Imaging Flow Cytometry: Methods And Protocols May 2026

: Cells must be in a single-cell suspension to avoid clogging the thin fluidic channels used for imaging.

: Beyond fluorescence, IFC provides data on cell size, shape, circularity, and internal complexity. Imaging Flow Cytometry: Methods and Protocols

: It allows for the quantification of intracellular features, such as the translocation of signals into the nucleus or the internalization of particles. Key Protocol Steps : Cells must be in a single-cell suspension

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

: 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.

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.
