Dissection Perfection

The most gentle microdissection

Isolate your sample without any degradation and ensure meaningful downstream analyses in genomics, transcriptomics, proteomics, lipidomics and metabolomics. The cleanest laser microdissection on the market is enabled by the maintenance-free MMI laser. The low pulse energy laser (less than 500 ps) creates a very precise cutting edge (up to 0.3 µm) and therefore protects the surrounding area and biological information (RNA, DNA, Proteins).   

Move the stage and your laser is always in focus

By moving the stage and not the laser we ensure that the laser beam is always in focus. Other laser microdissection systems which move the laser can only cut samples in the field of view – leading to inaccurate cutting results.

  • Most accurate and precise cutting system on the market
  • No sample degradation for meaningful downstream applications

Visual Inspection of your Cells

Visual Inspection with the MMI CellCut Microdissection system

Where is my sample?

The MMI CellCut laser microdissection allows a full visual inspection of your sample during and after isolation. The unique MMI CapLift technology makes this possible. The CapLift technology uses an adhesive surface that keeps the sample in place during cutting. The orientation of the cell will be maintained, which allows you to easily verify the presence of the dissected area in the Isolation Cap. Furthermore, you can keep your sample in place during cutting to prevent single cells from flipping away. You will love this feature for your work on rare cells, and so will your reviewer!

  • Always check your cutting efficiency
  • Gentle, contamination-free and highly efficient sample collection with MMI CapLift technology
  • Gravity is not used for collection (Gravity allows no sample inspection and can damage the collected sample)

Cut it all

Microdissection for almost any type of sample

With the MMI CellCut, you can dissect fresh frozen tissue, FFPE material, plant tissue, living cells, smears, cytospins and more.


Thick tissue is no problem

Do you need to cut thick or wet tissue? No problem! The “Z-drill feature” allows to refocus the laser on different z-levels. Therefore, you minimise the use of excessive laser power and so preserve your sample and maximize its usability for downstream analysis. An alternative high-power laser is available to cut very hard materials such as teeth, bones or forensic tapes.


Size does not matter

Dissect single cells or huge tissue areas – even beyond the field of vision. The precise laser is fixed while the stage is moving during laser cutting, thus the laser will always be in perfect focus, even with larger tissue areas.

Microdissection for any type of sample

Gotcha! MMI CapSure technology captures cells like a “ninja"

CapSure Technology from MMI

Enhancing precision in sample collection

The MMI laser capture microdissection system used the patented CapSure technology for the precise and contamination-free isolation of specific cells or regions of interest from tissue samples. The CapSure technology used a small adhesive cap, which automated the transfer of the target sample from the slide into a microcentrifuge tube (Isolation Cap). The Isolation Cap only gets into contact with the membrane – the sample itself is not touched. Therefore the sample can be handled free of contamination.

The gentle cutting and the transfer without unnecessary induction of physical or chemical forces leads to meaningful results for any downstream applications.

  • With CapSure you can always check your cutting efficiency
  • Contamination-free cutting
  • Gentle transfer of cut samples to ensure meaningful downstream applications

Boost Your Microdissection Efficiency

MMI CellCut with a MultiSlide

Predefined Target Positioning
The Predefined Target Positioning (PTP) feature allows a contamination-free and controlled collection of individual cells on the Isolation Cap. PTP is excellent to maximize the number of samples collected into a single reaction tube, guarantees isolated samples are not compromised by subsequent cutting and is essential for auditability.

MMI MultiCap and MultiSlide
The MMI MultiSlide enables you to process multiple samples in a single run, saving time and increasing efficiency in the laser microdissection workflow. You can isolate single cells into up to eight individual caps without the need to reload. The MultiSlide can also be used to analyze multiple regions within a single sample, allowing for a more comprehensive analysis of tissue or cell heterogeneity.

What is Laser Capture Microdissection?

Laser Capture Microdissection is defined as the precise cutting of microscopic tissue area using a laser and the subsequent separation of the dissected area from surrounding tissue. Importantly, laser dissection microscopes differ in the particular method to isolate target cells after cutting. MMI for example isolates cut tissue by employing adhesive isolation caps, which gently and reliably take up the sample of any size and shape.

