Mass cytometry instruments represent an alternative technology to flow cytometry, utilizing heavy metals conjugated to antibodies instead of fluorescent molecules for cell phenotyping with minimal spillover. With ongoing advancements in mass cytometry technology, up to 50 antibodies can now be interrogated on millions of individual cells. At SIgN, two HeliosTM Mass Cytometers and a HyperionTM Imager are available, which enable immunoprofiling of suspension cells and tissues. We enable comprehensive immunophenotyping, immuno-monitoring, and specific cellular analyses of immune responses.
Helios- Suspension Mass Cytometry
Our predefined Suspension Mass Cytometry panels are not limited to:
- Immunophenotyping & Exploration of Novel Cell Populations
- Discovery of Antigenic CD8+ T cells with our customized MHC-I Tetramer panel
- Disease orientated such as T cell oncology, COVID and Allergy
For more detailed information, please refer HERE.
If your targets of interest are not covered by the SIgN predefined panels or if you would like to integrate specific probes other than antibodies, we can work with you to customize a panel that suits your specific research needs.
For more details, contact SIgN_IMP@Immunol.a-star.edu.sg
Hyperion- Imaging Mass Cytometry
When used alongside HeliosTM, the HyperionTM Imaging System uses a one-step staining and detection approach that enables samples to be simultaneously stained, acquired, and analyzed. Standardized Panel kits are available HERE.
Feel free to reach out to us if you have any enquiries about customizing your panel.
