Expert insights

Cell-by-cell analysis can help characterize cell subsets and monitor cell behavior in real time. In a recent webinar, Dr. Clare Szybut presented how cell-by-cell analysis enables monitoring and quantification of dynamic phenotypic changes in heterogeneous cell populations and reveals the exciting new software that can make it possible.

Thank you for all your questions. Here are some of the highlights from the Q&A session, which took place over Twitter:

Q: Can the data for individual cells be exported for analysis/visualization in other packages?

A: Yes. Data can be readily exported to packages such as Excel. Due to the large file sizes, each time point is exported as a separate file.

Q: Is the Fab-based antibody labeling approach suitable for use on other platforms, such as flow cytometry.

A: Yes. The phenotyping validation data of PBMCs was achieved using the FabFluor488-Ab labeled cells on a flow cytometry instrument.

Q: Will the software module enable segmentation of adherent cell types?

A: No. At present, the module has not been developed or validated for use with adherent cells. However, that is an obvious area of interest.

Q: What is the mask?

A: The mask refers to the segmentation of the phase image enabling each cell to be identified.

Q: Have you used this technology for any primary cells?

A: Yes, we have used live-cell imaging extensively with PBMC and isolated cell types from the blood.

Q: If I have two cell lines, one labeled with GFP and the other RFP, can this system detect the two cell types, monitor growth and roundness?

A: Yes, this would be an ideal set-up for this new software module.

Q: What is special about these antibodies, apart from being non-toxic?

A: There is nothing special about them, but they have been labeled with IncuCyte FabFluor-488 for detection. We do recommend you purchase low azide containing antibodies.

Q: What do you do to keep suspension cells centered in the wells? We have problems with cells moving towards the edges of the wells.

A: We have observed similar issues. Routinely, we coat our plates with PLO to reduce this issue. Please see the Essen BioScience website for full protocols and details of the use of non-adherent cells with IncuCyte.

Flow Cytometry / Cell CountingFlow cytometers are used to count, sort and examine multiple characteristics of cells. Other cell analysis equipment includes image cytometers, cell counters, fluorescence-activated cell sorters (FACS), magnetic-activated cell sorters (MACS), and a range of flow cytometry assay kits. Flow cytometers can reveal information on cell viability, cell proliferation, apoptosis and cell cycle progression, as well as identify cell populations and intracellular or cell-surface molecules. Additionally, some flow cytometers, known as FACS, have an additional sorting function after analysis. Cell counters and image cytometers count live and dead cell populations and can also conduct cell proliferation assays. Find the best flow cytometers, cell counters and cell sorters in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Cell-Based AssaysCell-based assays are used to monitor the presence, quantity and activities of a desired cellular analyte including drug molecules or biomarkers. This can reveal information on cell health (apoptosis, cytotoxicity, viability and proliferation assays), cell metabolism, cell migration and cell signaling mechanisms. Find the best cell-based assay products, kits and equipment with our peer reviewed product directory: compare products, check customer reviews and receiving pricing direct from manufacturers.Cell AnalysisThe analysis of cells allows researchers to understand the factors which contribute to cell health and function. These influencing processes can then be predicted and altered, leading to the development of medication and disease treatments.Live Cell ImagingLive cell imaging is the study of living cells using microscopes and high-content imaging systems. This technique provides in-depth insight into fast and complex biological processes, by allowing dynamic imaging of living cells instead of acquiring an individual image at a single point in time.
