The CyTOF Helios analyzes cells labeled with stable heavy metal isotopes using state-of-the-art time-of-flight atomic mass cytometry technology. Single-cell experimentation methods provide critical advances for research in cancer, cardiovascular biology, embryonic stem cells and development, hematopoietic stem cells and progenitors, immunity and infectious disease.
- Multi-parametric single cell data, deep profiling
- Detect up to 42 parameters simultaneously in a single sample
- Detect more from limited samples
- Advantages over traditional flow cytometry: No background, no overlap between channels, no compensation issues
- Now available for tissue sections with Imaging Mass Cytometry (IMC)
"In house" in our core we maintain:
- a repository of well-characterized metal conjugated antibodies
- metal labeling reagents for conjugation of antibodies to these metals: 145Nd, 148Nd, 158Gd, 160 Gd, 164Dy, 165Ho, 171Yb, 173Yb.
- Metal conjugated anti-fluorochrome antibodies (e.g. anti-FITC) that can be used with existing fluorescent reagents.
- CyTOF Antibody Panel Guide
- Individual metal-conjugated individual antibodies (>500) and panel kits are available from Fluidigm
- Cell Surface Staining Protocol for CyTOF2 Mass Spectrometry
- Sample preparation using barcoding for CyTOF
- Useful web links for new users
All infectious, human, and non-human primate cells must be fixed before they are analyzed on the CyTOF.
CyTOF analysis is available to Yale University investigators as a fee for service. Non-Yale users will be accommodated as possible. Please contact Dr. Montgomery.
