The Quantitative Light Microscopy Shared Resource (QLMSR) provides affordable access to a variety of state-of-the-art optical microscopes to support the cancer-focused research of Simmons members. The QLMSR team consults with new and current users, provides customized training, and advises on sample preparation, data acquisition, and data analysis.


QLMSR has capability for wide-field, confocal and TIRF imaging of live and fixed samples, including immunofluorescence, fluorescent expression tags, and cleared tissues. The Shared Resource provide instrumentation and expertise that permit multiday, time-lapse imaging of live samples. It provides instrumentation for two photon intra-vital imaging of whole animals and organs, including second harmonic generation for visualizing collagen, muscle, and bone in unstained samples.

QLMSR is the primary source for high-quality super-resolution imaging on the UT Southwestern campus and receives significant institutional support as well as support from the Simmons Cancer Center. It provides microscopes capable of true color imaging of histologically stained samples, polarization microscopy, and stereo fluorescence microscopy. It is the only source at UTSW of instrumentation for fluorescence correlation spectroscopy (FCS) in cells and solutions.

Members are provided with access to powerful workstations and software for image processing and data analysis. They also work with users to develop customized image acquisition and analysis pipelines, including colocalization, single particle tracking, and object counting.

An additional service made possible by QLMSR, in conjunction with the UTSW Electron Microscopy Core Facility, is correlative light and electron microscopy. Also, a new service is a collaboration with UTSW Microscopy Innovation Laboratory (MIL) to fast track access to cutting edge microscope technology for Simmons Cancer Center members.
