Grupo Proteómica




Head of Unit: Gemma Barroso García



Proteomics Unit's mission is to make available to researchers techniques based on protein analysis, focusing on finding appropriate experimental designs and implementation of new technologies in the field of proteomics.


The Unit has the necessary instrumentation to perform separation experiments, quantification, identification and characterization of proteins, as well as for conducting studies of biological and biomedical interest by means of electrophoresis and mass spectrometry. Likewise, proteomics techniques are also valid in clinical research studies.


Since 2008 the facility participates in the continuing education program of the National Hospital of Paraplegics-SESCAM, offering an Introductory Course to Basic Proteomics.
