Introduction In molecular pathology and life sciences research, laser microdissection is an essential technology for the isolation of cells and tissues for further downstream analysis. Laser microdissection enables early diagnosis of cancers and neurological disorders, and it is now established as a step towards personalized medicine. MMI has developed a laser microdissection technology with unmatched precision and speed where sample isolation is absolute contamination free. The result is a verified sample collection with a high degree of efficiency combined with reproducibility and least sample damage. This creates unique prerequisites for successful downstream applications. Furthermore, MMI instruments are highly modular and can be mounted on numerous microscope brands. 3

From routine to most complex laser microdissection MMI CellCut The MMI CellCut was designed for the quick and precise isolation of cells and tissue and so is an essential tool for molecular pathology. A wide variety of sample types including fresh frozen, paraffin embedded, archived slides, cytospins, smears and live cells can all be used for diagnostic purposes. The MMI CellCut enables cell selection quickly and easily directly on the touch screen. The cells of interest are marked and cut automatically using a precisely focused UV-Laser. The microdissected samples are collected for downstream analysis. This results in a pure cell population for reliable analysis and diagnosis. The MMI CellCut is highly modular and can be mounted on numerous brands of microscope from entry level, mid range to high end, suitable for the most routine to the most complex research applications. Setup • Based on an inverted or upright, manual or motorized, entry level or high end microscope • High precision motorized scanning stage • Electronically controlled solid-state laser (optional with high power for thick, hard, or wet tissue), laser beam delivery and transfer optics • MMI CapHolder with MMI Single CapLift, MMI MultiSlide insert for parallel us of up to 3 slides, MMI LiveCell insert for applications with living cells, optional with MMI Multi CapLift for the parallel use of up to 8 caps • High-resolution MMI CellCamera • Modular and upgradeable workstation • MMI CellTools software for full control of the laser, image capture, and scanning stage actions combined with MMI CellExplorer software for automatic cell recognition in fluorescence or bright field • Interactive LED pen display MMI CellCut on Olympus IX83 motorized inverted microscope Interactive pen display and intuitive MMI CellTools software MMI controller unit 4

Sample preparation The section is placed on the MMI MembraneSlide, a frame slide covered with a thin membrane that is inert and has negligible auto fluorescence. Afterwards the MMI MembraneSlide is inverted and placed onto a glass slide for protection against contamination. Now the sample is sandwiched between the membrane and the glass. 2. Easy cell selection The cells of interest can be selected on the display using either the mouse, by freehand or predefined geometrical shapes which can be modified. Any number of cells across the slide can be identified as targets within one screening process. The stage is moving to trace the path drawn and the laser is fixed and focused from below. 3.

MMI CellCut: Unique features & benefits Contamination free cutting The sample is sandwiched between a membrane slide and a glass slide and so it is not exposed to the air. This ensures a safer working environment and better sample integrity. The thinnest cleanest cut MMI uses a solid state UV-laser with higher pulse rate and lower power. The result is a sharper and cleaner ultra precise cutting line of 0.3 microns and least sample damage. Maximum sample collection The unique MMI CapLift technology enables highest sample collection efficiency and minimal sample damage. The yield can be verified during and after isolation. Predefined Target Positioning (PTP) PTP is a patented product feature that allows for the precise, predefined, contamination free visually controlled collection of individual cells on the cap. PTP is excellent to maximize the number of samples collected into a single reaction tube. It guarantees that the isolated samples are not compromised by subsequent cutting which is essential for auditability. Contamination free collection The MMI IsolationCap is only in contact with the membrane and never in direct contact with the tissue. Positive sample inspection Firstly an overview of the entire sample is produced. Secondly visual inspection and selection of the target cells is performed. This step can be fully automated, using the MMI CellExplorer software. Switch to PTP mode and cells are dissected and collected on the adhesive cap in a spiral pattern starting from the centre of the cap. This feature ensures the sample collection after every laser cut. The isolation of the target area occurs in the same relative position as on the slide. The morphology of the sample remains 100% intact and damages of the surrounding tissue are prevented. Reproducible results are achieved easily and effectively. This is excellent for auditability and accurate quantitative results. Autodocumentation The MMI CellCut allows full verification and traceability of every cut. The autodocumentation feature records images showing the position of the cut and of the collection (PTP) on the cap together with the time, date and method details. 6

MMI LiveCell Chamber Z-drill By this feature, thick and wet tissue can be cut without using a high power laser. Refocus the laser on different z-levels whilst cutting to minimise the use of excessive laser power and so preserve your sample and maximise its usability for downstream analysis. An optional high power laser is available for working with harder to cut material such as teeth, bones, or forensic tapes. The low power laser allows an gentle cut. In specially designed MMI LiveCell Chamber even live cells can be microdissected, for unrivalled success in re-culturing and cloning. MMI CellTools software All MMI instruments come with the intuitive MMI CellTools software package which generates a live view of the entire sample. High quality components such as the MMI CellCamera ensure high resolution and real time application success when working with a wide range of delicate sample material. The MMI CellTools software and corresponding Plug-Ins provide full control of the system. Adjusting the xy-stage, camera, laser and lighting conditions is easy and convenient. Automated microscope functions such as objective or fluorescence turret changes can quickly be initiated directly from the software making full remote control possible. MMI MultiCap & MMI MultiSlide The MMI MultiSlide allows for the isolation of cells from up to three slides and the MMI MultiCap for the isolation of cells into up to eight individual caps without the need to reload. This is essential for diagnostic workflows involving RNA isolation, where speed is of the essence. Serial section This feature maximises the RNA recovery by minimising the use of staining. The visible position of target cells is used on a stained section to detect, mark, cut and isolate regions of interest on an unstained section. The MMI CellTools software for easy and convenient laser microdissection provides a live view of the whole sample 7

MMI CellCut Plus: A wide range of applications The starting materials The MMI CellCut is an extremely versatile instrument and therefore the best choice for clinical and research microdissection. Whether isolating cells from an entire tissue, maintaining a pluripotent stem cell line, or extracting cells for forensic investigation, the MMI CellCut performs efficiently and reproducibly. Pathological samples Isolation of intestinal gland from transverse tissue sections of colon (H&E stained) Cryo or paraffin-preserved tissue Chromosomes Single cells, smears or cytospins Others, e. g. sperms, C. elegans Targeting specific cells in healthy and diseased tissues is of particular importance in elucidating the molecular mechanisms that leads to cancer and other life threatening diseases. Differences in genomic (DNA/RNA) and proteomic expression of any tissue type can be analyzed easily. For example, transverse sections of intestinal glands from colon tissues can be identified and quickly isolated for the study of specific genes and the corresponding hormonal response. Fluorescence-labeled cell components Live cells Fluorescence-labeled chromosomes Cell culture in phase contrast observation The precision of the MMI CellCut enables the simple location and microdissection of subcellular structures. For example, chromosomes with detectable fluorescence in situ hybridization (FISH) signals can be isolated for subsequent investigation. Most stem cell lines are grown at high densities on mouse fibroblast “feeder layers”. Therefore, isolating specific pluripotent cells from the surrounding fibroblasts and differentiating cells needs to be fast and precise. The MMI CellCut offers the perfect balance between speed, precision and ease of use, allowing the target stem cells to be isolated and re-cultured without any side effects, such as karyotype changes. 10
