MIBI™ technology (Multiplexed Ion Beam Imaging) uses Secondary-Ion Mass Spectrometry (SIMS), a type of mass spectrometry traditionally used in the semiconductor industry, to image antibodies tagged with monoisotopic metal reporters.
This unique technology enables:
- Visualization of 40+ markers simultaneously
- Imaging at the sub-cellular resolution
- Detection of low abundance proteins
- Rescanning of slides at multiple resolutions
The system uses a simple, streamlined workflow that adapts easily for both pathology and clinical imaging labs. Samples are prepared using a traditional IHC protocol and data are collected in less than 1 hour using the MIBIscope™ I.
- PREPARE: FFPE tissue preparation follows conventional IHC protocols.
- STAIN: Tissue is stained with a mixture of validated antibodies with conjugated elemental reporters, in one single step.
- DETECT: Stationary tissue samples are raster-scanned with an ion beam and secondary elemental ions are generated.
- IMAGE: All markers are imaged at the same time and detected via TOF mass spectrometry
Highly Multiplexed Tissue Imaging
In a single scan, the MIBIscope™ I can measure
Low abundance proteins such as PD-1 and FOXP3 that can be missed using other techniques are easily detected with the MIBIscope™ I. With no probe background or autofluorescence to interfere with weak signals, the high sensitivity that results ensures all high, medium and low-abundance targets are detected in the same scan.
True Sub-Cellular Resolution
With resolution comparable to light microscopy systems, MIBIscope™ I system lets you analyze and interpret cellular interactions. Cellular structures as small as 250 nm can be imaged, enabling downstream cell segmentation data analysis. Because the MIBIscope™ I doesn’t fully ablate the sample, a survey scan can be done to select specific regions of interest followed by high-resolution imaging.
Rescan Slides at Multiple Resolutions
The system’s imaging workflow enables scientists and pathologists to scan a whole tissue section faster at low resolution, then rescan regions of interest at high resolution. Precious tissue is conserved and may be scanned repetitively.
