View Product โ๐จ What is Cell Painting?
Cell Painting is a high-content imaging assay that uses six fluorescent dyes to paint different cellular compartments. Developed at the Broad Institute, it creates morphological profiles for classifying cellular states.
How Cell Painting differs from standard fluorescence microscopy
Unlike conventional immunofluorescence, which usually targets one or two proteins with antibodies, Cell Painting stains six independent cellular structures in a single round. Each dye highlights a different compartment โ nucleus, endoplasmic reticulum, nucleoli, mitochondria, actin cytoskeleton, and plasma membrane โ so the combined image captures the whole-cell morphology rather than a single marker.
The technique is intentionally unbiased: it does not assume which pathway is affected. Instead, a high-content microscope records thousands of cells, and image-analysis software measures 1,500+ morphological features per cell. These features are compiled into a profile that can distinguish drug mechanisms, genetic perturbations, disease states, and toxicity responses.
Cell Painting therefore sits between simple fluorescence imaging and transcriptomics. It is faster and cheaper than RNA sequencing for many screens, while providing spatial information that sequencing cannot. Typical workflows use 96- or 384-well plates, an automated high-content microscope such as the CellInsight CX7, and open-source analysis tools such as CellProfiler.
The six standard Cell Painting dyes are shown below. Each was chosen for its specificity, photostability, and spectral compatibility in a multi-channel imaging workflow.
๐ต Hoechst 33342
A cell-permeable bisbenzimide dye that binds the minor groove of AT-rich DNA regions. It is used at low concentration for live-cell nuclear segmentation because it is minimally toxic and does not require cell fixation or permeabilisation. In Cell Painting, Hoechst 33342 provides the primary nucleus mask from which nuclear size, shape, intensity, and texture features are extracted.
๐ข Concanavalin A
A lectin conjugated to a fluorophore that binds terminal ฮฑ-D-mannose and ฮฑ-D-glucose residues on glycoproteins in the endoplasmic reticulum and Golgi apparatus. Because these organelles are highly glycosylated, the signal outlines the ER-Golgi network and reports on protein trafficking, secretion stress, and secretory pathway morphology.
๐ก SYTO 14
A cell-permeant nucleic acid stain with higher affinity for RNA than DNA. In Cell Painting it labels nucleoli and cytoplasmic RNA, making it possible to measure nucleolar area and RNA distribution. Changes in SYTO 14 intensity often reflect altered transcriptional activity or ribosome biogenesis.
๐ด MitoTracker Deep Red
Accumulates in active mitochondria in a membrane-potential-dependent manner and is retained after mild fixation. It reports mitochondrial mass, network morphology, and membrane potential. Loss of signal can indicate mitochondrial dysfunction, a common phenotype in toxicity and metabolic disease screens.
๐ฃ Phalloidin
A bicyclic peptide from the death-cap mushroom that binds filamentous actin (F-actin) with high specificity. Fluorophore-conjugated phalloidin reveals the actin cytoskeleton, cell shape, adhesion footprint, and polarity. In morphological profiling, actin features distinguish migratory, spread, or rounded phenotypes.
โช WGA
Wheat Germ Agglutinin is a lectin that binds N-acetylglucosamine and sialic acid residues on glycoproteins and glycolipids. It labels the plasma membrane and Golgi, highlighting cell-cell boundaries, surface area, and adhesion patterns. WGA intensity can also reflect changes in glycosylation during disease or drug treatment.
