Imaging Flow Cytometry: Methods And Protocols -
IFC provides a "visual verification" for every data point, allowing researchers to see exactly what their gated populations look like.
While IFC shares many preparatory steps with conventional flow cytometry, it requires specific optimizations to ensure high-quality imagery.
: Beyond fluorescence, IFC provides data on cell size, shape, circularity, and internal complexity. Imaging Flow Cytometry: Methods and Protocols
: Cells must be in a single-cell suspension to avoid clogging the thin fluidic channels used for imaging.
: Researchers must set specific software parameters, such as magnification and laser power, to maximize the resolution of the captured images. Common Applications IFC provides a "visual verification" for every data
: Non-specific binding is prevented using anti-Fc antibodies. Cells are then stained with fluorophore-conjugated antibodies, viability dyes, or nuclear dyes like DAPI or Hoechst to provide spatial landmarks.
: If internal markers (e.g., nuclear proteins) are the target, cells are fixed with formaldehyde and permeabilized with detergents like Triton X-100. : Cells must be in a single-cell suspension
: Systems like the ImageStream use Charge-Coupled Device (CCD) cameras with Time Delay Integration (TDI) to track cells in flow, preventing motion blur and enabling the detection of dim markers.
