Mariángela Vargas Arroyo

Mariángela Vargas is a part of the Technological Development team of the Industrial Division. Her researches focus on the improvement of antivenoms from the point of view of productivity, efficacy, safety, and stability. She has participated in the development and improvement of the PoliVal ICP antivenom, of liquid formulations of antivenoms stabilized with osmolytes, TaipanOx-ICP antivenom against Papua New Guinea snakes, and other pre-clinical studies. Furthermore, she researches the development of new products from human and equine plasma derivatives. Thanks to her training in bioseparation of biomolecule processes, she has contributed to the development and assessment of a methodology to purify proteins from human plasma derivatives, specifically, immunoglobulin of intravenous use and human albumin.
