Mauren Villalta Arrieta

Mauren Villalta Arrieta coordinates the Quality Control Section. Her work focuses in coordinating and supervising the Quality Control activities of the Industrial Division for the production of antivenoms and new immunobiologicals. Her researches focus on the improvement of the efficacy and safety of the immunobiologicals produced and in the development of new products to help resolve human and animal health problems related to envenomings by snakebite or by the action of other venomous animals, or the infection of pathogen microorganisms. For this, she develops activities like the assessment of the physical-chemical and biological characteristics of antivenoms, among them the neutralizing potency of toxic activities and protein aggregates, she develops immunization schemes, assesses adjuvant agents and the stability of products, and studies the activities and composition of venoms, among others.
