The Flow Cytometry Core Facility provides cell sorting services and access to routine flow cytometry assays, such as immunophenotyping and DNA analysis, and guidance, technical assistance and equipment for the investigators to utilize more complex mult-parametric, multi-laser measurement and cell sorting in their research. The recent acquisition of the MoFlo high-speed sorter has increased the facilities technical capabilities. The facility serves as a focus for studies of cellular heterogeneity in disease. Services range from consultation on experimental design, sample preparation and data analysis to instrument operation and set-up for cell sorting and multi-laser operation.
