Core Facilities

TTUHSC Image Analysis Core Facility (Lubbock Campus) - The newly created Imaging Facility (1,200 square feet) has recently purchased the IVIS Lumina XR from Caliper Life Sciences for real time tracking of cells expressing bioluminescent or fluorescent proteins simultaneously with X-ray digital imaging technology for living mice. We also have in that facility two fully equipped laser scanning confocal microscopes.  One of these confocal microscopes is a newly acquired Nikon Ti-E microscope with A1 confocal and STORM superresolution.  The other is a Zeiss LSM 510/Meta confocal system attached to both inverted and up-right microscopes. The Nikon system is equipped to perform spectral imaging experiments, TIRF and FRAP. A high temporal and spatial resolution EMCCD camera is attached to this system. The microscope is also equipped with a stage-top environmental chamber in which precision temperature incubations can be performed. In addition, we also have up-right and inverted fluorescence microscopes attached to a CCD camera  for routine observation of stained (fluorescence) or unstained (Differential Interference Contrast, DIC) specimens.  Link: Image Analysis Core Facility

TTUHSC Molecular Biology Core Facility - Mission:  The TTUHSC Molecular Biology Core Facility provides state-of-the-art instrumentation to support experimental demands in molecular biology, ranging from routine bacterial cell growth, monitoring of mammalian cell growth, advanced approaches for cell transfection, monitoring protein and gene expression, RT-PCR, flow cytometer and cell sorting capabilities, exon amplification and single cell separation for whole genomic analysis. Expertise and advice is available for the design of experiments using these approaches and technologies.

Services and Available Equipment:  The Molecular Biology Core Facility has a Meso Scale Discover Sector Imager that uses multi-array approaches enabling the detection of bio-markers in single and multiplex formats. For quantification and analysis of DNA, RNA and proteins we have the ImageQuant LAS 4000 digital imager and the Typhoon FLA 9000 Biomolecular Imager for quantitative imaging of chemiluminescence, fluorescence, and gel documentation. The 2100 Bioanalyzer (Agilent) it uses microfluidics to run DNA, RNA and proteins samples and replaces agarose gels and SDS-PAGE. The Infinite M1000 PRO quadruple monochomator microplate reader (Tecan) is used to measure UV, VIS absorption, and a variety of fluorescence-based approaches with high spectral resolution. For transfection of cells with DNA or RNA, we have the 4D-Nucleofector Core X/Y (Lonza). For cell growth (mammalian cells in suspension, bacteria and yeast) we have the Biolector MP2 that allows continuous monitoring of growth mass, fluorescence, acid production and oxygen consumption in multi-well format. For analysis of gene expression, micro RNA profiling and non-coding RNA analysis we have the Quant Studio 12K real time PCR (Life Technologies). High throughput target enrichment (exons) and amplicon tagging is performed with Access Array (Fluidigm). The C1 Single Cell auto preparation system (Fluidigm) allows us to study in single cells gene expression and mRNA analysis in a 96 well format. A very simple image cytometric analysis to study apoptosis, cell cycle analysis, cell proliferation, viability assays and cell counting is performed using the Cellometer from Vision Image Cytometry. High resolution microscopy in flow (ImageStream MarKK II, Amnis) is used to evaluate microscopically the localization of subcellular proteins with a high throughput approach using fluorescently labeled samples. The BD FACSJazz cell sorter and the BD Accuri C6 flow cytometer allows to perform cell sorting and study many cellular functions including apoptosis, cell cycle, cell proliferation, cell phenotyping.
