Immunocytochemistry is a fixed-cell, antibody-based method used to visualise and localise proteins within individual cells. Applications include single-marker assays, co-localisation studies, and morphology-linked readouts that support assessment of cell identity, phenotype, and maturation state.
Reliable ICC data depend on well-defined marker expression, high-quality antibodies, and well-established immunocytochemistry protocols. ioCells offer a highly characterised, predictable starting point—supported by expert ICC guidance and validated antibody recommendations—helping make ICC workflows more robust and reducing unnecessary repeat optimisation.
Consistent cells
Reduce repeat ICC by working with human cells that show reproducible protein expression, meaning canonical marker characterisation is needed only once.
Optimised protocols
Access optimised ICC protocols that support diverse immunocytochemistry applications and help improve experiment efficiency and timelines.
Antibody recommendations

Fig 1. Immunocytochemistry characterisation of ioMotor Neurons. Representative ICC images show nuclear staining with DAPI (top left) and expression of canonical motor neuron markers ChAT (top right), TUBB3 (bottom left), and ISL2 (bottom right). Images demonstrate clear marker localisation and single-cell resolution suitable for phenotypic analysis and imaging-based readouts.
Defined ioMotor Neurons provide a reliable starting point for immunocytochemistry applications by enabling clear marker detection and single-cell resolution imaging. Their consistent identity and morphology support efficient ICC workflows, helping reduce variability and improve phenotypic interpretation.

Immunocytochemistry supports the detection of disease-associated protein localisation changes in human muscle models. In ioSkeletal Myocytes, ICC enables comparison of control and disease states at single-cell resolution, supporting phenotypic analysis and disease modelling workflows.

Representative immunofluorescent staining, analysed on day 14, shows MBP-positive ioOligodendrocyte-like cells (green) co-cultured with ioGlutamatergic Neurons expressing NF-200 (red) and TUBB3 (red), ioMicroglia expressing IBA1 (yellow), and human iPSC-derived astrocytes expressing S100B (yellow). DAPI counterstain appears in blue.
Immunocytochemistry reveals distinct populations of neuronal and glial cells within complex quad-cultures. For ioOligodendrocyte-like cells, ICC enables the assessment of maturation markers, such as MBP, supporting studies investigating glial contributions to neurodegenerative disease pathology.

Quantitative analysis shows an increase in the proportion of MBP-positive cells with increasing db-cAMP treatment across culture time points, supporting assessment of oligodendrocyte-like cells maturation through immunocytochemistry-based readouts.
Immunocytochemistry enables quantitative evaluation of treatment-driven protein expression changes in human glial models. In ioOligodendrocyte-like cells, ICC supports assessment of MBP expression as a marker of maturation, informing studies of differentiation and myelination-related biology.

You can use ioCells and our optimised protocols to achieve reliable data from every experiment. Simplify your immunocytochemistry applications and standardise results with consistent, defined human cells.
Immunocytochemistry applications include visualising protein localisation, confirming cell identity and purity, assessing differentiation or maturation, and detecting disease-relevant phenotypes. ICC is widely used in basic research, disease modelling, phenotypic screening, co-localisation studies, and high-content imaging to support single-cell protein analysis and phenotype assessment.
Immunofluorescence is used to detect proteins using fluorophore-labelled antibodies. It enables visualisation of protein localisation, co-expression patterns, cytoskeletal structures, and signalling dynamics. Immunocytochemistry staining is a specific form of immunofluorescence applied to fixed cells for high-resolution imaging.
Immunocytochemistry (ICC) is performed on isolated or cultured cells to investigate protein localisation and phenotype at single-cell resolution. Immunohistochemistry (IHC) is performed on tissue sections to study protein expression within native tissue structure. Both rely on antibody-based detection but serve distinct experimental and clinical purposes.
Immunohistochemistry (IHC) is routinely used in clinical pathology for tumour classification, biomarker detection, identifying infectious agents, and informing treatment decisions. Unlike ICC, which focuses on isolated cells, IHC provides protein-level information within intact tissue architecture.
A reliable ICC protocol requires well-defined marker expression, high-quality primary and secondary antibodies, and optimised immunocytochemistry staining steps for fixation, permeabilisation, and blocking. These factors support reproducible immunocytochemistry applications by ensuring accurate protein localisation and clear imaging outcomes.
