Provides a wide range of sample characterization techniques for UCLA researchers, other academic institutions, and commercial enterprises.
Materials Characterization Laboratory
1045 Young Hall
Enables thermal, optical, microscopic, electrical and magnetic characterization of materials and elemental analysis of surfaces.
The UCLA Metabolomics and Proteomics Center enables investigators to study metabolism with a particular focus on central carbon metabolism (glycolysis, pentose phosphate pathway, TCA cycle, nucleos(t)ide synthesis, etc.). Metabolite analysis can be performed on a variety of specimens (e.g. cultured cells, culture medium, blood, urine, tissue). Generally, relative amounts of metabolites are measured, but absolute amounts can be determined as well. Tracing experiments using stable isotope-labeled metabolites (D, C-13, N-15) are routinely performed. For data analysis, relative amounts of metabolites as well as mass isotopologue distributions (if isotope tracing was performed) are calculated. Results are illustrated using bar graphs, heatmaps, principal component analysis, and mapping to Cytoscape maps.
The MSSR is a core facility open to all research labs on campus. The services provided include the use of high throughput screening (HTS) technology, a total of roughly 200,000 compounds in various libraries, siRNA sets of the druggable genome for mouse and human and a database of results from screens. Please use the links above to find out more about the MSSR. The MSSR is currently funded by the JCCC, the Department of Molecular and Medical Pharmacology, the Department of Microbiology, Immunology and Molecular Genetics, and the Dean’s office, David Geffen School of Medicine and the California NanoSystems Institute.
Provides consultation, training, and access to and technical assistance for metabolomics, proteomics (top-down and bottom-up) and targeted small molecule quantitation using mass spectrometery and contemporary chromatography.
Peptide Synthesis Core Technology Center
The Peptide Synthesis Core Facility (PSCF) contains a dedicated fume hood for peptide deprotection and cleavage. The facility assists investigators performing multifaceted investigations of peptides by providing peptides that are difficult to synthesize, fold, and purify (e.g., beta-sheet peptides with multiple disulfide connectives, cyclic peptides, or amyloid peptides). In addition, the PSCF can synthesize isotope-edited versions of proteins and peptides suitable for detailed determinations of 3-D molecular structure by NMR spectroscopy or X-ray diffraction.
The Protein Expression Technology Center (PETC) was founded in 1994 to facilitate the expression and purification of proteins for structure/function studies. The PETC provides support in all aspects of protein expression from cloning through expression optimization and protein purification. The PETC is a UCLA-DOE Institute for Genomics and Proteomics facility but is open to all researchers.

The UCLA Proteome Research Center is a full-service technology center that offers a comprehensive suite of proteomic services to the UCLA community and other partnering institutions. By bringing together state-of-the-art instrumentation and high-level technical staff, the goal of the facility is to transform traditional experimental paradigms by providing investigators access to powerful analytical workflows for systems-level characterization of complex biological systems, biomarker discovery and validation, and protein complex characterization. Available services include: (1) complex protein mixture analysis using single and multidimensional fractionation strategies, (2) peptide quantitation using SILAC, iTRAQ / TMT, and label-free methodologies, (3) targeted and global PTM enrichment and characterization approaches, (4) identification of protein interaction networks using affinity-based isolation and proximity tagging techniques, and (5) targeted proteomic assay development using parallel reaction monitoring (PRM) for relative and absolute quantitation.
Surface Plasmon Resonance Core
The Surface Plasmon Resonance Core consists of a Biacore 3000 instrument that uses a powerful technique called surface plasmon resonance (SPR) to monitor binding interactions between two molecules. The Biacore 3000 instrument provides precise, sensitive, real-time results, using microgram amounts of non-radiolabeled samples. In its ligand-recovery mode, the instrument can be used as a nano-affinity column to recover binding partners from crude mixtures of potential ligands. Its robotic recovery feature precisely transfers recovered samples to plates suitable for MS analyses. Services include: (1) selection and preparation of the biosensor chips using investigator-supplied proteins, (2) running binding assays at various analyte concentrations, (3) calculating the binding constants, (4) providing the raw and analyzed data to the investigator, and (5) discussion of the results.
