incredible property from lectins. Such characteristic has led these molecules to be employed in several applications involving medical research and biotechnology. Generally, these proteins follow several steps towards purification. Here, the synthesis, physical characterization, and use of levan-coated magnetite nanoparticles (MNPs-levan) for lectin isolation is described. Canavalia ensiformis and Cratylia mollis were used as sources of Concanavalin A and Cramoll, respectively, that were purified by using MNPs-levan. Mass spectrometry, SDS-PAGE, and hemagglutinating activity were employed to assess the efficiency of the process. Moreover, by using mass spectrometry approaches, a novel lectin, similar to Canavalin, was also identified for C. mollis, corroborating the advantages of using nanoparticles over microparticles. MNPs-levan could also be recycled, making this a low-cost, scalable process that can be efficiently employed over crude samples.
