Service Profile

Biorepository

The Biorepository contains plasma, serum, RNA stabilized buffy coat, urine, viable tumor samples, and formalin-fixed paraffin-embedded tumor — all with associated clinical information. These can be provided to investigators with Cancer Sample Banking Committee approval. (IRB approval is also required for projects requesting ongoing sample collection or clinical annotation.) Urine and blood-derived specimens are available from a wide variety of cancer cases and cancer-free controls. Tumor sample availability is more limited. Samples are collected from consented subjects, and de-identified clinical information on the subjects is available. Subjects are consented for research germ line genotyping. Access to the clinical annotation is determined based on need as justified in each investigator's request or protocol.

Anonymized samples from the biorepository are available compliant with UC San Diego HRPP exempt category 4.

For projects requiring ongoing sample collection or clinical annotation, Human Subjects Research Review is required. For outside users, the biorepository can assist with identifying a UC San Diego clinical investigator to collaborate on this process.

Tissue Technology Biomarker

Biomarker analysis on intact tissue can be performed using three different modalities:

  1. Immunohistochemistry
  2. Immunofluorescence
  3. In situ hybridization using multiple detection systems

The tissue technology center uses a fully automated Ventana Discovery Ultra slide preparation system that can reproducibly perform ICH, ISH, FISH and Qdot immunofluorescence techniques on the same instrument platform. This permits time-effective optimization of the most sensitive/specific detection method for any biomarker. IHC, ISH, FISH, and FITC tests may be performed independently or simultaneously. The capability to perform IF and FISH technique on the same tissue section permits the greatest flexibility in the localization of biomarker expression. The system provides extensive options to perform multiple assays (up to 30 slides per run) for more accurate semi-quantitative Immunohistochemistry / immunofluorescence and an efficient capability for methods development to validate and to develop new biomarkers."

Histology-Immunohistochemistry

A phenotypic evaluation of animal models of human disease is critical in the understanding of the pathogenesis and the processes involved. A careful examination (always with the organs and tissues from littermate controls) of completely back-crossed genetically altered mice, at different ages, is required . A comprehensive histopathologic review, hematology analyses, chemistry panels and a variety of behavioral tests will help to accomplish some of these goals. The histotechnologists and the experienced pathologist in this sub-core educate and facilitate a thorough histologic and immunohistologic comparative analysis of tissues from wild type and genetically altered mice, and especially focuses on mouse models of human disease.
