Imaging Flow Cytometry (IFC) is a hybrid technology that combines the of conventional flow cytometry with the detailed spatial and morphological resolution of digital microscopy. Unlike standard flow cytometry, which provides integrated signal intensity for a whole cell, IFC captures multiple digital images of every individual cell as it passes through the system. Core Principles and Advantages

: 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.

: Researchers must set specific software parameters, such as magnification and laser power, to maximize the resolution of the captured images. Common Applications

: If internal markers (e.g., nuclear proteins) are the target, cells are fixed with formaldehyde and permeabilized with detergents like Triton X-100.

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.
