Immunostaining Service
Introduction
Immunostaining is the gold standard for visualizing protein spatial expression in the CNS, supporting the analysis of cellular health and neural connectivity. High-resolution immunofluorescence and high-content screening enable reliable validation of 3D neural models and therapeutic mechanisms.
Our Immunostaining Service employs optimized protocols and advanced epitope retrieval to minimize background interference and non-specific binding. It provides high-fidelity protein localization and stereological analysis, ensuring accurate CNS model validation and efficient drug development.

Immunostaining Service
Our Immunostaining Service is a professional, high-precision histological and cytological detection service, dedicated to visualizing and quantifying specific proteins in neural cells and tissues. By utilizing specific antigen-antibody binding reactions, combined with advanced fluorescent or chromogenic labeling technologies, we accurately localize and detect target proteins, providing intuitive and reliable morphological and molecular evidence for neurotoxicity assessment, neural research, and drug development. The service features high specificity, reproducibility, and quantitative accuracy, fully meeting the needs of basic research and preclinical detection.
Neurotoxicity Detection Methods
- Neuronal Marker Staining: Target key neuronal markers (e.g., Beta-III Tubulin, NF200, MAP2) to detect neuronal integrity, neurite outgrowth, and morphological changes, evaluating structural damage caused by neurotoxic substances.
- Glial Cell Staining: Stain astrocyte markers (GFAP), microglia markers (Iba1), and oligodendrocyte markers (O4) to observe glial cell activation, proliferation, or apoptosis, reflecting glial-mediated neurotoxic responses.
- Synaptic Marker Staining: Detect synaptic-related proteins (SYP, PSD95) to quantify synaptic density and distribution, assessing neurotoxicity-induced synaptic damage and dysfunction.
- Apoptosis & Stress Marker Staining: Combine immunostaining with apoptosis markers (Caspase-3, TUNEL) and stress-related proteins (HSP70) to distinguish neurotoxicity-induced cell death types and stress responses, clarifying toxicity mechanisms.
Service Applications
| Neurotoxicity Assessment of Compounds | Evaluate the neurotoxic potential of drugs, environmental chemicals, pesticides, and food additives by detecting changes in neural markers, supporting early safety screening in drug development and environmental risk assessment. |
| Neurological Disease Research | Study the pathological changes of neurodegenerative diseases (Alzheimer's, Parkinson's) by staining disease-related markers, exploring the role of neurotoxicity in disease progression. |
| Neural Model Validation | Verify the purity, differentiation degree, and functional integrity of neural models (iPSC-derived neurons, 3D Brain Spheres) through marker staining, ensuring the reliability of subsequent neurotoxicity detection. |
| Preclinical Regulatory Support | Provide standardized, quantitative immunostaining data and images, supporting regulatory filings for drug safety evaluation and neurotoxicity research. |
| Basic Neural Research | Assist in exploring the molecular mechanism of neurotoxicity, such as the effect of toxic substances on neuronal differentiation, synaptic formation, and glial cell function. |
Workflow

Case Study
Researchers compared c‑Fos immunostaining between long‑term stored whole brain tissue and brain slices. They performed immunofluorescence imaging and quantified c‑Fos+ cells in PL, IL, and CG subregions of the medial prefrontal cortex. Results revealed reduced c‑Fos detection in stored slices, confirming that long‑term slice storage impairs antigen recognition and immunostaining performance.
Fig.1 The damage of c-Fos in the medial prefrontal cortex was detected by using immunofluorescence staining after long-term preservation of brain sections.1

FAQs
Q: How do you ensure antibody specificity in complex CNS tissues?
A: We utilize a multi-step validation process, including the use of C-terminus-specific antibodies and secondary-only controls. We actively avoid legacy clones like 22C11 that are known to produce false positives in TBI and Alzheimer's models.
Q: Can you handle 3D organoids or only 2D sections?
A: We are specialists in 3D validation. Our platform is specifically designed for deep-tissue penetration of antibodies in brain organoids, allowing for full-volume stereological analysis.
Q: What measures are taken to reduce background autofluorescence?
A: We employ several strategies, including specialized chemical quenching agents and shifting detection to the far-red spectrum, where biological autofluorescence is lower.
Q: Is it possible to stain more than three markers at once?
A: Yes. Through our high-content screening platforms, we can develop custom 4-channel or 5-channel fluorescence panels, provided the spectral properties of the fluorophores allow for clean separation.
Q: How does your service compare to standard university core facilities?
A: While core facilities provide access to equipment, Creative Biolabs provides 20 years of expert protocol optimization. We offer guaranteed signal-to-noise ratios and advanced data interpretation that university cores typically do not support.
Creative Biolabs provides a full suite of immunostaining solutions, from rapid staining kits for morphological analysis to custom high-content immunofluorescence services. We specialize in complex samples such as spinal cord tissue and brain organoids, delivering accurate, reproducible, and artifact-free results. Our expert team supports your neurobiological analysis and speeds up research and drug discovery.
