The Microm HM500 M includes a motorized drive and uses a steel knife blade which is advantageous for large and stiffer samples. Users must provide their own steel cryo knives (See the MICF staff for recommendations on the size and profile of knives to purchase. They can also suggest resharpening services).
The Leica CM3050 S includes as a standard feature, a sectioning motor, ensuring fatigue-free ribbon sectioning. With the reverse section counter a preselected number of sections can be carried out in both sectioning and trimming mode. Section thickness totalizer and counter with reset button facilitates target preparation promoting fast trimming between levels.
The Leica Cryostat uses disposable blades which are ideal for high throughput users cutting small samples.
For training on the Microm, please see Rhonda Grebe; for training on the Leica, please see Stacey Cole.

Features include:
This instrument has made FACS work much easier by using disposable flow cells and an automated cell loading and flow alignment system, thus it is possible to perform sophisticated sorting without a dedicated operator.
The system is supervised by Dr. Berlinicke, but with a half day of training, a number of other users have been able to successfully utilize the system for sorting for proteomic and genomic analysis, and subsequent cell culture.

The Cellomics ArrayScan VTi (Thermo Fisher Scientific) is a robotic, fluorescence-based, imaging system. It contains Zeiss microscope optics and a Hamamatsu ORCA-ER cooled 12 bit grayscale CCD Camera.
It automatically acquires multiple images per well from most standard microwell plates and microscope slides. These images are stored on a Dell 20-terabyte server and analyzed with custom algorithms that are created using various Cellomics image-analysis software packages (Bioapplications). Among the eighteen Bioapplications that we have are Neuronal Profiling, Cell Cycle, Cell Health Profiling, Cell Motility, Compartmental Analysis, Spot Detector, and Morphology Explorer.
With the diverse repertoire of algorithms available, we can quantify almost any cellular phenotype. The data obtained by these analyses is fully integrated into a complete data management system (Store). In addition to the scanner hardware, we also have available the brightfield module, and the Live-Cell module.
This instrument is under the supervision of Dr. Cindy Berlinicke.

The Leica LDM500 is a contamination-free, fully automated laser microdissection system for targeted cell isolation using gravity and a UV diode laser. Single cells or groups of cells can be microdissected from tissue sections, biopsies, smears, cytospins, and cell cultures.
The laser can be also applied for intracellular and cellular ablation. Nucleic acids and proteins specifically isolated from the dissected specimens can be directed to molecular analyses such as: sequencing, genotyping, PCR, real-time PCR, 2D gel electrophoresis or MALDI.
Please contact Stacey Cole for training.

The Invitrogen EVOS™ FL Auto 2 Imaging System is a high-performance, fully-automated, inverted, multi-channel fluorescence and transmitted light imaging system, ideal for tissue culture studies in well plates.
Please see Dr. Berlinicke for training.