How does Laser Capture Microdissection work?

Typically, laser capture microdissection systems are based on research microscopes. Lasers are required to precisely cut tissue on this microscopic scale, and they are coupled into the optical paths of the dissection microscopes. For cutting, the sample is mounted on membrane slides to enable both for precise cutting and for subsequent cell isolation procedures.

The laser microdissection microscopes on the market today mainly differ in the laser types they use and how the laser is applied to cut the sample. The MMI CellCut uses a low-damage laser with low power but high pulse frequency to allow for efficient and precise cutting and to not compromise tissue integrity. Moreover, the laser is fixed during the cutting process to ensure that the laser is always in focus and the sample is efficiently cut.

What are the potential applications of Laser Capture Microdissection?

Applications for Laser Microdissection

Laser Capture Microdissection offers a huge range of applications since a plethora of different sample types can be processed. Several applications originate from pathology where diseased tissue is separated from healthy tissue for molecular analysis to make a better diagnosis, as this is often the case for highly heterogeneous tumour tissue. Since any type of human tissue, even bone tissue can be cut by laser dissection, laser capture microdissection is widely applied in cancer research, oncology, neurology, infection research, immunology, stem cell research, developmental biology and many other research areas in biomedicine. Importantly, laser microdissection adds spatial information to the molecular data of individual cells thus providing an extra dimension to omics research.

Moreover, laser capture microdissection is also a valuable tool in crop science and plant research as this technology can cut different types of plant tissue. In addition to basic and clinical research, laser capture microdissection is applied in diagnostics and forensics. Thus, laser capture microdissection is a very versatile technology with a tremendous range of applications.

How efficient is laser capture microdissection for single cells?

The laser capture microdissection technology has improved over the last year to make the cutting process more reliable and more precise. Thus, also single and rare cells can be excised from tissue sections, living cells or smears and swabs.

Interestingly, the MMI CellCut microdissection microscope is highly optimized to specifically cut single cells. The low-damage laser allows to cut single target cells without impairing their DNA or RNA quality, or the integrity of living cells. To be able to cut single living cells, MMI also offers a range of dedicated consumables. Thus, physiological conditions and contamination-free handling is supported throughout the experiment.

Intriguingly, the patented adhesive cap technology used by the MMI CellCut allows to keep the tissue in position during cutting. Thus, excised tissue cannot drop off because of airflow or static forces, a phenomenon that often occurs with dry sample of very small sizes such as single cells. Moreover, the different objectives and fluorescence filters implemented in the laser dissection microscope can be combined and optimally employed to identify and select single target cells. Image analysis tools integrated into the MMI CellTools software package allow to find even very rare cells in the sample

Laser Microdissection for Single Cells

The MMI CellCut provides a fully auditable and automatically documented workflow:

CellCut Workflow

1. Sample Preparation: The tissue sample is first prepared for microdissection by fixing, embedding, and sectioning it into an inert membrane slide with negligible autofluorescence. Afterwards, the membrane slide is inverted and placed onto a glass slide for protection against contamination.

2. Cell Selection: The cells of interest can be selected on the computer screen using either the mouse, by freehand or by predefined geometrical shapes. Any number of cells across the slide can be identified as targets within one screening process.

3. Laser Cutting: Once the region/cells of interest have been identified, the laser is focused on the selected area. The thin laser cutting path enables a precise and gentle extraction at an outstanding speed.

4. Collection & Inspection: The isolated target cell is collected by an adhesive cap. The orientation and morphology will be maintained. After cutting the cell can be visualised on the cap.

5. Ready for Downstream Processing: After microdissection, the collected cells can be processed further for any downstream application (e.g. gene expression analysis, RNA isolation and much more).

“We appreciate the resistant MMI product quality, the professional consulting, and the competent and quick service. MMI instruments are an important basis for our in-situ analysis in cellular tissue. The MMI CellCut laser microdissection followed by gene expression analysis is complementary for further routine methods like conventional optical microscopy (fluorescence), in-situ hybridization, and immunohistochemistry.”
