The La Jolla Institute for Immunology is dedicated to understanding the intricacies and power of the immune system. Unraveling and recognizing mechanisms is key to be able to apply that knowledge and thereby promote human health and prevent immune system related diseases. Research at the La Jolla Institute is focused on a wide range of immune disorders and diseases, including infectious diseases such as COVID-19, ZIKA, Dengue, tuberculosis and HIV, autoimmune diseases such as inflammatory bowel disease, diabetes, and allergies and cancer immunotherapy.


One of the most valuable tools in immunology research is flow cytometry. This high throughput technology is used to analyze the physical and chemical characteristics of particles – mostly cells - in a stream of fluid as it passes through laser light. Cell components are fluorescently labeled and then excited by the laser to emit light at varying wavelengths. In immunology research and healthcare, flow cytometry has numerous essential applications including cell counting, cell sorting, detection of biomarkers, phenotyping of disease specific cell populations, and clinical diagnostics, etc. With the help of this technology, data of a large number of cells can be ascertained over a short period. Information on the heterogeneity and different subsets within cell populations can be identified and measured and specific signatures deciphered.


The Flow Cytometry Core Facility at the La Jolla Institute for Immunology is one of the largest shared resource laboratories at a non-profit institution in San Diego. The LJI Flow Cytometry Core Facility maintains and supports a total of 19 instruments, including novel high parameter technology such as the Cytek Aurora CS and analyzer and the BD FACSymphony S6, with plans to expand and purchase more instrumentation.  The LJI Flow Core assists over 400 scientists and researchers at LJI, and provides services to UCSD and external collaborators. Our overall goal in the Flow Core is to provide cutting-edge technology and resources along with the expertise to guide and assist new and existing users of our facility (in cytometry related projects)
