Centre for Advanced Histology and Microscopy
The Centre for Advanced Histology & Microscopy (CAHM) provides researchers with access to equipment for the preparation, visualisation, and quantification of biological specimens at the cellular and subcellular levels utilising advanced histology and microscopy techniques. Our centre is equipped with state-of-the-art instruments and expertise in histology and microscopy fields. Researchers can access the equipment via self-service or engage our experienced centre staff on a fee-for-service basis.

Potential applications
- Evaluate cellular processes including cell-cell interactions, mechanisms of cell death, cell proliferation and differentiation, and intracellular signalling pathways in real time using time-lapse imaging.
- Investigate the mechanisms underlying asymmetric cell division and cell fate determination in real-time over multiple generations with low phototoxicity using the spinning disc confocal microscope.
- Utilise super-resolution microscopy to examine the distribution of specific proteins beyond the resolution of routine confocal microscopes.
- Examine the mechanisms of cancer metastasis, the interaction of immune cells with cancer cells, the development of tumour over time, or the efficiency of chemotherapeutic agents in destroying cancer cells in vivo with the multiphoton microscope.
- Use the SIM scanner on the multiphoton microscope to bleach regions of interest or photoconvert fluorescent proteins in a designated region to examine protein kinetics.
Multiplex Immunohistochemistry and Spatial Multi-omics
Multiplex immunohistochemistry allows simultaneous imaging of multiple antibodies (maximum of 8 markers) on the same tissue section and analyse different biomarkers spatially. We have developed different human and mouse OPAL panels including T cell panel, Pan immune panel and tissue-resident memory T-cells (TRM) panel. We also provide service to optimise your own customised panel with your antibody list.
Spatial multi-omics platforms allow detection of expression of ultra-high plex genomics and proteomics to study multiple molecular layers within cells or tissues while preserving their spatial context. These approaches enable a comprehensive understanding of complex biological processes and disease mechanisms.
Services and support offered
